Removing material between two objects

Anonymous — Fri, 15 Oct 2021 19:24:10 GMT

Hello,

I apologize if this question has already been answered and if it has please point me in the right direction. Is it possible to join two objects in an assembly and constrain them to where they need to live and then remove the material where they connect? I am trying to place two cylindrical components together and then have the space where they meet be open. Any help would be greatly appreciated.

Yes, but you can only remove material in an assembly and it won't push through to the part file if you open that separately (unless you use an add-in from the app store)

Constrain everything, draw a sketch, then use extrude to cut.

Again, the cut will only exist at assembly level.

To do it at part level:

Double click the part to edit in place.

create a sketch and use the project geometry tool to copy the geometry you want from the other part.

Draw your shape.

Use extrude to cut.

Repeat with the second part.

A screenshot or attach your attempt so far would also help to give the best solution.

Here's what I would use:

1) Simplify both objects into one single-solid part, but keep seams between faces:

2) Project the intersection and extrude cut:

Result:

The problem is if your intersection is not as simple/linear as that... then use sculpt:

This worked perfectly. Thank you!

Another way to approach this is to define the two parts as separate solid bodies in one part file, then derive them to separate parts. The attached files are 2022 format (I don't see where you mentioned what version you're using).
