Help flatting this model
(OP)
I have exhausted all the flatting option I know. I used Catia v5 r20 and went through all the things I usually do to flatten non-intelligent solids and surfaces models.
I also used Solidworks 2010 "convert to sheet metal" command which got me close, but solidworks hates the tips of this part and excludes them form the flatting.
I calculated the bends with my calculator like the old days and came up with 6.3 inch overall. I milled the flat pattern and the brake guy formed it, then CMM bought the part off.
But I’m wondering why it never flatten using the cad tools we have. Can someone try to flatten this part please? I really want to know what you some up with.
Thank you

But why not do this directly in sheet-metal workbench ? You could do this directly with an extrusion for instance.

I always for get about the hopper. Thank you for the step by step.
Yes the thickness not being constant is a issue on lots of parts we receive. I usually use the Generative shape design-> extract function and generate a constraint thickness using the Part design-> Think surface command.

Great I came up with 6.421. Thank you for your help, I learned a lot.
What steps did you take to correct the tangency errors?

Edit and constrain the geometry in the sketch. I would start with dimensional constraints then move to tangency constraints.
If you are using GSD
Try joining the surface data and play with the angular tolerance. You can also turn on the check tangency option to show the problematic areas. If the angular threshold in Join does not tweak it enough you can use the Healing command on the problem surfaces.
If you have access the HA (Healing Assistant) module, you could heal the internal patches of a larger join.
