I love SketchUp… just not sure it’s appropriate for what I’m trying to do. I think it’s not really designed for solid CAD and really is mesh. I don’t really understand the difference all I know is…
My workflow is:
- generate object in specialist program, export with “Nurbs to STL” (rather than nurbs to dxf or step… or exporting profile/outline etc separately to reassemble)
- reduce the poly count with meshlab down from 18,000 to 250
- import STL into SketchUp
By the time it’s in SketchUp there’s a bunch of holes in the model. SolidInspector helped me figure that it’s not happening at the Meshlab stage.
I then try to plug holes manually but being a very curved object (surfboard) it’s a massive task even with FixSolid and SolidSolver. I then try to improve the process using ExtrudeTools but I can’t get my head round it.
My next move I think is to bring the STL into some other kind of program and then resave…then bring back into SketchUp.
However… I notice a lot of people use Rhino and SolidWorks. Surfboard shapers don’t have enough cash for these so I assume it’s pirated software. I wonder if I should be using a Solid CAD program like that (find something free like Autodesk123D?) rather than working around Mesh problems?
If so, where to start with that?
