1. What is BlendUp?

BlendUp is a Blender exporter plugin for SketchUp available for Windows and Mac.

2. Which softwares do I need to use BlendUp ?

You need the following softwares to run BlendUp:

  1. SketchUp 2014, 2015 or 2016, Make or Pro version for Windows or Mac
  2. Blender Version 2.74 or above for Windows or Mac. Blender should be associated to .blend file opening (default behavior)

Please note that we can’t support Linux at the moment as the SketchUp SDK is not available on this platform.

3. How to install BlendUp?

  1. Close SketchUp if necessary
  2. Download BlendUp for your SketchUp version
  3. Open the downloaded zip file
  4. Execute the file contained in this zip
  5. Launch SketchUp

You should see a new entry called “BlendUp” in your file menu.

You need now to configure your Blender path. For that, click the menu entry "File/BlendUp/Options", click OK and select the blender.exe path on Windows (Blender.app on Mac). After the confirmation dialog, you can start exporting.

4. How to convert my SketchUp model to Blender?

In SketchUp, open “File” menu, select “BlendUp”.
Click on “Export” and select the destination of your Blender file. That’s all!

5. The plugin doesn’t work for me!

Feel free to contact us with the following details:

  1. SketchUp and Blender versions
  2. Operating system version
  3. Does it fail for all SketchUp model or a specific one? If it is a specific model, please join the model to your mail.

6. How to create my own material library?

By default BlendUp exports a plain diffuse material. You can of course edit this material in Blender but if you export again, you will still get the same diffuse material.

How to keep your changes? Don't use "Export" but "Append" and select the blender file containing your modified material. Your SketchUp model will be added to the blender file and reuse existing materials if their names match with SketchUp ones.

7. How to export big SketchUp models to Blender?

SketchUp models can have many many instances of the same components however Blender has a lot of difficulties to display more than 1000 nodes in the hierarchy tree.

Our solution: use the "Use Blender Groups" option. Each SketchUp component definition will be turned into a a Blender group stored into a specific scene. This way you can load very big models as the main scene doesn't display groups internal hierarchy.
Please note that in this mode, to edit a specific group, you need to select the corresponding scene.

8. What is the use of the "Append" function?

"Append" adds a SketchUp model to an existing blender file and try to reuse existing materials and groups (the match criteria is based on the name of the material and the name of the group).
That's a very easy way to create your own material library. See point 6.

9. I don’t understand export options!

Ok, here is a description for you:

  1. Unit: choose between the metric system or the imperial system.
  2. Rendering: choose between cycles rendering (recommended) or Blender internal rendering.
  3. Use Sun Shadows: when enabled, it creates a blender directional light matching SketchUp sun.
  4. Export as Quads and N-Gons: disable this option to export triangles only.
  5. Export Scenes as Cameras: disable this option to prevent the creation of cameras matching SketchUp scenes.
  6. Simplify Materials: each SketchUp face has a front and back material. They can be the same or they can be different, it is up to the designer. If you activate this option, only the front material will be kept. You will get simpler materials to edit but you may get some errors for faces where front and back materials are different.
  7. Mark Edges: if you are planning to use EdgeSplit modifier / to unwrap / to use Freestyle, then all visible SketchUp edges will be marked for you.
  8. Keep Hierarchy: disable this option to export your entire model as one mesh.
  9. Use Blender Groups: activate this option to turn SketchUp component definition into Blender groups. Each group is store in a specific scene. This option should be activated for very big models (see point 7)
  10. Keep Cut Openings: use this option to keep the hole made by a component cutting the opening of a face (window or doors for instance). When activated, the component is exploded inside Blender.

10. My rendering is very noisy!

Increase the number of samples. A range between 1000-2000 should give you good results.
