Hi I'm the current maintainer of dxf2elmt, although I haven't had as much time to work on it as I would like recently.
A couple of notes, dxf2elmt should be preferred over dxftoelmt, it's much more up to date, and handles dxf features that dxftoelmt doesn't.
In regards to the message "cannot find cfg" I'm can't think of anything at the moment that would give that error. dxf2elmt doesn't even have a config file, it has a set of defaults options that can be changed using command line parameters. When launched from QElectrotech it pretty much just uses the defaults.
Do you know what version of dxf2elmt you are using? You should be able to run
to find out.
The latest release is v0.6.1 and can be found at https://github.com/Vadoola/dxf2elmt/releases, although I only have precompiled version of x86-64 Windows for that release. I guess the other question is where did you get dxf2elmt from? Are you compiling it yourself? Since I don't have an ARM compatible Mac version up in the releases?
I also don't have a Mac of any sort, let alone with an M chip to really test against. I've been wanting to try and get the Github Actions working properly so it will compile the correct version for different OSs.
If you can let me know what version you are running, and if there are any logs that are being created I can see if I can dig a bit deeper.
