Could you provide a 10~30 lines self contained command-line program that is AS SHORT AS POSSIBLE and that tries to duplicate your issue? Something in the style of the vcglib/apps/sample/trimesh_XXXX examples (just a .cpp and a .pro). From just the two lines that you are repeatedly posting is impossible to understand what is your problem. If you post just these two lines nobody can help you. The context is necessary. You should know that... The program should be AS SHORT AS POSSIBLE that is should be impossible to remove any statement (any statement) without breaking its ability of duplicating the issue. If someone post a long bug-duplication program that could be made shorter anyone will think that the submitter is either lazy or that the submitter considers his time more precious that the others one. cheers p. skunkwerk wrote: > i'm still struggling with how to add and delete faces...
