New user: Question on unfold 3d to sheetmetal

Post by Metalika »

Good day.
I have never needed freecad until now....tried it several times but now its the time :)

I downloaded the newest version but would not install so back to 0.19.
I need this for the parametrics and sheetmetal. (cfd hopefully and motion also)

I draw all my 3d stuff in Moi3d.

Now my question is ...if I have a 3d shape (pic attached) and I would like to unfold and then make it into a sheetmetal part.
What is the best way to accomplish this in Freecad?

Thank you in advance!

Hmm...why wouldn't it install? What was the issue?

it is possible to make this object with sheetmetal, but on 2 conditions: the angles must have compatible radii, the box must have a correctly chosen open face

I don't know if you've checked the wiki or not, but the commands Make Relief, Make Junction, and Make Bend seem to be what you're looking for.

It may not work on a part quite like that, but it might be worth a shot.
Hopefully this helps!

@ drmarco when installing it just seems to hang about mid way...I tried 2 times and then removed form my pc.

@papyblaise and danvie...

I am trying to understand before I deep dive into Freecad what would the best thing to do or what is possible.
I have attached the same model where indicated in orange should bend, red cut, marked black dont exist and lets say it is hollow.

Question 1: If it was not hollow ...could I import from Moi3d as a 3d model to unfold in Freecad and then make it into a sheetmetal part?

Question 2: if imported as a hollow item ...so constructed from several planes....can this be unfolded in Freecad and then be converted into a sheetmetal part?

Question 3: Or try to unfold it in Moi3d , import into Freecad and then convert to a sheetmetal part?

I hope these questions makes sense...

Thanks to all!

Many here use mesh as well. Me, and just my opinion I prefer triangulation. An indepth discussion is viewtopic.php?p=611276#p611276

My 0,05 €.

Tools from @danvie post have problems to work due to non-perpendicular faces (?).

This is great...now I know the direction to take.

One of my designs that I have I need to make sure it works before cutting the metal it in real life.

Thank you for your time!

I just have one thing to say - good luck bending that thing with anything but a hammer and chisel
