Woodworking Box unfolding - How to

[Anonymous]

Hello everyone, I am looking for a way to unfold a specific part. I know it is doable in real life, so I assume Inventor is able to do it too, but I can't seem to find a way to make it work. Please help.

I tried making an unfolded profile of the part, then adjusting the bend radius to .001 so it would make a .001 inside radius and then a .002 outside radius, but it doesn't work like that according to Inventor logic, it makes it .751, so then I tried manual radius of .001 and .002, still wont work. Then I tried drawing lines on a back face and use the unfold function... still not working. And yes, I used the offset function with a .001 offset to make sure the part wouldn't "break" from what I know of Inventor's behaviour. I tried various offsets and radii too, like .100 offsets with adjusted radius, still wouldn't work.

I would appreciate if somebody could link me a file that works.

You wanted it?

Are you trying to make a v-groove bend?

Inventor's sheetmetal is limited to parts with uniform thickness.

You might try some of the workarounds in the following posts

In this version, which I proposed and used, it is not necessary to imitate a V-shaped groove, it is only necessary to draw the shape of the groove with the shape of the correct - a blunt cutter. Use the bent part in the assembly, and a copy with the suppressed bend for drawings and for transfer to the CNS

You are using a newer version than me so unfortunately I can't look at your steps properly, but I should be able to replicate it pretty easily. I didn't know there was yet another bend function like this (that's like the 3rd or something Inventor has !)

Thank you very much!

Sorry for the long delay, had internet issues. 2016.

for 2016 I have no opportunity to make a sample. If you do not get what you want yourself. Write I'll make at least a video

Would 2019 be better? I could read that version,
