Hello!!
I've trying to use this new tool at v9.2. I have desing and archimedian spiral, just for fun, it will turn into a log spiral soon but I have a problem. The primitive is given a thickness but when simulating it shows an error about abc3d. I attach the source code. Could somebody help me?
Thanks in advance and forgive my english :S

Have you tried defining a mesh operation->surface approximation on the object ?

First of all thanks for your replay

Yes I have, but I'm not an expert at that option. Could you please tellme how to do it?
Did you try the model? I'm not sure it was correctly uploaded I upload it again
