SketchUp - 更新履歴

• Advanced Attributes
  Advanced Attributes allow you to embed useful information into your model when creating and managing components.
  You can now define the Price, Size and URL attributes when creating or editing components,
  as well as defining Owner and Status attributes for each component instance via the Entity Info dialog.
• Aggregation in Generate Report
  We want to make the information in SketchUp models as useful as possible.
  In this release, we’re improving Generate Report to allow users to aggregate component data so you can extract and organize information contained in your models.
  That means you can configure Generate Report to sum parts and quantities for schedules and cutlists,
  or create detailed pricing estimates by listing prices by layer.
• IFC Export Improvements
  BIM doesn’t really work if information can’t move freely between applications.
  We’ve dialed in our IFC exporter to ensure that the attributes you bring in from other applications or manipulate in SketchUp stay with your work when it leaves SketchUp.
• Named Section Planes
  It seems simple, but naming something is the first step towards making it easier to find,
  organize, and edit that something.
  Now, even when your section planes are hidden, they’re right at your fingertips.
  Here’s how it works…
  Create a new section plane and choose a name for it and a short symbol that will display in your modeling window.
  Your section plane is now a unique SketchUp entity that can be found in Outliner and manipulated in Entity Info.
  Use Outliner to quickly find, select and edit specific planes.
  Use Entity Info to edit naming conventions and organize section cuts into layers,
  then control the visibility of your section planes,
  cuts and fills via Styles.
• Filled, Styled Section Cuts
  We have added Filled Section Cuts to SketchUp 2018.
  To access, open Styles Edit Modeling and toggle ‘Section Fills’ on or off, and set your desired fill color.
  When section fills are toggled on, SketchUp will render a fill on top of cleanly modeled sections.
  We’ll even help you troubleshoot geometry problems that are preventing SketchUp from recognizing the section you want to fill.
  Access troubleshoot mode through the section plane context menu when Section Fills are on.
• Section Plane Performance
  While we were at it, we improved performance for models that use section planes to hide large amounts of geometry.
  Basically, the more geometry you section off, the more you’ll benefit!
• Other Notable Improvements and Changes Outliner
  While adding support for Section Planes,
  we also improved Outliner’s performance. Outliner no longer refreshes on many transactions that don’t need it.
  Additionally, we improved the sort order in Outliner.
  Changes include:
  Sorting based on Component Instance and then Definition instead of sorting based on one long string.
  This also applies to Section Planes - it will sort first based on the Section Name and then the Symbol.
  Sorting numbers in a more intuitive way.
  Sorting is now case insensitive,
  which means a mixture of capitalized and lowercase words sorts in a more intuitive way.
• Drawing Improvements
  We made some small, smart changes that help you draw exactly what you want. Including:
  Draw a rectangle about its center using modifier keys (Ctrl on Win and Option on Mac).
  Employ quicker control for rotated rectangles.
  We switched the order of entry in the VCB so you can quickly enter a dimension with no angle.
  Improved workflow with Tape Measure Tool.
  Edge length and face area are now instantly displayed in VCB as soon as user gets “On Edge” on “On Face” inferences.
  Added color coding to Freehand tool.
  While drawing, it is colored the same as the axis it is perpendicular to.
  Reduced display of arc/circle inferences after second click of any drawing tool.
• STL Import/Export
  The SketchUp STL extension is by far the most popular download from Extension Warehouse.
  Going forward it might not be, because now SketchUp natively supports the import and export of STL files (on both desktop and web).
• Anti-aliasing on the Mac
  For Mac users, we’ve added anti-aliasing settings.
  Go to SketchUp Preferences OpenGL to control the anti-aliasing sample count,
  which controls the smoothness of your geometry.
• Preferences Location
  The majority of preferences are now stored in two json files.
  There are still some OS controlled preferences that remain in the registry (Win) or plist (Mac).
  The json files are saved in the following locations:
• DWG Importer
  The DWG Importer has been rewritten using our own C API.
  The goal is that the new dwg importer will work exactly the same as the 2017 version (improvements can come at a later time,
  now that we have code we can update and maintain more easily!).
  Ideally all files that imported previously will continue to import in 2018 and hopefully some files that used to fail on import will now import correctly.
• Support for macOS High Sierra
  Our QA team has smashed and banged on Apple’s newest operating system,
  macOS High Sierra, enough to say that SketchUp 2018 is fully compatible.
• Bug Fixes/Small Improvements
  In addition to the above, we’ve been heads down fixing bugs and adding some smaller features:

• Fixed a frequent crash that could occur when inserting components and doing other actions
  (e.g., renaming a component, deleting entities, changing component properties).
• Fixed a frequent crash that could occur when copy/pasting geometry that needs to be merged with hidden geometry.
• Fixed a frequent crash that could occur when doing a copy/rotate after having cancelled out of a previous copy/rotate by activating another tool.
• Fixed a frequent crash that could occur on some systems with AMD/ATI graphics cards.
• Fixed a crash that could occur when opening/working in some models with unfixed validity errors.
• Added a fix for a non-reproducible crash that could occur when using the Rectangle tool.
• (Mac) Fixed an issue where simultaneous Component Browser searches led to SketchUp crashing.

• Made updates to Measurements toolbar entries for tools:
  • A closing bracket is now added automatically when an opening bracket is entered for both square and angle brackets related to point and delta input such as [nn,nn,nn] and (in US locale).
  • (Win) SketchUp now recognizes both the decimal and list separators that are set within the Windows OS.
• Fixed an issue with the Rotated Rectangle tool where entries in the VCB (Measurements toolbar) were not working as expected after the second click.
• Fixed an issue in which Dimensions or Text would snap to a sub-component origin instead of the component origin.
• Fixed an issue with the Tape Measure tool in which a model would not rescale when measuring two points on a face and entering in a value in the VCB (Measurements toolbar).
• Fixed an issue with the Tape Measure tool in which you could not infer from a face to create a guideline along another face.
• (Win) Fixed an issue with the Tape Measure tool where guides would toggle off when using Ctrl + Z to undo a previous operation.

• Fixed an issue where materials on faces could be lost or faces could be flipped after modifying geometry in certain cases.
• Fixed an issue where an offset of an ellipse would sometimes offset as a circle.
• Fixed an issue where color swapping/pixelation would occur on very small textures.
• Improved Checkup’s messaging for graphics cards that report inaccurate memory information.
• Improved our ability to get diagnostic data on startup crashes.
• Fixed an issue where the letterbox bars were displayed incorrectly when the Advanced Camera Tools’ aspect ratio did not match the current window.
• Fixed an issue where Advanced Camera Tools did not correctly export 2D images.
• (Mac) Fixed an issue where users on certain iMacs were not able to export to 2D graphic containing transparent backgrounds.
• (Mac) Fixed an issue where exporting a 2D graphic with a transparent background would produce jagged edges on certain iMacs.
  These artifacts could also be seen in LayOut.

• (Win) Fixed a crash that could occur on startup on some machines.
• (Win) Fixed an issue in which UI::Notifications didn’t appear within localized builds of SketchUp.
• (Win) Added Chromium Developer Tools.
• (Mac) Fixed an issue in which SketchUp could not be launched due to an OpenGL error on some machines.
• (Mac) Fixed an issue in which layers were not sorting correctly when sorting by visibility in the Layers dialog.

With SketchUp 2017, we have completely reworked our graphics pipeline - i.e., the way we display SketchUp models.
This was a massive change that will allow us to innovate far beyond what we have been able to do in the past.

This new graphics pipeline has stricter hardware and software requirements than in previous versions of SketchUp.
To run SketchUp, you will need:

• A 64-bit operating system.
• A graphics card that supports OpenGL 3.0 or above.
• A graphics card that supports Hardware Acceleration.
  We will no longer support software rendering!
• A graphics card that passes a series of tests that are run by SketchUp 2017 to assure that your card is capable of rendering SketchUp models.
  These tests include checks like compilation of SketchUp's GLSL shaders and support for OpenGL framebuffer objects.

If your machine does not meet these requirements, you will see an error dialog when launching SketchUp,
LayOut, Style Builder, and Viewer that lets you know which requirement you did not meet and which will prevent you from running SketchUp until you fix the error.
If you see this error dialog, try upgrading your graphics card driver - upgrading your driver is a good first troubleshooting step and often solves the error.

The SketchUp 2017 modeling window is now “DPI aware”.
In SketchUp 2016, we scaled the User Interface (toolbars, cursors, etc).
In SketchUp 2017, we are now scaling content in the modeling window so that you can better see the masterpieces you are creating!
This work includes larger, scaled inference graphics and linework and updates to our inference icons.

The Extension Manager is the new way to manage how extensions interact with SketchUp.
Users will be able to install, uninstall, enable, disable and update extensions from this new dialog.
In addition, users can set their extension loading policy through this same dialog.
This is a complete replacement for the extension and extension loading policy areas previously found within the System Preferences dialog.
The Extension Manager can be found within the Window menu on both Windows and Mac.

As always, we are looking at ways to improve our core modeling tools and inferencing.
This release is no different. Here's a brief description of what's new:

Improved Offset tool: Previously the Offset tool would create overlapping or self-intersecting geometry.
We've changed the tool to automatically trim these overlaps to create clean boundaries with no overlaps.
The old functionality is still available via a modifier key.

Rectangle tool plane and shape locking:
The Rectangle tool now works with arrow keys to lock the plane normal to an axis or surface.
This includes the ability to lock off-axis planes using the down arrow key.
Now the Rectangle tool matches the inferencing capabilities of the circle and polygon tools.
Additionally, pressing shift can now lock the proportions of a square or golden section.

Rotated Rectangle tool plane locking improvement:
The Rotated Rectangle tool now respects a locked plane across all steps for the tool.
If you chose a surface to lock the tool to at the beginning, this orientation will persist throughout creating your rectangle.

Perpendicular to Face inference:
We added the ability to hover over any surface and then find an inference for the direction perpendicular to the face.
The drawing line and reference surface will be highlighted in magenta and a new “Perpendicular to Face” tooltip will be displayed.
Note it is not possible to force this inference using the down arrow key but it can be locked once it appears by holding shift.

Component Origin inference:
We added a new “Origin in Component” inference point which now provides the ability to find and snap to a component's origin.
This inference shows up whether there is geometry on the origin or not and has higher priority over other inferences.
It shows up automatically when you hover over a selected component or group with a drawing tool.

Persistent IDs for entities have been added to SketchUp 2017.
This feature is useful to developers and allows us to improve interoperability between LayOut and other products.
A unique, persistent ID number is now internally assigned to geometry when it is added to a model.
This includes unique IDs for edges, vertices, faces,
and more that will be maintained even if the geometry is moved, rotated, or scaled.

It is now possible to customize SketchUp's red, green, blue, magenta, and cyan inference colors.
If you have trouble distinguishing red from green or would simply like to customize your SketchUp colors,
it is now possible under SketchUp Preferences > Accessibility.
If you change these settings, you may notice that the axis colors will get brighter to match your selected direction colors exactly.
In SketchUp 2016 and earlier versions, the axis colors were slightly muted relative to the inference colors.
Also note that if you adjust your colors, SketchUp will continue to refer to red, green, and blue axis directions in tool tips, the status bar and the Instructor.
Inference Icons (end-points, mid-points, on edge, etc... ) are also unaffected by this feature and will remain their original colors but we have updated the shapes to improve visibility.

Additionally, a new “Color Blind Style” has been added to the “Color Sets” styles library.
Use this style as a base for dialing in your custom colors and shades.
It is intended to help maximize people's ability to see when inferences appear.
Since there are many different types of colorblindness, you may need to edit this style to best fit with the colors that work for you.
Once you are done, don't forget to set up a template with your new style.

When you launch SketchUp, we are now much smarter about choosing the ideal graphics card settings (i.e., the ideal “Pixel Format”) to make SketchUp run the best it can.
Previously, we sometimes selected settings that didn't allow models to display as well as they could have and which had a negative impact on performance.

As part of this work, we have made it easier for you to change your multisample anti-aliasing settings in Preferences > OpenGL on Windows.
Note though that we have chosen the setting that we think is ideal for your graphics card and that if you choose too high of a setting, performance and possibly stability may be affected.

We have added a “Warning“ section to Preferences > OpenGL > Graphics Card Details to show any potentially negative conditions related to your graphics card so that you can take actions to improve your situation.
Note that if your graphics card shows warnings, you will see a big warning icon on the Preferences > OpenGL dialog with some text that explains you need to click the Graphics Card Details button for more information.

We have standardized where product content,
stuff like collections of components, materials and styles are stored on the file system.

On Windows, we moved the default content that comes with SketchUp (Components,
Materials and Styles) out of the Program Files directory and placed them in the ProgramData directory.
And on both Windows and Mac, we created Components, Materials, Styles and Templates folders for your user related content.
By default, these folders are in the following locations:

Note that if you store your content in these folders, it will show up in the Components,
Materials and Styles browsers without you having to do anything and your templates will show up on the Templates pane as well. Additionally,
users no longer require special privileges in order to modify the contents of these folders.

We have made it easier for you to access your content by adding new functionality to the Preferences > Files pane on Windows and we added this Preferences pane on the Mac.
Simply click the Open in Explorer/Finder buttons to access your content vs. having to remember the folder locations listed above.

We now present the create component dialog when converting a group to a component.
This allows users to set the full range of component attributes when converting instead of having to go back and edit the resulting component in Entity Info or the Components dialog.
This workflow helps a great deal when using the Solid Tools on components.
The Solid Tools still create groups but it's quick to use the create component option to redefine your desired component definitions.

Our QA team has smashed and banged on Apple's newest operating system,
macOS Sierra, enough to say that SketchUp 2017 is fully compatible.

The Trimble Connect Extension has been rewritten to utilize changes to the Trimble Connect and SketchUp Ruby APIs.
Updates and new features include:

• Sign in: You can now use a Trimble ID or a Google account to sign in.
• Improved File Management: We've reworked the Open and Publish dialogs to make it faster to browse through your projects on Connect.
• Collaboration Manager: A new dialog which allows you to create and manage ToDos,
  manage reference models and add comments about a model.
  The buttons across the top allow you to see the various panes: ToDos, Comments, Reference Models and Launch Trimble Connect
• ToDos - Create and Manage ToDos from the Collaboration Manager.
  Note that in order to view ToDos they must be associated with the model you are working on in SketchUp.
  If you want to view all the ToDos in a project use the full Connect web interface by Connect Icon in the upper right of the collaboration manager or accessing Connect in a web browser.
• Comments - Click the icon showing two speech bubbles to view the comments pane. There you can view the comments for a model and add new comments.
• Improved Model Referencing - Click the chain link icon to view the Reference Model pane.
  At the bottom of the Reference pane there are buttons for importing a new reference model as well as deleting or updating all existing reference models.
  Click the arrow next to a specific reference model to edit its alignment and save that adjustment back to a project.
  You can also individually update a reference model by clicking the Cloud + arrow icon next to the reference model's name.

In addition to the above, we've been heads down fixing bugs and adding some smaller features:

• Fixed several crashes that could occur when opening or working in models that had a texture with no associated texture image.
• Fixed a crash that could occur when printing a model with sketchy edges.
• Fixed a crash that could occur when printing large models with textures.
• Fixed a crash that could occur when exporting an animation that has watermarks and scenes with different edge styles.

• (Mac) Fixed a crash that occurred when closing a file with either the Dimensions tool or Texture Position tool active.
• (Mac) Fixed an issue where SketchUp would sometimes crash after adding a location to a new model.
• (Mac - Sierra) Fixed an intermittent crash that could occur when quitting and discarding changes with multiple documents open.
• (Mac) Fixed a crash that could occur when closing a document after switching between documents.

• Re-wrote how we display transparency, including making the following changes:
  • Improved performance significantly.
  • Improved the accuracy of the appearance of the model.
  • Removed “Medium” transparency from the Transparency Quality dropdown.
    Pre SU 2017 models which use “Medium” transparency will now default to “Faster” transparency.
  • Added an “X-ray opacity” slider which applies when x-ray mode and nicer transparency are selected (defaulting to 65% for nicer transparency and remaining at 50% for faster transparency).
  • Improved the enable/disable behavior on the Face tab of the Styles dialog so that the controls are enabled only when they will actually change the model.
• Fixed an issue where shadows on face me component flashed in exported animations.
• Fixed an issue where, when using color by axis, lines could incorrectly display as if they were on axis when they were not.
• Fixed an issue where the selection highlight for a nested section plane looked wrong.
• Fixed an issue where alpha images did not display when using the wireframe face style (when other images did display).
• Fixed an issue where the leader for view-based text drawn close to faces drew incorrectly.
• Fixed an issue where sketchy edges could appear blurry when using the Maximum Texture size option.
• Fixed an issue where the face selection highlight did not display correctly when using the Fade Similar Components option.
• Fixed an issue where nested section planes did not always cut geometry as expected.
• Fixed an issue where components in large models degraded to bounding boxes / other display elements dropped out of the model faster on AMD cards than other graphics cards.
• Fixed an issue where materials incorrectly displayed as transparent when material transparency was off and x-ray was on.
• Fixed an issue where the ground plane could z-fight with faces when in top view.
• Fixed an issue where, when turning off section cuts, the foreground image of a matched photo was not always displayed.

• Elements in the modeling window (e.g., edges/edges effects, inference icons/linework, selection highlight,
  the matched photo/texture position grids, the model/component axes,
  guides, text/dimensions and the component bounding box) are now scaled and should look better on high DPI monitors
• Select region for edges and general “snapping” is now scaled and should improve selection on high DPI monitors.
  This will change the way SketchUp “feels” on larger resolution screens or when the display has been scaled in the OS preferences.
• Updated inference icons graphics including new “Origin” inference icon.
• Updated Position Texture tool icons.
• (Win) Fixed issue where tool cursors would not show up when using shortcuts until the mouse was moved with Instructor dialog open.

• Added Instructor content for Rotated Rectangle to reference click and drag functionality.
• Fixed an issue with the Circle/Polygon tools in which they could snap to axis inferences that didn't exist when off axis.
• Fixed an issue with the Circle/Polygon tools in which they seemed to disappear during drawing and couldn't be completed when the radius was aligned with the axis normal to the circle/polygon.
• Added error checking when entering number of segments in the VCB (Measurements toolbar) for Arcs/Circles/Polygons.
• Removed the visual cues (endpoints and center) for Arcs/Circles/Polygons at small pixel views. Zoom in to see the cues if they are not visible.
• Fixed an issue where an arrow key axis constraint was not released as expected if the last visited edge was outside the locked plan for protractor based tools.
• Fixed an issue with protractor based tools where the locked/unlocked plane tooltip would continue to show and highlighting would not reset after pressing escape.
• Fixed an issue where a parallel inference was lost after escaping out of Arc, Pie, and Move tools.
• Fixed an issue where the Line, Tape Measure, and Move tools would lock a direction using arrow keys before first click.
• Fixed an issue with the Move tool in which the angle value in the VCB (Measurements toolbar) did not always update appropriately when rotating with the Move tool while on an inference.
• Added ability to inference original selection set when using rotate/copy.
• Fixed an issue where an inference remained locked when panning followed by orbiting after having released shift.

• (Mac) Fixed an issue with Rotated Rectangle in which it could snap to an angle that was one degree off of what was expected.

• Updated labels for Components/Groups in Entity Info (“Name” changed to “Instance”) and Create Component Dialog (“Name” changed to “Definition”) for added clarity.
• Group Instance name is populated as the Component Definition in the create component dialog when converting a group to a component.
• Revised message when editing or reloading a component with locked instances to clarify what will occur.
• Fixed an issue in which the file name could be truncated when trying to reload a component that was previously imported or downloaded from 3D Warehouse.
• Added ability to modify one instance of a component with Solid Tools and have all instances reflect that change by leveraging the updated group to component workflow.
  After modifying with a Solid Tool, right click and select Make Component,
  choose the definition name to be overwritten and this will then replace all instances of the component.

• Fixed an issue where Add Location buttons could overlap each other.
• Fixed an issue where the Add Location dialog could display poorly at high DPI.
• Fixed the Add Location window from resizing when grabbing consecutive locations.

• Fixed the error message that was displayed for expired private network licenses.
• Fixed an issue in which a license was unable to be activated if there was an e character in the username.

• (Mac) Fixed an issue where SketchUp did not show user created material folder if they were named the same as our standard material folders.
• (Mac) Fixed an issue in which a material could be replaced unexpectedly when in edit mode and selecting a different In Model material.
• (Mac) Fixed an issue where the icon for the Trim tool was incorrect.
• (Mac) Fixed an issue where SketchUp could get confused when moving your cursor between two open models while drawing.
• (Mac) Fixed an issue where fonts printed larger when Vector Printing was selected.
• (Mac) Fixed an issue where a material's HSB values were not refreshed to show the values for the material being edited.
• (Mac) Fixed an issue where the Preferences dialog could disappear behind the SketchUp drawing window when clicking in the drawing window.
• (Mac - Sierra) Fixed an issue in which a crash message appeared when toggling section planes or section cuts from the View menu.
• (Mac - Sierra) Fixed an issue in which you could see duplicate icons in the dock when launching SU and File > Send to Layout was grayed out.

• Fixed a crash when saving a model after importing a .dwg file that had a component definition name the same as one already in the model.
• Fixed a crash that could occur when auto-folding certain geometry and using an arrow key to lock direction.
• (Mac) Fixed a crash that could occur when opening a new file or switching documents while in the middle of some operations (including importing a 2d image, viewing an image igloo, or using the Dimensions/Text tool).
• (Mac) Fixed a crash that occurred by deleting an in model component’s definition name or description via the Components browser dialog.

• Fixed an issue where SketchUp was incorrectly parsing negative lengths for specific formats such as feet and inches (e.g. -2’ 8”) and fractional (e.g. -15 1/2”) when entered in the VCB (Measurements toolbar) or the Ruby Console.
• Removed Shift + Press Alt (Win) and Shift + Press Command (Mac) functionality from Rotate and Protractor tools which freed the center of the protractor.
  Shift + Alt functionality clashes with the Windows shortcut default setting that changes keyboard language on Windows if multiple languages are installed. The down arrow key provides the same functionality.
• Fixed an issue with the Protractor and Rotate tools in which the protractor jumped to the corner of the screen when making multiple slope entries in the VCB (Measurements toolbar).
• Updated the Section Plane tool so it is colored based on the axis it is normal to when being placed (for consistency with other tools).
  Also, added a tooltip to indicate “Unlocked plane” or “Locked plane”.
• Added ability to Circle/Polygon tools to use Shift to lock through different point inferences (including endpoints, midpoints, arc centers, and guide points).
• Fixed an issue with Arc, Pie, Circle, and Polygon tools in which the tool could remain locked to a plane after releasing Shift with the down arrow key active.
• Fixed some cosmetic issues with several tools in which the drawing line could be incorrectly colored when locked with the down arrow key.
• Fixed a cosmetic issue with surface based tools in which the tool cursor could be incorrectly colored when locking with an arrow key and parallel to an axis plane.
• Fixed a cosmetic issue with several surface based tools in which the tool highlighted in magenta when pressing Shift to lock normal to an axis.
• (Win) Fixed an issue in which Entity Info accepted arc/pie/circle/polygon segments that were out of range as specified by an error message.
• (Mac) Fixed an issue in which you couldn’t update two consecutive arcs/pies/circles/polygons with the same number of segments in Entity Info.
• (Mac) Fixed an issue where arc/pie/circle/polygon segments temporarily updated to 0 or last valid entry in Entity Info when an invalid entry was made.

• Fixed an issue where the drawing window took focus away from extension dialogs.
  This impacted our shipped extensions (e.g. Component Options, Photo Textures) and some external extensions (including Brighter3D and SU Podium).
  In some cases extension dialogs appeared to disappear but were located behind the SketchUp window.
• Made a change so that the visibility of an auto-hide tray does not toggle by way of the Window menu or a shortcut as toggling this way caused the tray to immediately retract.
  The visibility of an auto-hide tray is only managed with the tray tab (hover over tab to display tray).
• Fixed an issue in which renaming an entity in Entity Info didn’t save correctly when subsequently clicking in Outliner.
