Projecting Geometry to Curved Surfaces

By David Melvin, PE, TEDCF Publishing

This tip uses Autodesk Inventor 2012 to demonstrate how to create a sweep along a curved surface like this one. The technique described in the tip can be used to create features that are far more complicated than cosmetic designs.

Projecting Geometry to Curved Surfaces

The Trick
The trick is to project the path onto the surface using the Project Geometry to Surface command.

The Process
First you need to have a curved surface. There’s no need to use this procedure on a flat surface.

The next step is to draw the shape of the path on a 2D Sketch. You may have to create work planes to get the right sketch orientation. It also helps to add a work point so that you can project it to the surface, and then use it to position the profile.

Exit the sketch, and then create a 3D Sketch. Once you’ve done that…
