Interesting poll, but my job is not listed.....Structural Engineer
but I'll stick a vote in Construction.
Working for myself I've started using DoubleCad as I can't afford ACAD, simple as that. I use it to produce G.A's, fabrication drawings, surveys etc to supplement my calculations and it performs well enough, sometimes I have minor problems, but I get over them.
I can also work on imported ACAD drawings easy enough and use Format Painter to make all notes, dims etc consistent. I did struggle at the start, even though I'm reasonably competent on Acad, however I don't like the latest versions of Acad at all. Printing was a bit of a challenge, but all ok now.
Rob, I tried DesignCad, bought a copy,read through the manual, but just cannot get to grips with the 3D. I find myself using Sketchup and importing SKP files when I need basic 3D structures, wish I could get into Designcad though.
