To Project a Curve on a Facet Model, a Datum Plane, or a Surface
1. Click Restyle > Projection
2. Select a curve for projecting. You can also select the curve before clicking Projection.
3. Select the faceted geometry, the datum plane, or the surface on which to project the curve.
When you project a curve on the facet, the projected curve is created as a curve on facet.
When you project a curve on the datum plane, the projected curve is created as a planar curve.
When you project a curve on the surface, the projected curve is created as a curve on surface.
