#Disappearing Faces
7 messages in this thread
Help!
I am trying to create an animation of a site for our Waste Management
department. I am DXF'ing in a series of TIN's (triangulated irregular
network) models that were created using our in house software. When I DXF
it into both Microstation and AutoCad (11 or 12) there is nothing wrong.
But once it comes into 3DS R1, I can only see the faces from the bottom.
Once I pass over the top, I can see right thru the wire mesh! i am REALLY
confused. I have loaded from our software successfully before. Has anyone
seen this before? If so, how do I fix it? I need to put this to a video
by then end of next week, so I am in a teeny tiny bit of a rush.
Thanx for listening….. later.

PS (Please address this to me, since several of us from this company log in
and they might get my mail first.)
Peter, if you're using 3DSr1, you ought to be using the external DXF3DS.EXE
utility to convert DXF files into 3DS files with automatic coincident
vertex welding and surface normal unification. Better yet, you ought to
upgrade to 3DSr2, since you're doing yourself a massive disservice by using
r1 with r2 available. Your problem is due to surface normals, and a good
rule of thumb is to use 2-sided materials when rendering cad models.
However, that is MUCH MUCH MUCH slower in 3DSr1, and hardly a performance
hit at all in 3DSr2.

PS: DXF3DS.ZIP is in the 3D Studio DL library here in the forum.
Thanx for the fast answer. I will see if I can get R2 asap! I know that I
need it, its just whether or not I can get the guy who signs the bills here
to agree!! <grin>
I will you the 3dsdxf again and see how it goes.
Later.
Peter.
Peter Nice to see I'm not the only environmental consultant that works
weekends (or that's interested in 3DS). If you're looking for a copy of
3DS R2, I may still have one for sale (of course it would be cheaper to
upgrade your Version 1). Cheers Doug Ritcey Pollutech Geotechnical

Thanx, I am going to call my vendor my Monday morning to see how much the
upgrade'll be. Maybe I'll get back to you after she does…
Thanx.
Pete.
I'm sure you'll do much better with an upgrade than by buying mine
(upgrades are a lot less expensive than a new version!). However, if you're
trying to reach me, I'm going to be drilling in Sarnia all week – you can
try my mobile (and voice mail) at 416-520-9645 and I'll call you back.
Good luck!

Thanx Doug… I've got the OK on the upgrade now, its just the 2 to 2 1/2
week wait that I've got to handle now… 😉
Later.
Pete.
