still some troubles with FEM WB

or with Path WB

You can also check if Netgen maesher is available from "Create mesh from shape..." in the Mesh design WB.
Do you know if "BUILD_FEM_NETGEN" set in CMake for the build?
If so do you know if your NetGen is linked against the same version of OCC as FreeCAD?

if I see your point (maybe I misunderstand), I would say it's not set:
if I try to compile 0.19 with

Netgen seems not enabled by default, however I don't know how 0.18.4 from repository was compiled...

I think its here: https://salsa.debian.org/science-team/f ... /rules#L15
If thats correct you need the netgen and netgen-headers packages https://salsa.debian.org/science-team/f ... rol#L49-50

Also please try 0.19, as it's obviously much more improved.
I try to compile but no success:

First, when installing dependancies, 2 stuffs were missing:

How about FEM and Path?
Netgen is a PITA. What Ubuntu is your system based on?

There is a pyside2 QT5 clash on some systems. See here: https://forum.freecadweb.org/viewtopic. ... 20#p395462

libboost-signals-dev is not in Ubuntu 20.04 but it doesn't seem to be needed if you use -DUSE_PYBIND11=ON in your CMake call.
Like my FreeCAD work? I'd appreciate any level of support via Patreon, Liberapay, or PayPal! Read more about what I do at my blog.
