Re: Problem with my very first design

["tano1938" <rgarritano@xxxxxxxxxxx>]

I changed the tolerance and it got rid of the most of the problems 
but I noticed that if the dxf file has a line with three points 
defining it, i.e. two lines in series, the mesh program hangs up and 
the program must be shut down in the windows task manager. Editing 
the file by replacing the two lines in series to one line cures the 
problem.

Thanks for the help.
