Wings3D export - invalid mesh faces

[Monster]

Hey I tried to open a map file extracted from Wings3d as a bzw file.
I didn't work and showed me this after the try:

Excuse this maybe udmb question, but what went wrong?
I'm learnig wings3d and everything about map making right now.

Try Body->CleanUp on the mesh before exporting,
It seems that you have co-located vertices.

[optic delusion]

Two other wings options that can help with invalid faces are....
Select-->By-->Isolated vertices and
Select-->By--> non-planar faces (this can help a lot with drawinfo conversions)
There is a small problem with selecting non-planar faces. Wings resolves to three decimal places and bzflag resolves to four. You have to reset the selection preference to .0001 every time you do it, or wings will report all faces are planar, but bzflag will not agree.

Ok since I'm on another pc right now, I can't try it immediately, but I'll try it soon and post again.
Thank you for your quick replys.
thx Monster

Hm,
I tried all three options, but none could help me.
When I used the "CleanUp" option it would collapse my object, unless i didn't disable "isolate verticals"
The other two options (Select-->By-->Isolated vertices and || Select-->By--> non-planar faces) worked find, but couldn't help me with the problem.
I still get about 20 invalid-mesh-face-errors.
Is there another way to get my object into a map?

[trepan]

I took another look, and it turns out that the invalid points aren't co-located,
they're co-linear, example:

vertices 7 8 9 # 50 34.0677 49.9263 75 34.0677 49.9263 100 34.0677 49.9263
-> (y is always 34.0677)

This setup is invalid for bz's purposes. Remove the faces, no more errors ...

[anomaly]

I have had these errors before when trying out new maps. They never keep the map from loading though. As trepan said you can usually delete the faces safely. One other thing, make sure your models are saved as triangles. This seems to help.
