I just started working with sheet metal in Inventor () and am currently modeling the baseplate of my circular saw as I intend to design a dust collection shroud for it.
For more information, please visit our website.
I've been able to model the part with a sketch; I formed a face and changed the gauge of the metal. So far so good. I went to bend up the edges with the flange tool and it seems I cannot flange the corners. The straight edges flange properly but the corners stay flat.
Obviously my design intent is incorrect and I am aware that I'm asking a question here that will likely resolve naturally as I continue my training, but I'd like to ask if there's a known good resource to learn this aspect of sheet metal forming.
I have tried fillets in the sketch and also experimenting with the flange and corner round tools and pretty much just end up with flat, un-flanged corners.
It also occurs to me that since this circular saw baseplate is formed by stamping, the only solution may require a boolean operation with a standard solid part.
Picture attached and thanks to anyone who can steer me in the right direction.

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.
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.
Roughly what I need:

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.
You can do flanges separately and still get the 'tidy' corners you get when you select them all at once.
Make the first flange, complete the feature and select the second edge, it will seem like it didn't work, but you need the select the 'offset' tab. Check the box 'Offset wall with respect to attachment edge' and select 'Add to part edge' from the drop down menu. This will increase the size of the 'planar' because we offset, be conscious of this. By choosing this method for the flanges by default Creo will assign a 'V notch' relief at the corner, if you would like ob-round or circular/square you will need to choose 'Corner Relief' in the Engineering tab and assign the desired relief. This will apply the chosen 'corner relief' to all corners.

Hey nice, I think that may be a little faster than what I've been doing. Also, I think your way may lead to less problems when the parts have to be adjusted in the future, you know how creo likes to lose edges. I appreciate you taking the time to post.
The need for various lengths on a chain selection seems like a no-brainer, I'm surprised we have to play games to achieve it.
