And you should've opened a new thread for this...
Interesting feature. but i don't see that option in the meshes menu. FreeCAD 0.19

no mention is made of any special 'conda' or 'pybind' versions of FreeCAD at the documentation page. are they a requirement as others have mentioned?
Are using a self compiled version of freecad? If you compile yourself you need to enable this cmake-option: BUILD_FLAT_MESH:BOOL=ON I guess using boost.python instead of pybind11 shouldn't be an issue anymore.
I'm not using a self compiled version of freecad. I reckon compiling FreeCAD iwould be quite the non-trivial task though. Am I correct in that it is not enabled in the plain vanilla precompiled installer for Linux?

I'm just not seeing any evidence on the wiki page that it is an optional or inbuilt stock function. I simply navigated to the wiki via other references to that page in this current thread. Perhaps the - stroke symbol under "introduced in version" means that it has not yet been introduced? I'm getting flashbacks from playing text based adventure games :)

your terse answer still has some ambiguity. are you referring to the wiki or are you referring to the Mesh Workbench's Main Menu → Meshes menu?

If you'll forgive me, at this point it's not clear to me if you understand the problem. The problem is that I do not see such an option in 'Mesh Workbench → Main Menu → Meshes' and neither do I see on the wiki anything about whether that option requires special action or custom installation methods.

Also in this very thread I have read a few different points that this amazing feature needs to be custom installed, but I am not seeing consistency in those solutions, and maybe they are old already and the Unwrap Function is supposed to be bundled in the plain vanilla installer. I don't see the option in my lovely copy of FC, and the wiki again makes no special mention as to whether this feature exists natively or not. So at this point I should begin to take into account that this feature needs to be custom installed, and that information is not apparent if I use the navigatory 'Meshes → Unwrap Mesh' clue.

Maybe there is some kind of context sensitive toggle that turns the visibility of the option on and off, but I don't think so because FC seems to show enabled/disabled functions by graying out the icon if said function is not available for context reasons.

Both actually, It's quoted from the wiki and it's there in my FreeCAD version.

I've just updated to:

Code: Select all

OS: Ubuntu 20.04.3 LTS (ubuntu:GNOME/ubuntu)
Word size of FreeCAD: 64-bit
Version: 0.20.25844 (Git) AppImage
Build type: Release
Branch: master
Hash: 1b20118dfa3fb9f127f0e4fb122701f7fcdaa9fc
Python version: 3.9.7
Qt version: 5.12.9
Coin version: 4.0.0
OCC version: 7.5.2
Locale: English/United States (en_US)
[code]

I'm using the "normal" AppImage for 0.20 from here: https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds

The current one ist this: https://github.com/FreeCAD/FreeCAD-Bundle/releases/download/weekly-builds/FreeCAD_weekly-builds-25844-Linux-Conda_glibc2.12-x86_64.AppImage

Therefore nothing special regarding my installation. And since you're on Linux, it should be the same for you  :)

OK, that's really cool. I guess it isn't in version .19 and I need to upgrade, thank you.
