How to remove extrude/shell without overhang

edward_sinclair

Hi, I would like to shell this part in one direction or extrude remove up to the opposing surfaces with an offset. Is there a way to do this easy or any other methods/approaches I should be using to achieve this? The problem I am having is I cant work out a way to hollow out the selected faces without breaking through the opposing side.

Thanks.

extrude remove up to the opposing surfaces with an offset

Here is how you can do it that way. You create a sketch and create an offset of the face with amount you want to shell by and then do a remove extrude up to next with an offset distance.

Split the part into two parts. Shell each part, and boolean add them back together.

@bladec I didn't realize that "Up to next" would work that way! In fact, I've never found an "up to next" that worked for me, so I always use other workflows.

You really DO learn something new every day.

@bladec You are an absolute legend. Thank you so much.

I have tried this a couple times before, but for some reason it never worked the way I expected. I thought it wasn't possible, couldn't be done. But today, I can see the light of a new dawn.
