Adding Draft To A Cast Channel (Hole)

Anonymous — Tue, 22 Mar 2016 20:54:39 GMT

Hello Again,

I am designing a "block" with an internal channel (see attachment), which would be cast in plastic. In order to pull the tool out correctly, I would need to add some draft to this tube. I can do a nice sweep at a set diameter along the internal path, but it does not have draft.

Is there a good way to do this?

Thanks,

Dave

It's possible but requires some construction geometry.

First I put Plane on Path for each direction of travel inside the cube.
Then I put Axis at intersection of 2 Planes to capture the axis.
Then I put Plane at Angle using this Axis. The angle is halfway between the two planes at the intersection.
This allowed me to extrude with draft to the "mid plane", and then Loft to a new circle sketched onto the bottom.

Sorry no time for a Screencast of this today.

Cool. This works. Had to play around to find the correct axis and planes, but it works well. Thank you very much.
