Sheetmetal welding unwinding

Axel_Kollmenter

Hello everyone,

I´ve tried to weld a part to a sheetmetal part. I created both (the sheetmetal part and the weldingpart) in one part-studio as 1 part (because it has to be one single part). Now I need an unfolded drawing but the extern feature isnt shown in the drawing. (Its because the sheet metal part was finished before I created the feature). How can I show the welded part to the sheetmetal part in the unfolded drawing?

The green marked has to be welded to the yellow marked.

If it´s not possible to combine these parts into 1 sheetmetal part, how am I suppost to show the complete part in one unfolding-drawing?

You can't do this in Onshape currently...
If you want to show where it goes you could "cheat" by having a sketched circle for part 2 on the drawing (and when looking at the flat head on you can't tell if it's 3D or not...)
But more importantly, in the "real world" you would bend the part first and then weld the Part2 afterwards so in this case I'm not sure why you would need to show part 2 on the flat view. It's a different story with formed feature etc that Onshape really needs to be able to show on flat patterns but it shouldn't be an issue here.

I agree with @dirk_van_der_vaart that you could make a part studio 2 to depict the 2 parts together.

Another way I would approach, is save a .dxf in an onshape tab with the exporting the bend lines option checked. In part studio 2, create a sketch by inserting the .dxf of the flat pattern to start creating the part. This way you have your bend lines in a sketch that you can show and dimension to in the drawing.

Something like this?

Yes, but I wanna see the "Part 2" on the unfolded drawing. (because it should be welded onto the sheet metal part.

Try using featurescript SM Fold, than you can cheat. Look at Part studio 2

Thank you all. I think I´ll try it like @bryan_lagrange .

You can insert the sheet metal flat part and part2 in an assembly and create a drawing of the assembly

But, I agree that that part is usually bended and then welded to the part2.

@emagdalenaC2i thats the best work around solution. thanks a lot!
