Yeah. I searched a long time for an AutoCAD replacement and also ended up with this one. I'm always looking for FOSS (say Linux) apps and tried LibreCAD for example. it reads/writes DXF but it didn't work (feel) like AutoCAD. I'm a great fan of typing commands with keyboard and do the actual 'drawing' with the mouse/pointer.
Hmm this almost looks like a rant but what does a man need more than Line, Circle, Offset and Trim? maybe DIM in a while...
Designing is different thing than drawing. AC is drawing application and I don't need even Offset or Trim and not mouse. Arrow keys are enough for me.
I have done 32 years CAEE program for industrial automation.
Now I'm in pension age and my next hobby is do it with Java. Then after it works also in Linux and Mac.
Design starts with "database" manually working as well with CAEE.
We must know every devices and other parameters before work out start construction drawings!
Then, drag and drop equipment from database to construction and field devices cabeling. Symbol files -construction, circuit diagram etc.- are linked in d-base record.
No, we have Cable list, List of field devices and Equipment lists for boxes and cubicles. Eq-lists are coming from construction drawing d-base links.
Construction drawing (as well circuit diagram) is like HTML page with links, not 'stupid' CAD-drawing, appearance is the same.
Last step of designing is diagrams.
Drag and drop from d-base again but x-ref-d-base becourse they are allready designed in constructions and field. Or give only position when application find out it's data record etc...
Application x-ref verifys that every device are in some "construction" and some "diagram" and makes "Error report". It takes few seconds, try do it manually!
