See attached SW2016 file. why is the surface shown below coming out different on sketched bend 4 than on sketched bend 5? they are both set back .1mm with their bend radius and bend position the same?

The first bend is still on the straight portion of the part whereas the second bend falls on the angled portion of the part.
But why? If you look at the underlying sketches for each of the bends you'll see the sketch line is set back the same on both bends. (.1 m)
I actually played with the order in which I make the bends and when I make those 2 bends 1st they both come out looking like the one shown in my picture. I'm thinking now they both should have looked this way and the first one is the anomaly not the 2nd
I agree that they should both look like the second bend but I am not sure what is causing this.
I never lay out parts this way, we design for the finished shape and then let Solidworks determine the flat pattern. You are going to need to know the bend deduction for each bend this way so that you get the flat layout the correct length and also bend locations in the correct spots.
If I get some time I will model it the other way to show you.
Thank You Casey. I did just as you said and it came out much better. With all the sheet metal tools it was still easier for me to model the part and use "Convert-Solid1" to arrive at the flattened pattern. The convert solid feature automatically created these "RoundBend" features. I looked for them in the software but could not find them anywhere. does anyone know what they are?
The round bend features are added by using the convert to sheet metal feature. I would suggest starting the part out as sheet metal from the start and using the sheet metal features to add what you are needing. I just mocked up what I think you are wanting but didn't include all the features.
I do have a couple questions. Are you making this part out of 6061 annealed aluminum? Are you going to be able to get that tight of a radius on the bends? We typically use 5052-H32 when bending aluminum parts if we are needing a tighter bend, and by tighter, I mean that the bend radius is closer to the material thickness. We always have trouble with 6061-T6 cracking along the bends.
Hope this helps.
Hi Casey, The part will actually be made of 4 mm coroplast which is corrugated PP. Just trying to get something to send to the box maker for quote. The bend lines will actually be score lines so the bend will probably be sharper than depicted.
