Sheetmetal flange. No bend relief

JACKW5PE3 — Tue, 09 May 2023 01:49:55 GMT

Part of the flange is not automatically creating relief. Instead, its cutting the whole edge back.

See attached screen shots and model.

Am I going about this correctly or is there a setting within the flange feature?

Order of operation is critical when doing sheet metal like this. To have the flanges meet and all work in one operation then you need to have all the faces they will be created on there to begin with.

Another option is to draw all the flanges where you want them to be and then use bend.

Extrusion 3 is not actually a flange either, it's a new body sitting on top. Unsure if that was intended?

One method is to get each flange in place but use offset to stop them overlapping. As so:

Then as long as they are on the exact same plane (use reference angles to make sure, even if they are 0.001deg off it will not work) you can use the Corner Seam.

Extrusion 3 cannot be a flange because it is a seperate body, and that body was created so I could do the flange command on 4 different bodies at the same time.

I am not sure what you are trying to convey with your attached pictures, the location where I need the bend relief is not a mitre joint.

Sorry, usually when I see this type of box the corners are mitered, which allows the features to work a little better.

PL-1 and PL-3 could be one part as far as I can see.

I would use "Face" instead of "Extrusion" to create these features.

You most likely need to use a work around to stop the Seam from cutting that back unintentionally. The sheet metal tools are a bit like that.

Using the "Width Extents" option, set the distance of the flanges first individually and then you can get around that issue.

I ended up just cutting the bend relief manually.

Thanks everyone for your help.
