how to convert point cloud to solid object in AUTOCAD?

Dear flint2001:

Google Advanced Autocad script "point cloud"

You could attempt to connect each point with two other unconnected points, and make a sheet of triangles (as 3D surfaces)...

Reverse engineering something, are we?

Thank you very much. I tried point cloud plug-in for AUTOCAD. Later on, I use another kind of software to convert the data file into dwg file. Also, I can make these points a mesh surface in autocad. The problem is I don't know how to make it a solid model only which can be transfer to stl file. You are right. This is a small project of reverse engineering. Thank you again

How many points are contained within your point cloud? Unless the number of points is fairly small (less than 1,000), I doubt that AutoCAD is the appropriate tool for your project. Do you have access to any other CAD tools - preferably solid modeling or surfacing tools?

I think you'll need to give the surface some small thickness to make it a solid, like extruding the surface 1e-6 or something. There might be a way to offset the surface by a thickness.

Those are general suggestions. I'm not familiar enough the newer AutoCAD versions with solid modeling to give specifics.

Dear flint2001:

Go to Autodesk:

Good luck.
