Since I’ve updated to 2017 I’ve been having a problem with Layout:
when I edit a model in sketchup, save and go to update the viewport of that model (which is referring to a saved scene in Sketchup that HAS NOT been changed) the viewport view moves dramatically.
Yes. Use scenes in SketchUp and associate the viewports in LayOut to those scenes. Do not do anytihg to the viewports that make them show as modified in the SketchUp Model inspector window. That is, do not double click on the viewport to zoom, pan, or orbit the camera and make the view selections in SketchUp, not the SketchUp Model window in LayOut.
Noe of this is different in SU2017 than in and other version.
