Hello,
I have a problem resolving a sheet metal flat pattern situation.
Capture-2 shows the complete corner with on 2 sides a flange with radius from 20mm, and also the corner with a radius from 20mm.
The problem is within the corner with R=20
I modeled it as a solid box and made fillets on the 2 sides and the corner, then i used Shell and got the correct end product. Convert it into a sheet metal part, but its not possible to make a flat pattern from this.
To produce this you need 3 cuts in that corner, so you can make a flat pattern. (Capture-4: see my sketch how it must look like if it would be a flat pattern)
But I’m not able to make these cuts.
This is a problem that i have for more then 2 years and never found a solution.
Is anyone knowing how to solve this?
Best regards,
Richard

Inventor will not provide a proper flat pattern in this case. I was surprised by how close it got, but the spherical corners simply are not flattenable by Inventor. They cannot be formed by a simple bend or roll operation, and these are the only types of sheet metal forming that can be flat patterned in Inventor.
A "100% solution" will have to be in a different software application.

Thank you.
Hopefully in the future there will be a solution for it within Inventor.
Again all who participated in this question thanks for your help.
Best regards,

Here is my shot at the sheet metal part.. hope this helps!
