Cannot combine two bodies getting undefined error

evanmoore041 — Sat, 07 May 2022 17:31:02 GMT

I am trying to combine two bodies, body 82 and slider, but whenever I try to combine them I get an undefined error, and then when I try to do anything the bodies combine after the action, but it also combines a seperate body, R Mount.

Here is the f3d file:

Are you aware of Fusion 360's R.U.L.E #1 & 2 ?

I am now, I have used fusion 360 for a little over a month, so I am still learning. This was my first design that was not just one part, and I know it really should be completely redone, and there is a lot I can do now with all I learned in the process of making it, but I just dont have the time.

2 ways to fix it,

Edit the Extrude feature and change to join.

or Pull the internal face to make an overlap, Combine is finicky with flush faces.

Might help....

when I tried to set it to join, it just deletes the slider, and when I try to pull it, it works, but even when it is inside the slider, the parts wont join, instead it gives me Error: Combine23 Compute Failed

there is something strange with the slider body. At first I thought it was a case of not having enough overlap between the bodies, but even if I use Offset Faces on Body 82, it won't combine. But, I did notice that if I modify the slider body by adding a small box to it, I can combine them. We need to investigate more.

Both worked for me, here, but I had the timeline rolled back to those areas being created, and no yellow icons in play,

If that helps.
