====== Sketchup ======
Trimble Sketchup is a 3D modelling software. A very efficient tool to 
create building models or avatar symbols which can be exported from sketchup directly into ive-file format which can be used in TERRA 4D.

===== Installation =====
  - Download the Sketchup version 2017, 64bit and install it.
  - Download the SketchupToOpenSceneGraph extension from our ftp server or ask your contact person to send the extension.
  - Open SketchUp and select Menu "Window/Extension Manager"
  - In the Extension Manager Window press "Install Extension" on the bottom
  - Select the extension file "sketchupToOpenSceneGraph-v1.6.5-su2017-win.rbz" and click open
  - The extension "Export to OpenSceneGraph (via COLLADA)" should appear in the list; make sure the extension is enabled.

==== Usage ====
Now you can export to IVE file format via menu "File/Export to OpenSceneGraph".
Select either "Export entire document to IVE..." or "Export selection to IVE...". Use the default settings in the export dialog.

==== Known issues ==== 
On some systems run-time libraries are missing. In this case you get an error message when exporting to OpenSceneGraph.
To solve it please contact us to get the suitable Visual C++ redistributables ("vcredist_x86.exe") and install it. 

When using an older extension (sketchupToOpenSceneGrah) the models might appear very dark in Terra 4D Viewer. Please use the latest extension version.
