Originally posted by moyo Hmm..., as a noob i have not heared about the 4- side fact. But cannnot you do a triangle and then do a planar surface?

Problem is: a trim doesnt actually cuts nothing... the plane is still a plane, just that the "outer" range of the surface is not visible... hit F8 an youll see the CVs(and youll be able to edit em)... but thats bad because you cant stitch trim edges nor modify the surface selecting and trying to move em or in any other way...
