Divide he path in several segments and sweep them individually.

Give the helpers some time. They are helping you in their spare time and don't get paid for it.

Thanks Chris.
I know you guys volunteer to assist so I apologize for sounding impatient.
You're helping a lot of people to see the true power of this software and the workarounds that newbies need to know.

Randomly mixing Part WB and PD WB often leads to problems.

Nice! So what role does the comb play? First time I hear about the parametric comb.

Is it possible to make this into a solid with thickness of, say, 2mm? Like a pipe
