# How to project a curve on a plane?

I have a bezier curve and a plane as below. I would like to project the curve on the plane. Is this possible?

• Do you mean cut the curve into the plane, of just flatten the curve to the plane? May 13, 2022 at 9:24
• @RobinBetts, I think I want to flatten the curve to the plane...not sure though :) I would like the curve to be projected to the plane in the mathematical sense. Right now it is a curve defined in the XZ-plane, it should be projected from the XZ-plane onto the plane defined by the mesh plane in the picture. May 13, 2022 at 9:26
• Hmm! Good question! This is trickier than it seems at first. If you convert to a mesh, and are happy with that shape, then OK to; eg; 1. create custom orientation from the target face, 2. set pivot point in that plane, somewhere, and 3. Scale to 0 in Z of your custom orientation. Or: 1 Set snap to 'Project individual elements' 2. Align ortho view to plane with Shift-Numpad-7, and 3. tap 'G'. BUT. If you do those with the raw Bezier, it projects the control points too, and the resulting curve is very slightly different. May 13, 2022 at 10:03
