how to cut or trim a parametric curve ?

Hi,

I'm trying to make a 3D coil using parametric curve and sweep, but I need to cut a part of my curve, I can't change it by equation, so i just need to cut a part of it. In solidworks we used to do this by trim. Any Idea how can i do the same in COMSOL.

Indeed is there any changes or difference in results, when we do 2D modelling on MEF module for coil design with 3D modelling?


Thanks in Advance
