how to convert point cloud to solid object in AUTOCAD?

Hi,
Anyone can help me?
I have a data file about my face. It is a txt file which only
includes X Y Z position data. I can import it into AUTOCAD and see the
face. However, It is only a point cloud. I want to convert it into
surface and then a solid model.
This is interesting because once I get the solid model, I can export
a stl file for Rapid prototyping and make something interesting.
Does anyone know how to convert point cloud to solid object in
AUTOCAD?
Thank you very much.

Dear flint2001:
Google Advanced Autocad script "point cloud" 15,100 appropriate hits
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:

the fourth of a four part training session (may be too basic for your needs)

command list, looks like the faces might be converted by 3DFACE, and the 3D faces made into a solid by SOLID?
Good luck.
