Thanks Quirk, RSD....I appreciate all of the info regarding app's that I can get.
Again, my buggaboo at present regards the lack of "Professional Level" software that runs under Linux for high end use.
The print profession, almost categorically, wants MAC files generated from a MAC. After many years (and Adobe fixing a lot of bugs) some of them are finally able to work efficiently with PC generated high-res print-ready graphics. Quark is another issue altogether, but having been an early entry into the "professional" print arena, it is still almost a requirement despite its translation, import/export and file issues.
Engineering/Architectural design software is dominated by Autocad and Microstation with a few other major players like Catia, Pro-E, etc. standing in the wings. The costs are high, but not necessarily prohibitive for the MAC and PC versions of the first two. However, after many years, they have a fixed place regarding 3-D design capabilities, file sharing and compatability with third party CNC and modeling packages that still does not exist in a Linux desktop application.
As noted earlier, Linux versions of the "high end stuff" have not yet been ported by Autodesk, Adobe, etc. for several reasons (mostly market economics). That is what I am whining so much about. Having a Linux platform and no professional software to run on it is like having a nitro-powered race car in a world that only sells regular gasoline.
Have a great day...
