I can't speak for it= 's auto router, but I picked up pcb-rnd last year to
start and complete a 12 PCB design. This is a new model of a BMS
interface we did a couple of years ago, but in a "shorter" Italtr= onic
DIN rail case. I chose pcb-rnd because of the 3D modelling capability
which was essential in this design. I needed to know where every nut and bolt went and spent quite some time with FreeCAD and an assembly
checking the clearances. There was a learning curve, but by the end I
was modelling my own parametric footprints in Tcl which plug directly
into pcb-rnd's library, and those precisely according to the data sheet= s
both footprint and OpenSCAD models. I really would never have got the
design finished without pcb-rnd, OpenSCAD and FreeCAD. We did what once would have been many many $Ks of work in this little workshop-office out the back of my place, on this average PC. Come December when the boards started to arrive from the factory - it all went together. Aside from a couple of tracks I'd swapped one one board and some other small errors = I
made like rotated tantalum caps. The CPU board was 3 layer and the Main board also and the rest are 2 layer. I'm happy send some snap shots if =
anyone wants to have a look.

Just my $0.02 worth.

Kind regards,
Scott
