Problem creating a sheet metal box

Anonymous — Sat, 29 Jul 2017 05:19:00 GMT

Hello!

I did some experiment with the new sheet metal functions (preview) but i was not able to create the same box,

i created in Inventor... Maybe someone has a solution for me!

In Inventor i did the following workflow (see attached pictures):

1. Created a multi body sheet metal part

2. Created an assembly with two different sheet metal parts from the initial multi body part

Thanks! ... and sorry for the bad English 🙂

@Anonymous,

To create your design first mace your base and side flanges. Then create a sketch on one of the flange side faces. Next pick the flange tool and join the sketch to the edges by first picking the sketch and then the edges (hold alt/cmd to add additional edges). One thing to know is that to "join" the sketch does not have to touch the edge, but this is only for one edge. To do multiple edges, the sketch must touch the edge of the flange.

Hi Mike,

thank you for the reply!

But this is not the exact solution i was looking for.

This box is a real part that we manufacture in our company.

So the box is made of 3 separate sheet metal parts, wich are welded together.

In the attachement i send you the Inventor part file... from this master part i created 3 separate components (inventor function: create components).

I think the problem in Fusion is actually that it is not possible to "join" flanges from two different bodys or components.

Another problem i had in Fusion is that i was not able to create a hem...

Cheers

Manuel

Hi,

I'm not sure if I fully understand what you're trying to do, but I would recommend first creating a new component for each part rather than a new body. This allows you to move each component around. Also, it looks like you extruded a 45 degree cut on the corners. I've done something similar where I cut an angle, then unfolded the part to clean up the edges, then refolded. The problem with angled cuts is you need a 2D pattern to start the part with when you actually make it, so those edges will need to be made straight. Hopefully that helps!

Also, you can create a hem if you use a small bend radius and do 2 consecutive 90 degree bends and play around with the length of the bends to minimize the gap of the fold. Not a perfect solution, but works in most cases.

Is this what you were trying to achieve in fusion?
