    Method for splitting quads with not coplanar vertices? —Willy Tschager
   hi folks, I had a little chat with carsten about the possibility to fix not coplanar vertices automatically in LDDP. we all know that running a line like this: 0 4 16 10 -1 10 10 0 -10 -10 0 -10 -10 0 10 through L3P with –dist 0.1 or –det 0.001 will (...)

   (...) I wouldn't bother too much. I think it is an error if the four points of a quad do not lie in a plane. Too bad that the LDraw format has a built-in possiblity of creating degenerate quads. POV e.g. uses 2D points to describe a polygon. (...) I (...) (22 years ago, 27-Jan-03, to lugnet.cad)

     (...) Because I'm lazy? Unfortunately SourceForge has too many features for me to remember how to use them all. I went through their official release building process once at version 0.9.1 and promptly forgot how to do it. Now I wish I'd never done (...) (22 years ago, 27-Jan-03, to lugnet.cad)

   (...) I think you have to look at the part and determine which vertice is wrong and correct this vertice with corrected coordinates. Niels (22 years ago, 29-Jan-03, to lugnet.cad)

        Re: Method for splitting quads with not coplanar vertices? —Orion Pobursky
     (...) You are right, ther are way to automatically fix the problem. But one noncoplaner quad can cause many such errors on quads that are perfectly fine. Therefore the bast way to fix this will most likely always be to manually find and corrent the (...) (22 years ago, 29-Jan-03, to lugnet.cad)

     (...) There's not really a way to automatically fix the problem, if it was caused by an error in a vertex's position. That almost has to be fixed manually. Steve (22 years ago, 1-Feb-03, to lugnet.cad)
