3D scan reworked in AC ?

Hello all,

Some year ago I did a 3D scan from an object (about 80 cm)
Question is, is there a possibility to rework this in autocad ? The file is
in txt format with all x,y,z coordinates. As the scan was done in 3 parts,
they are not nice fitted. I have were low experience with autocad but a want
to change a bit the model (it's a rc model V-boot) and create afterwards the
drawings (slices) from it on paper. Maybe this is more a question for a
onther software, but as I can't work with other software, I prefere to keep
it in AC. If there is also a possibilty to export it to some popular 3D
viewing format, it would be nice. Some one wants to give it a try ? I can
mail you the file if you want to.

Thanks for any reply.

 

I think I can do this for you (changing a 3d-scan to a surface or
SOLID-model) within AutoCAD using some of my LISPs.
Send me the sample to

For import AutoLISP is ideal, and AutoCAD is also good enough to take
the millions of points and faces, compared to SolidEdge, 3dsmax, ...

But the real problem will be how to create the mesh (again easy with
autolisp) and then smooth the mesh (not so easy), to get rid of most of
the unneeded points and polygons.

Then you have to find something like a smoother plugin for 3dsmax.
For reworking such a large mesh AutoCAD is also not quite suitable. You
have to do that with a software specialized for meshes.

I tried that also with some 3dscan, and ended up writing my own (pascal)
program to import a smoothed version (80% smnaller) of the mesh into 3dsmax.
