I have been searching for good tool to export a sketchup model to any 3D CAD format. Our company uses Sketchup Pro Ver 17 and would like a way to export to parametric modeling tool such as Autodesk Inventor. The only company listed in the Extension Warehouse reporting to provide this feature is Okino Graphics so I contacted them and was informed that exporting from a mesh moddler (i.e. Sketchup) to CAD DOES NOT WORK. Yes you can export as a 3D dwg format which looks OK however it is next to impossible to modify in AutoCAD. One would think that exporting from one Autodesk product to another should not be a problem however, this is definitively not the case.
Our engineers like to use Sketchup Pro to develop the basic model and then hand off to the CAD designers to completely reproduce in AutoCAD or Inventor. Not very efficient use of resources and hope that Trimble will put some money into developing a usable export utility. If there is anyone in the community that successfully was able to export the model in a usable CAD format I would be interested in knowing what utility was used.
