3D Meshing and Solids

[n.murray]

Is it possible to convert 3D objects created with surface meshing to 3D solids?

[mjfarrell]

From the following Knowledge base article it seems that it
is a 'one-way' street. And from your description of what you want to do
you are going the wrong way! At least where autocad is concerned.



Three dimensional objects, including regions, solids, meshes, objects drawn by extruding or revolving, Boolean operations, and solid models can all be converted into polyface meshes or 3D faces.

Solution


To convert these type of objects:


Use the 3DSOUT command to export objects from a drawing. Use the default settings.

Open a new drawing.

Enter 3DSIN on the command line.

Select the new drawing you just created.

From the 3D Studio Import Options dialog box, choose the Add All button.

Choose OK.
The objects will load into the drawing as polyface meshes.

To create 3D faces from the polyface meshes, explode the polyface meshes.

Hi

Check out the lisp file m2s.lsp (can be found at any of the following locations) -

xarch AutoCAD (http://xarch.tu-graz.ac.at/autocad/news/lisp_progs/ghindex.html)

M2S stands for Mesh to Solid I presume? I can tell you that the lisp doesn't work for AutoCAD 2005...

Command: appload
m2s.lsp successfully loaded.

Command: ; error: malformed list on input

Hi

M2S.lsp has a Copyright notice within it's header therefore I suggest you contact the person (there are a couple of contact E-mail addresses within the header) and see if they have an updated version or are willing to update the routine for AutoCAD 2005.

Have a good one, Mike

there used to be a command called solidify, but I cant remember if it worked with meshes
(old r12 stuff)
