Flat patterns not showing bend relief notches

gcross — Thu, 26 Sep 2024 20:05:39 GMT

Our sheet metal flat patterns are not showing the bend relief notches that are in the formed 3D .ipt part models (see attached images). This had not been a problem (didn't notice it) until a new supplier made the parts without the bend relief per the flat pattern.

I tried changing the Flange/Bend settings from default to round & square but the bend relief never changed in the model or flat pattern.

Is there a setting I'm missing to make the notches appear in the flat pattern?

Check settings in corner tab in dialog box.

You need to set the 3 corner bend relief to suit your outcome.

Go in to the Sheet Metal Defaults dialog and then pick the "Edit Sheetmetal Rule" (Yellow pencil).

Go the Corner Tab in the Styles and Standard editor window.

Pick the 3 Bend Intersection Relief shape to change to the option you require.

Hope this helps

That did it!
I selected "No replacement" under the Style & Standard Editor/Sheet Metal Rule/Defaults/Corner Tab & the flat pattern now shows a notch at each bend location more consistent with what the models shows.

Odd that picking the same setting while editing the Flange feature/ Corner tab/3 Bend Relief Shape does not affect the flat pattern at all.

Setting changes in the corner tab under the Flange feature in the browser have no effect on my flat pattern.
Looks like it must be done in the Styles Editor/Sheet Metal Rule/Corner for it to take affect on the flat pattern.
