I upload the file which was only a few clicks away from your model:andrigtmiller wrote: ↑Thu Oct 17, 2019 4:29 am The reason this is important, is because I need to create a 2D drawing, using the TechDraw workbench, and show the measurements for all the bend lines.
- start FreeCAD, load model, switch to SheetMetal
- select Unfold and delete it
- select Bend007 and make it visible
- select the bottom (from the inside)
- click "Flatten folded sheet metal object", check the boxes like this: - click ok, you should see this:

Re: Sheet metal workbench questions on unfold and bend lines
Okay, I followed your directions, and I get the same results. No bend lines, and I don't get the sketches generated either.
This is beyond frustrating, because it seems to work fine for everyone else.

You can try to reset the configuration with the button in the preferences. Another possibility is to delete your config files or to move them in case you want to restore them.
And you may try a recent 0.19 Appimage. Although easyw-fc reported that it works in 0.18 too, that wasn't explicitely for the bend lines.

Unfold successful

Traceback (most recent call last):

grp2 = Drawing.projectEx(co, norm)

So, there is an error in the Python script, which may explain why I don't get the bend lines.

Re: Sheet metal workbench questions on unfold and bend lines
Yes, this version of open cascade is very old, and the AppImage is using 7.3.0, so that is definitely the problem. I may switch to the AppImage for now, to get this done.easyw-fc wrote: ↑Fri Oct 18, 2019 4:36 pmThis is an error in the execution related to your version of OCCandrigtmiller wrote: ↑Fri Oct 18, 2019 3:23 pm Unfold successful

Thanks for helping with the report panel. I didn't think to do that.

Re: Sheet metal workbench questions on unfold and bend lines
Just wanted everyone who has helped out with this, that I have successfully gotten what I need by using the AppImage, instead of the Fedora 30 install. It works perfectly, and I opened a bug report against the Fedora distribution, since they are including such an old version of Open Cascade. The AppImage has 7.3.0, which is only one release behind the most current, which is 7.4.0, but the Fedora build is using 6.9.1.andrigtmiller wrote: ↑Sat Oct 19, 2019 12:18 amYes, this version of open cascade is very old, and the AppImage is using 7.3.0, so that is definitely the problem.
