Error "AttributeError: 'NoneType' object has no attribute 'type'"

Hi,

I'm trying to create a quality mesh based on a model boundary and some breaklines. It always prints the follwing error message: 'AttributeError: 'NoneType' object has no attribute 'type''
I tried to use dividing constraints or leave them away. Both versions resulted in the same error message. What am I doing wrong? I printed the complete error message at the end of the post.

Cheers
Dominik

Re: Error "AttributeError: 'NoneType' object has no attribute 'type'"

Apparently there is a problem with one of your input geometries. Try the meshing without breaklines first, if this work, your breakline layer causes the problem. Did you draw the lines yourselfe or import them from another source?

Indeed, I had problems with the input geometries. I had to clip my breaklines to the system boundary and afterwards it worked fine. I got the input data from a third person, didn't really check them before. Well, now I know for the next time... ;-)
Thanks heaps, Stephan!
