Please help me with the solution for the offset curve




I used a ‘clipper’ to make an offset curve inside the panel.
The plane setting was resolved using the ‘Deconstruct Rectangle’.
However, when I zoomed in and looked closely, I found an excitation on the panel plane.
To solve this problem, I used ‘offset on surface’ to solve it, but this time I’m not able to delete the intersection line inside.

Question1) How do I fix the plane setting when I use the ‘clipper’?
Question2)How can I trim an internal intersection if I use ‘offset on surface’?

Clipper only wants planar curves.
Offset on Surface is good, but you forgot to join the curves after Brep Wireframe.

It’s simply worked out.
Thank you.
