Fusion Shell Surface Irregularity

[huczekdesign]

Hey everyone,

New here to the forums but been using Fusion for about a year now. I'm working on an enclosure and I've ran into an annoying shell problem. When I shelled my body 2mm, what was a straight direct cut into the body, created a wavy irregular surface on the inside of my body. Obviously I'd like to fix it but more importantly I'd like to know what I did wrong to confuse Fusion so that I don't run into this again.

Here's a pic so you can see what I mean.

Thanks!

Anthony

Without having access to the design file that is hard to say. Can you share your design? (export as .f3d an attach to next post)

I don't see anything irregular - all looks normal to me in picture.

Oh sorry about that I should have highlighted the surface to call that out. Here you go. This should be flat along the z plane.

Ok, now I see it.

I think the only way to diagnose the cause is with access to the file.

File>Export and then Attach the *.f3d file here that exhibits this behavior.

Edit: Can you roll back the Timeline to exactly the feature before this issue and then the feature when the issue appeared.  Attach the two images here.

Do I see multiple Shells in the same body?

Sorry I can't share the file but I did take your advice and pull the timeline back to where the issue was created and making some slight adjustments to my numbers, that fixed the issue! It must have just been struggling to calculate something, I'm not sure. 1mm won't affect my design so I'll take it ha 🙂

Thanks again.
