Hi Josef,

I did hydraulics, ladder diagrams for PLC and other stuff with gschem ;-)

Entering the schematics for control cabinets should be doable with 
gschem although you would almost have to start from scratch with the 
symbols required.

Either power distribution (3 phase 400V AC), or 24 V DC control using 
either old fashioned relay technology or programmable logic controllers, 
or field loops can be done ... it's just schematic entry and generation 
of portable document files for design, verification, managing 
sub-contractors, commissioning and maintenance.

Even the layout and placement drawings of cabinets can be done with gschem.

The entire life cycle can be covered ... that is, if everybody thinks 
this FOSS solution gives the lowest Total Cost of Ownership.

Now the hard parts lie in what "smart thinking" you want gnetlist or 
scripts (python) to do for post-processing:

- generation of cable lists,
- generation of cable to terminals in junction boxes,
- material take off,
- pricing of MTO,
- cost calculation of manhours,
- planning of duration of works,
- etc.

Best advice I can give you is to start small ... try one or two pages of 
every document type you foresee you will need before jumping into the 
deep ;-)

That will give an idea of the amount of effort required for the 
schematic entry part ... and then for post-processing .... YMMV ;-)

Kind regards,

Bert Timmerman.
