How would you model this sheet metal box?

[ccec_ireland]

I've modelled this box, and there must be a better sequence to follow than the one I used. How would you do it? What's the best route to get to this finished shape with better reliefs?

1. I started with the front and the angled top faces created as a contour flange from an initial sketch.

2. I added the top vertical flange off the end

3. I added flanges off of the sides

4. I sketched in and faced the triangles on top of the side flanges to match the angled top flange

5. I added flanges to the end of those side flanges

6. I sketched and faced the extra length of the final flanges onto them.

The bend reliefs are all wonky and I'm not sure how to fix that. Inventor is unable to unfold this to edit it flat.

Instead of face, use corner seam with 0.01 gap.

Actually complete the contour:

Yes, I certainly could have done that. I don't think that would help the awkward reliefs on the sides though. Any thoughts on improving those?

Missed the corner seam post. That is the tool I was missing. Thank you.

In my opinion, all sheet metal containers with slopes are most convenient for surface modeling.

Hi! Here is another approach based on an imported body.

Many thanks!

That's very cool. Thank you.
