Projects one or more curves (2D or 3D) onto a surface or set of surfaces. You can project the curve along a vector or along surface normals. You can also use this command to project a point onto a surface.
You can use the command bar to specify that you want to project a single element, a chain of elements, a point, or an entire sketch.
You can select wireframe elements from multiple Parasolid bodies and the elements will remain associative.
Note:
When projecting a curve onto a cylinder, make sure that the curve's endpoints do not lie on a silhouette edge of the cylinder when viewed from the projection plane normal. Extend the edges of the curve past the cylinder edge.
