SketchUp Release Notes

What's New?
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:

On Win:
PrivatePreferences.json is saved to C:\Users\[user name]\AppData\Local\SketchUp\SketchUp 2018\SketchUp SharedPreferences.json is saved to C:\Users\[user name]\AppData\Roaming\SketchUp\SketchUp 2018\SketchUp

On Mac:
Both PrivatePreferences.json and SharedPreferences.json are saved to /Users/[user name]/Library/Application Support/SketchUp 2018/SketchUp

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.

LayOut and Style Builder Release Notes

What"s New? Better LayOut, Much Better Drawings

LayOut is where people harvest their 3D work in SketchUp to produce excellent drawings. Without apology, our commitment in LayOut is to help professionals make much better drawings, much quicker, and with as much control as they need.

Preferences

• Your existing user preferences will now migrate when upgrading.

Scaled Vector Drawing

Now you can use LayOut"s vector illustration tools to draw in 2D at scale. Use your SketchUp model as a scale basis to create blocking details. Or create your own scaled illustration to add details not necessary in your 3D model: dashed lines or blocking, for instance. Re-set scales as you wish and your work will resize as necessary. As you would expect, your scaled drawings are fully supported by LayOut"s Dimension and Label tools.

DWG Imports One reason that drawing in 2D at scale is important is that a lot of LayOut users are trying to work with imported AutoCAD geometry via the DWG format. So in this release, we"re introducing LayOut"s ability to import DWG files as native LayOut entities. DWG projects import at scale and support the pages, titleblocks, and blocks that your partners have created. Even better, LayOut users can now help themselves to the vast world of free DWG libraries.

• Paper Space
  • Paper Space is the default setting on the importer that will bring in AutoCAD Paper Space data 1:1 and Model viewport data (if available) at the predefined scale. If the incoming AutoCAD drawing has multiple Paper Space options, the user has the ability to select a different one via the dropdown menu.
• Model Space (Only)
  • Checking the Model Space (Only) option will bring in only the Model Space data at full size 1:1, place it in a scaled group that is then fit to the current paper size. This is an arbitrary scale and can be changed to whatever scale you choose.
• SketchUp model reference
  • Checking the SketchUp model reference option will bring in the viewport and the Model Space (Only) data as a scaled SketchUp model reference.

All imported data is brought in at the scale and units based on the AutoCAD file. AutoCAD files that contain a perspective view either in the Model Space or within a Viewport are brought in as a SketchUp model reference by default.

Group Edit

To support scaled drawings, we made a juicy change we think LayOut regulars will notice right away: Editing grouped entities in LayOut now works just like it does in SketchUp including single entity groups. That means it"s wayyyy easier to draw and manipulate grouped entities. LayOut users can also control "rest of document" visibility when editing within a group. Does anyone else smell a new custom keyboard shortcut?

Drawing Tool Improvements

In this release, we have made a number of improvements to how you are able to draw. To keep track of them all we have listed them out.

Multi Viewport Dimensioning

What sounds like an enabling physics concept for teleportation is actually a pretty simple LayOut idea. You should be able to draw dimensions across SketchUp viewports in order to create an excellent section detail like this…

Precise Dimensions

You can set the same level of dimension precision in the LayOut Dimension Style panel as you can in SketchUp. You can now be as precise as SketchUp dimensions. That"s up to 0.000001 inches. Do the math: that means LayOut can show the decimal equivalent of 1/64" (0.015625").

Advanced Attribute Labels

Like all of the information in your model, SketchUp"s new advanced attributes are available when you draw LayOut labels.

Other LayOut Improvements Entity Locking

Similar to group editing, locking entities is fundamental to how many people organize and navigate projects (both models and documents). Now you can easily lock individual LayOut entities to cut down on accidental edits or selections. We can"t guarantee you"ll be less awkward at parties.

• A number of translation truncation improvements.

SketchUp and LayOut API Release Notes

What's New? LayOut Ruby API for SketchUp

This is a new Ruby based API for SketchUp that allows developers to read and write LayOut files using the regular SketchUp Ruby API. We've taken the existing LayOut C API and wrapped it with a Ruby layer and then included that inside SketchUp. This is proving to be a great working model for how to expose API functionality to our base C API and then expose that exact functionality to a ruby layer without duplicating code.

Sketchup.send_to_layout

Along with the LayOut Ruby API for SketchUp we added the ability to open LayOut files with the LayOut application. This gives developers the ability to write a SketchUp extension purely in ruby that parses the SketchUp model, writes a LayOut file and opens the LayOut file in LayOut in one smooth motion. This helps create a stronger connection between SketchUp and LayOut and can improve user workflows through the use of developer created extensions.

ImageRep

Hello Ruby API developers, meet Sketchup::ImageRep. This new class exposes a data structure internal to SketchUp called an ImageRep. ImageRep is an in-memory representation of an image (as opposed to a reference to an image inside the SketchUp model). This class exposes a number of image reading and manipulation tools to the Ruby API. Now you can get the color of a pixel at a specified uv coordinate from an ImageRep, get an array of all pixel data from an ImageRep, set pixel data in an ImageRep, save an ImageRep out to disk, and more. Of course we've also included utilities to convert an in-model texture to an ImageRep, and assign an ImageRep object directly to a material as the material's texture. This new class opens up a lot of opportunities to read and manipulate images in the model. Check out the ImageRep class in Ruby API docs for more information.

Exposed Importer/Exporter Options to Ruby API

We have exposed all the options for our native importers and exporters to Ruby. See the Ruby API documentation on Sketchup::Model.import and Sketchup::Model.export.

New SketchUp Features in the API

A big round of applause for the SketchUp Core team for the improvements they have added to the SketchUp application. Well, we also wanted to make sure that these new features were accessible to our developer community. We have introduced new API features for Named Section Planes and Filled Section Cuts. Awesome!

Ruby Documentation

You've probably already seen this feature in action at ruby.sketchup.com. We have been working to improve our Ruby API documents and the publication process. At the beginning of the year, we switched from an internally tweaked and maintained version of RDoc to YARD for our documentation generation. In the process we had to make many alterations to our documentation in the source code. We made a specialized YARD template to suit our needs. The Ruby documentation will be available to Beta testers within the Resources section of CenterCode. If you are especially interested in helping with our Ruby Docs, you can even fork our repository, make changes, and submit them to us via a pull request and we can incorporate those changes back into our source code and they will go live the next time we update the online docs.

Ruby Handling of Advanced Attributes

SketchUp core added a feature called Advanced Attributes. This adds some new attribute dictionaries and attributes to Component Instances and Definitions by default on every model. It should be noted that we have blocked the ability to delete the dictionaries via ruby. This should not be possible, please let us know if you find a scenario where you are able to do so. You can however delete the key/value pairs. The UI will recreate those key value pairs if they do not exist.

• Added options for all 3D exporters and imports

Bug Fixes

• Breaking Change - Fixed a bug in Sketchup::Material.name= which allowed the API to create materials with duplicate names. Now it will raise ArgumentError if it's not unique to the model.
• Breaking Change - Changed Sketchup::Color class to be common between LayOut and SketchUp. The potentially breaking change is that Sketchup::Color changed to now compare RGBA values instead of the ruby objects.
• Breaking Change - Changed Geom::Transformation.identity? So that it now properly returns true in all cases where the transformation matrix match the values for the identity transformation.
• Fixed Geom::Transformation.scale(float) and Geom::Transformation.new(float) to not set the 15th component of the matrix, but instead adjust the other fields.
• Fixed a crash when trying to call Sketchup::View.animation from Animation.stop
• Fixed a crash when calling UI.menu with empty string.
• Sketchup::Page.erase_page will now correctly delete the Scene tab, like the UI does.
• Fixed a bug in Sketchup::ArcCurve.end_angle where it sometimes added 360 degrees to the returned value.
• Fixed an issue where a Ruby Importer could cause the Import file dialog to render the drop-down items incorrectly under Windows due to pipe characters in the description.
• Fixed a crash when using -RubyStartup command line argument with a file that raises errors while loading.
• Fixed a crash in UI.create_cursor that would happen if the length was less than 4 characters.
• Fixed a rare crash in MaterialsObserver.
• Removed the Break Edges option in Windows for DWG importer

Documentation Note: When an HtmlDialog is closed, all callbacks to that instance are cleared. Re-attach them if you need to open the dialog again.

SketchUp C API Additions and Improvements

We added new classes and functions to the SketchUp C API in 2017 to provide greater benefit to our developers and as part of our continued effort to fully deprecate and remove the old C++ API. We are continuing to add more until we gain enough coverage to consider the C API at feature parity with the deprecated C++ API. Reference the versions.txt file within the SDK to see the new additions. The preferences dll in the SDK is now required to use the C API. A change from previous versions.

Additions with a * indicate that there were multiple functions added in that class.

• Added SUScene*
• Added SUSectionPlane*
• Added SUText*
• Added SUTextureGetAverageColor
• Added SUTransformation*
• Added SUVector2D*
• Added SUVector3D*

Fixed SUMaterialSetName: now returns SU_ERROR_INVALID_ARGUMENT if the material is owned by a model and the name is not unique

LayOut C API Additions and Improvements

• Added SU_ERROR_ENTITY_LOCKED error codes to applicable LO*Set* methods to support LayOut's new Entity Locking feature
• Changed LO*SetName methods to return SU_ERROR_UNSUPPORTED if the name string is an empty string
• Added documentation for an undocumented return possibility (SU_ERROR_SERIALIZATION) in LOImageRepSaveAs
• Added documentation for an undocumented return possibility (SU_ERROR_NO_DATA) in LODocumentCreateFromTemplate
• Added documentation for an undocumented return possibility (SU_ERROR_NO_DATA) in LOStyleGetDimensionUnits
• Added documentation for an undocumented return possibility (SU_ERROR_OUT_OF_RANGE) in LOStyleSetStartArrowType
• Added documentation for an undocumented return possibility (SU_ERROR_OUT_OF_RANGE) in LOStyleSetEndArrowType
• Added documentation for an undocumented return possibility (SU_ERROR_OUT_OF_RANGE) in LOStyleIsArrowTypeFilled
• Added documentation for an undocumented return possibility (SU_ERROR_OUT_OF_RANGE) in LOStyleSetSubEntityStyle
• Added documentation for an undocumented return possibility (SU_ERROR_OUT_OF_RANGE) in LOStyleGetSubEntityStyle
• Added documentation for an undocumented return possibility (SU_ERROR_UNSUPPORTED) in LODocumentRemoveAutoTextDefinition
• Added LOAutoTextDefinitionListRef, which is an object that can be used to iterate over all of the LOAutoTextDefinitionRef objects belonging to a LODocumentRef

• Added LOAutoTextDefinitionGetMandatory
• Added LOAutoTextDefinitionGetIndex
• Added LOAutoTextGetDocument
• Added LODictionaryClear
• Added LODictionaryGetNumberOfKeys

• Added LOGroupSetScaleUnits
• Added LOGroupRemoveScaleFactor
• Added LOImageRepGetDPI
• Added LOLayerGetDocument
• Added LOLayerInstanceGetIndexOfEntity
• Added LOPageGetDocument
• Added LOPathAppendPathTo
• Added LOTableGetBorderStyle
• Added LOTableSetBorderStyle
• Added LOTypedValueGetString
• Added LOTypedValueSetString

Modified LOLinearDimensionCreate to set the initial leader line type to LOLinearDimensionLeaderLineType_Bezier instead of LOLinearDimensionLeaderLineType_Hidden.

Breaking change to LOFormattedTextGetStyleRunAtCharacter. This was previously mis-implemented. It now takes in a starting character index and a length, and returns a LOStyleRef object with style attributes for the specified run of characters.

Breaking change to LOSketchupModelGetExplodedEntities - an exploded raster-rendered model will now wrap the LOImageRef in a LOGroupRef.

Modified behavior of LORectangle and LOEllipse after ApplyTransform - previously these entities would incorporate the given transform by adjusting their intrinsic position to match the transform. As a result, invoking GetTransform after a SetTransform would return a recalculated transform matrix. With the new behavior, these entities will preserve the transformation matrix sent to SetTransform.

Known Issues:

Sketchup::Material.name= has a regression bug where setting the name to the existing name will also raise an error. (unintended). And that renaming the material via the UI might prevent the API from reusing the name until the model is reopened.

Recommended new pattern for setting material name:

material.name = materials.unique_name('Hello World')
