I know my subject is somewhat mis-named, because I gather that you cannot really extrude from a 3D sketch, however I am looking for a way to accomplish what extruding a cut from a 3D sketch would accomplish.
The problem is this: I have a simple 2D sketch that I've projected onto a curved surface (imagine a square projected onto the outside of a hollow cylinder). Now that I have a 3D sketch on the surface of the cylinder, I want to use that sketch as a "cookie cutter" through one wall of the cylinder.
If I were to simply extrude the cut from the 2D sketch, the "cookie" is wider at the edges than at the center. I want the cut to be perpendicular to the projected 3D sketch at all points.
I've attached a simple example that illustrates my problem.
Can anyone help? Thank you in advance!

Split and Thicken-Cut
Emboss might also be a solution.
I know this is old, but good god, you just saved me so much time. We do a lot of odd shape and transition HVAC style ducting, this saves my life!
Thank you, thank you, thank you!
Hi! This is an old post. On Inventor 2016 and later, you can use Ruled Surface command and select a 3D Sketch to extrude in a given direction. Then you can use the surface to split or sculpt a body.
Many thanks!
