#3D Studio from AutoSurf
5 messages in this thread
Help! I'm trying to take information from AutoSurf/AutoCAD 12 to 3D
Studio via AutoVision. However the poly mesh unhide does not produce
very good geometry to render. Anyone come across this? Any
suggestions? Seems it should do a better job than what is does – are
there some optimum settings I should be tring to use? I need an easy
solution if possible since this is for rapid prototyping of parts.
I'd be glad to send renderings of what we got if that will help.
Thanks!
Aaron,
I deal with autosurf models everyday and have found the same problem
with the meshing algorithm. The only work around I can give you is to
decrease your mesh density or display tolerance. By default the
display tolerance is set to .005, setting it to a smaller number
creates a denser mesh, which often looks better (when rendered). The
drawback though, is that you are increasing your face count, which
increases your rendering time.
I am trying to work on a lisp routine which will create nice even
meshes out of autosurf surfaces. I haven't actually started on it.
But I have a few good ideas and some code already written that I use
for other routines. I just need to sit down and put the stuff
together.
BTW, you should have posted your message in the acad forum. The asoft
forum is devoted entirely to 3d studio and animator pro. The Acad
forum is AutoCAD, Autosurf, Designer, AME, Autovision and other
related AutoCAD add ons.
While your at it figure out a way to automatically get the diagonal
edge between two faces to come in with the edge invisible. Seems
like the old AME models would come in without every edge being
visible. <g>

That is also part of my plan, basically what my routine will do is build a new
mesh with either the 3dmesh command or most likely the pface command (if I have
the patience to figure out the vertex ordering and stuff). Don't hold your
breath on this though. I haven't really worked on it for a while. I've built
some parts of it which work independently, but it is still pretty complicated
to figure out and put togetther in one neat routine, as there are steps in
between which I have to do manually and haven't figured out how to automate.
There are a lot of different possibilities with Autosurf surfaces, and I need
to figure them out.

My hat's off to you for trying, and to all the other programmers who built
these tools. I draw the line when it comes to programming. I make images not
programs. In fact as I read through the R4 manual I started to think that Yost
when off to Planet X and forgot that we lowly earthlings didn't come along. <G>
I wish you good luck with the lisp routine, AutoSurf is a great tool with lots
of possibilities, I just have never understood why Autodesk has never found a
way to more seamlessly interface the product lines.
