Integrating OpenSCAD with A Drawing Based Modeler

I love OpenSCAD.  I've been using it for about 10 months now, and I can say
that I'm probably past kindergarten and first grade and I am at about 2nd
grade level.  But...

Frustrated with some of the limitations of OpenSCAD, (specifically, the
convoluted steps needed to make chamfers and fillets, and the inability to
generate mechanical drawings) I decided to take a look at drawing based CAD
programs, finally deciding to dive into FreeCAD since its documentation
promised integration.  I'm about 8 hours in and have here are a couple of
observations:

1.The learning curve is steep, very steep. Even very simple parts can turn
into disasters if one does not pay attention to the Topological Naming
Problem. And when one starts to use parametric modelling, things get clumsy
and tedious.

  1. The documented integration via the OpenSCAD workbench...  doesn't work.
    My hope was to do 99% of a model design in OpenSCAD and then drop it into
    FreeCAD for the fillets and chamfers. However, I tried to import several
    non-trivial OpenSCAD models, none of them were even close.

So, my question today is: Are there other drawing-based programs that I
should look at?  My only requirements are that they cannot be cloud-based,
should be relatively inexpensive (<$500), and should run on Linux.

Thanks!

FreeCAD drove me nuts too, so I gave up on it.

The fillet/chamfer issue is the #1 reason I use anything other than
OpenSCAD. (The #2 reason is that there are times when I really do need a
smooth curve on a large part, and OpenSCAD's rendering speed on these is
painful.)

That said, I do use cloud-based solutions when I'm not in OpenSCAD. I tried
Alibre but didn't like it, and it won't run under WINE anyhow.

But I've got my eyes open for any suggestions you get.
