Multiple Flange lengths with one flange operation?

I need flanges of varying lengths coming off the sides of a basic rectangular shape. What I have been doing up to this point is creating a flange loop operation with all flanges being the length of the longest flange I need and then using three extrude operations to remove the additional length from the other flanges. This is really slow, messy and seems like a terrible practice. Can someone suggest an alternative? I know I could create the four flanges separately and then go through the trouble of getting the corners and gaps right, but that doesn’t sound any better than what I have been doing. I think the fact that you can’t create multiple flange lengths in one operation is just about the silliest thing ever.

Thanks in advance.

I also use the chain selection for that type of panel as well, then I set mine to the shortest length and add FLAT flanges at 0 deg and the length I need.

I also use the rip for the relief...works well in our shop.

As you can see it flattens out nicely.

Can you post a picture?

I have not heard the term 'flange loop operation,' is this in Creo Parametric or is it another module?

Just my fancy way of saying I select all four sides in a single operation. (completing a loop)

The way you are trying to do all flanges at once, Creo is only going to give you 1 dimension. It's based on your selection.

Re: Multiple Flange lengths with one flange operation?

Yeah, it seems like a pretty weak program. Is this the best way to get properly mating flanges of various lengths?

Just like selecting multiple edges for a set of chamfers or rounds, they are all the same. The software grouping design would work the same with edges selected for a flange, they will use the same values.

Your best option is to do all 4 edges individually. A whole lot cleaner than creating extrudes to shorten the other flanges.

I agree, but the problem with that approach is that I've not yet managed to get the intersections of the flanges to come out as neatly.

Roughly what I need:

What happens when i do each flange separately:

How I've been doing it. Bad procedure, but better results:

Re: Multiple Flange lengths with one flange operation?

That looks like a good candidate for a product improvement. It surprises me that they went to all the trouble to create the reliefs and extensions but missed the utility of setting that length.

If you make a lot of these, then use one as a template to create new versions.
