I have seen the question of how to bring a SketchUp model into Revit asked on several sites. The inevitable response from some Revit user is "Why?"
Given the strengths of SketchUp as a conceptual design tool it seems only natural to want to leverage these strengths by porting what has been accomplished in SketchUp to the best available tool for design development and construction documentation, which is Revit.
The respondants to the question point out that they are able to accomplish in Revit anything that can be done in SketchUp. When one searches Google images for SketchUp and conceptual design, the results are myriad. Changing the search terms to Revit and conceptual design yields results mainly from Autodesk promotional pieces and their duplication on various sites.
If there is a question that ought to be asked, it is why this should be so.
