I often use the 3D scan app to scan sculptures in parks. These models always have some deficits. And you want to design works based on the scanned models. Can we export the models from 3D scanner and then import them to SketchUP directly?
I use Einscan-H. Make a export from your scan to OBJ with texture. Then import in SU with universal importer.
You can simplify direct, it works amazing good.
