Hi group,

I’m trying to do a sweep with a profile family along a given curve. I’ve seen that there are some posts about it already and I’ve tried to follow what are saying but they are not working.

The problem is said to be with the detection of the curves of the family. I’ve just created a profile family with a circle in it. Is there any further restriction I have to add in the profile family for getting its curves detected?

I attach images of the nodes and the family. Thanks!

Hey,

It seems that the node uses a method which was superceded, this post has an updated python script…

Here’s the dyn which Kukul created, it includes the python script…

Hope that helps,
