How to project a mesh boundary on a specific plane?

Hi Sir:

I would like to project mesh boundary on the system plane.
my process is

  1. Dulboarder to get boundary.
  2. select boundary to project “on a plane”.
    “on the plane” means the base should be a plane.

My question is how to build a vertical mesh wall?

Hi Frank - try this: DupBorder then ProjectToCPlane > DeleteInput=No then Loft' the two curves with the seam point adjustment set to 'Natural' and 'Do not simplify' in the dialog.Meshthe result.Join` the mesh to the orginal mesh.
