Blender 2.8 SketchUp Import

README: although SketchUp Make is still available at time of writing (alt download), it is no longer supported or actively developed by Trimble. Users are instead directed to SketchUp Free (account required for download), an online browser-based ‘app’ with restricted import/export capabilities (3D Warehouse support only – Pro purchase required for DAE/KMZ import/export). Note also that SketchUp and 3D warehouse models are not open source 3D models, they are typically provided under limited license conditions so licensing will need to be checked before use, including within open source projects. Easy availability does not equate to ‘free’.

SketchUp Free is a browser based version of SketchUp with heavily limited export/import capabilities.

For extensive information and instruction on exporting and importing SketchUp meshes into Blender generally refer to Import SketchUp models into Blender, the process is the same with minor differences.

Summary

TL:DR summary of the export/import process explained below;
(1) Export SketchUp scene/selection to Collada DAE or KMZ.
(1a) if KMZ, extract DAE file and misc. contents.
(2) Import DAE file into Blender using Collada import.
(3) Tidy up mesh.

SketchUp export

Before exporting from SketchUp or SketchUp Make ensure all meshes are set up as required, separated or grouped as needed and/or textured. Once done, when exporting, if the Collada DAE format is not available KMZ can be used as an alternative (see instructions on unpacking these here). Set or select any options e.g. whether the mesh should be triangulated or not (useful for game-ready models), and then export. This produces a *.dae file (or *.kmz) and asset folder containing textures.

Design note: do be aware there are commercial license restrictions associated with SketchUp Make content, models, meshes and textures are not open source – nothing can be used for commercial purposes.

Export SketchUp meshes to Collada DAE or KMZ (additional options available for Shop and Pro)
Once a model is prepped in SketchUp, export to DAE or KMZ (additional export options available with Shop and Pro).

Blender 2.8 Import

To import the Collada DAE file select that option from Blender 2.8’s File menu – File » Import » Collada (Default) (.dae). Select the *.dae file, set any import or mesh options in the Import COLLADA section lower-left and click the Import COLLADA button top-right. If successful the imported SketchUp model will appear in Blender 2.8’s 3D View positioned as it was in SketchUp.

Important: although Materials and texture references are imported into Blender, the current Material and texture display system used by Blender 2.8 means additional work may be necessary so UV mapped and assigned images appear in the 3D View.
