8 way corner radius

Yashasvi23481 — Thu, 04 Sep 2025 00:20:37 GMT

Hi All,

I am using 2025 Inventor. I have a strange request from client and this is for modelling point of view as they want to put this model for their online catalogue. In reality, side walls will be welded and rounded off. But for modelling purpose, it has to be in 1 piece.

I have done derived part but not sure we can get this in 1 profile (single plate)? Can any1 give it a shot. Plate thickness is 1.5mm and overall dim is 400Lx400Wx300H. I have done this in 2 sections or 4 sections but not in 1 go.

Other alternate option is, to draw sharp edge rect with offset of 1.5mm and apply flange from 4 corners at the bottom and later on do fillet option for 4 wall corners. But then you will have gap in 4 corners. Not sure which is better way to do this.

So main question is, can we do sheet metal of 1.5mm wrapped around this skeleton or derived part in single go?

Thanks in advance.

Yash

Hi All,

Further to my earlier post, i gave a shot in doing the derived part but i am not sure what i am missing here. See below. Why cant i select corner radius on 4 sides. How can i continue selecting faces to join them?

Regards,

Yash

You did not attach a derived file.

Hi @kacper.suchomski,

A3 internal skeleton.ipt is derived part attached in first message.

No, this is a new file with no connection to the weldment.

I'm still not clear on what is needed-- to make a nice-looking model for the catalog, or to make a sheet metal model that can be flattened, made from one sheet? You mentioned that in reality the corners will be welded, then rounded off. But the radii in the photo are much too large for such treatment, except for the flange around the top edge. That sink in the photo is a deep-drawn piece, with the flange welded on afterwards, I expect.

If it's a finished part you're looking for, here is my quick attempt, made from the model you posted (Inventor 2024 format):

Hi! Though the part is a Sheet Metal part in real life, it isn't the kind of Sheet Metal part Inventor Sheet Metal environment is targeting. The part is a stamped part. There aren't any unfoldable bends. I guess you may use Thicken command to get the desirable body.

Many thanks!

Thank you all for the help. thickened command help me join the side faces.

Hi Kacper,

This is derived part i could get using thickened. But i couldnt flatten the other 2 flaps.
