I have problem, because in \mod\ folder I don't have sheet metal (?). I am installing by addon menager but I am not sure is it up to date. Why I don't have this module in \mod\ directory?

Re: help on sheet metal script
open any macro, you can see your macro path. in the same folder, mod folder also there.

Hi jaisejames,
The new system looks as if the metal is twisted. old system looked clean.
old system: new system: and also, when you set unfold to true you get:

Re: help on sheet metal script
Hi everyone,
first thanks for your great improvements on sheetmetal WB which is really convenient and reliable to get accurate unfolded metal parts. That's really cool
I have posted some threads about sheet metal, namely here: https://forum.freecadweb.org/search.php ... 5&sr=posts
I would like to post a tutorial concerning the unfolding of a non sheet metal 3D cad model, similar to the Jaisejames's tutorial https://forum.freecadweb.org/search.php ... 9&sr=posts
But the workflow I'm using fails at the end because of a limitation or maybe a bug concerning the unfolding function.
Please find here the FC file.
The problem: the part is made from a shell by using Part->3D Offset (fill option). I get the "Offset" feature, no any problem to unfold it.
But if I add some cosmetic Part->Fillet(s) on perimeter edges (I don't mean about bend edges) then I can't unfold the "Fillet001" feature and I get the error message.
That's sad because by using Part design workflow and part design fillets on a sheet metal base there is no any trouble to unfold.
Unfolding problem seems linked to offset + perimeter fillet (other 3D parts from boolean or extruded close sketch or part design, etc... are easy to unfold, even with perimeter fillets)
So, please could you guys (@shaise @jaisejames ?) allow the use of Part-fillet feature on sheet metal perimeter?

Re: help on sheet metal script
The problem related to Unfolding tool. Unfolding tool by Ulrich Brammer @ulrich1a. I don't have much idea.
Re: help on sheet metal script
Thanks for your reply, you're right it's about unfoldind so i should ping Ulrich. Tell me if I have to open another topic, I wouln't hijack this thread.
BTS: thanks for this great unfolding feature !
Please Ulrich, see my message above https://forum.freecadweb.org/search.php ... 5&sr=postsulrich1a wrote:"ping"

It's lame but currently you need to go an extra step in order to 'ping' a forum user. @ulrich1a's user_id needs to be included as such

Re: help on sheet metal script
Thanks for the tip
Thanks to have checked geometry, I didn't think to do that. However I can't remove the peripheral fillets after an offset because I need them in my workflow.
I have found the error: it's relevant with the offset direction! While offset outward no problem, error in geometry occures while offset inside the shell...
Hence there is a problem concerning Z shaped sheet metal because this kind of parts is offseted in both direction and will fail systematicaly.
So I assume this problem concerns Part WB and not sheetmetal WB. So...any help is welcome. Does it need a bug report?
Edit: Thanks to Maurice:
I have fixed the fc file, my bad: the peripheral fillet was on a wrong edge. Picture below is updated as well. Anyway, the problem remains.
