How to project a curve perpendicular (normal) to one or several meshes.

The result of the projection is a degree 1 NURBS curve on the mesh. Construction history is supported so that if the input curve is modified, the degree 1 curve generated on the mesh updates.

1. Do one of the following:
   • Select one or more meshes, then choose Mesh > Mesh Curves > Mesh Project Normal from the tool palette.
   • Choose Mesh > Mesh Curves > Mesh Project Normal from the tool palette, then select one or more meshes, and press the Go button.
2. Select one or more curves to project, then press the Go button.

   The curves are projected onto the mesh(es) and degree 1 NURBS curves appear on the mesh.

3. Modify the input curves if necessary.

   The projected curves on the mesh(es) update.

   Note

   These projected curves are often referred to as curves-on-mesh.
