Hi. Can anyone tell me what am I doing incorrect? I can not make a shell for life of me.
Using shell makes naked edges.
Deleting top faces and making face offset does same.
Making solid offset does the same.
Tried all settings.

this may help-
or, it’s a pretty easy fix to just repair, rebuild the surfaces that misbehaved.

fwiw, working with simpler surfaces on the outer surfaces will make the inner surfaces work better-
if you have not watched this series, I highly recommend it. A healthy dose of single span would help this model a lot.
Thanks for replay.
Wow, the result you are getting is awesome. I am clearly doing something wrong.
When rebuilding, do I select only surfaces that are adjacent to the naked edges are everything in the model? With just the surfaces next to issue I completely break the model. With all surfaces I get no change.
Could you share the exact commands and params you used for repair / rebuild? I’ve been trying to do that for quite a while with no success.
Also, thanks for the links to videos. Started them now. I was thinking I have to learn to use match surfaces instead of lofting everything to make those corner surfaces simpler. Guess the video series will have something on that.

OK, I am trying to do the cleanup.
- I fixed the primary curves to be 2nd degree max
- I still have some issues with surfaces (the ones blended in corners.
- I used the rebuild to fix ones on bottom - made them 2nd and 3rd degree U and V
- Joined naked edges with tool under analyze->edges
- Tried doing the same for the top ones. When I run rebuild, it does not effect the selected surface but whole top side - all 3 faces there.
Tried even to extract the surface and move it away from rest of the model - still same.
Can anyone tell me what am I doing wrong? From looking at the YT vids and reading forum entries, I do it right but the result I get is confusing me.

Can I use this model to do a YT video on how to repair this part?
It’s a good case to show common problems…

You’re not going to get very smooth transitions to the sharp surface, or at most the transition is smooth but over a very small distance. I would construct something like the attached, and then eventually split, refine, match to the edges:

note: I matched the side surface point location to the front surface to make the transition a bit more natural
Sure. It’s for project I am doing for my own company.
Hi again. What YT channel do you plan to put the video on?
it will be on Rhinoceros3d on youtube, where all our other videos go.
sorry for the delay, with pascal retiring the tech load has shifted a bit and some of my video plans have gone to the back burner.
video here-
