Your article is pretty good and display your common sense for choosing the "right tool"
for the right job so to speak.
I also used TriSpective ver. 2.0 and it was fun, but also difficult to sketch and create things
precise for the most part back then, after all this years of developments and new releases
I suspect the product is more robust, but back then the Drafting was almost useless and
parts were disjoined or booleans didn't work like they should, plus sheetmetal didn't exist.
I've used about any cad out there and I think in this competitive market for being in the lead
companies like the one that owns IronCad need to offer they product cheaper to be in everybody's desks, at least if their names or brand are not easily known or recognized.
My advice for them is to sell their product at discounted prices and get in the door of every
small business, schools, etc.
By the way I visited IronCad website after being told that you could easily download a working demo, but that was not the case.
And what is happening to them has also happened to the old Cadkey, one of my first cad
tools, poor marketing and not keeping up with market trends(Parametrics, come to mind),
Assemblies, Sheetmetal, BOM, etc.
My 2 cents,
