Posted: Fri Oct 23, 2009 6:57 pm Post subject: scaned model problem
I hope someone will help.
I scanned an object using 3d scanner Revscan, and after that I tried to edit the model in Geomagic. I don't have any expirience in this, but I'm an average SolidWorks user. My intention is to import scanned data in SolidWorks and create drawings for production.
When I tried to open .stl file, SolidWorks will only import it as graphic model (becouse of polygon limit) and I can't do anything with it. So, I played a little in Geomagic (I am a total novice) and managed to make surfaces, then exported it as STEP and imported in SolidWorks. Now I dont know what to do with it, It has many curves and looks bad.
Do I have to draw a model myself using a scaned model only as reference or what? Please help, I intend to give a drawings to production people in our company, so they can produce a copy. The model is an air compressor holder, metal casted.
Please explain your way of editing 3d scaned data and preparation process for production.

I have a been in working in the reverse engineering business for 6 years and have learned some techniques to help you through your problem. What it sounds like is going on from your explanation is you have created a (dummy parametric solid) or a (shrink wrapped water tight surface model) in Geomagic. That creates a problem in Solidworks because the model is uneditable. Which means it is a dummy parametric solid. I have had a few of these projects myself and it was a big learning curve to accomplish the final class A parametric smart solid model with the design tree. If you still need help write back. Maybe I could help you with your solid modeling projects that you are struggling with.
If you have Solidworks premium edition, you can import STL and do remodeling using the Scanto3D add-in. Go to tools-add-ins and check the Scanto3D checkbox.
Go to file-open and change the file format to MESH FILE.
* Don’t select STL as file type, make sure you select mesh file so you will be able to edit it.
After that the mesh file can be edited and used for remodeling using the Scanto3D toolbar.
I think that is your best shot if you are an experienced Solidworks user.
In VxScan, the REVscan software, you could also use the decimate triangles function in the facets node. This would help Solidworks in managing the file.
