Hi Larry,
Indeed, it seems Mark Madura gave up on this subject at DataCAD version 10, despite the general consensus by the users it was a vital key to maintain DataCAD's popularity, great having smart tools (some), even greater to know how to use them.
Video tutorials are the way forward on this, as it not only helps your target audience, but also adds promotion in for free.
I remember seeing some SketchUP video tutorials when SU was first released, needless to say I bought SU the following week.
This subject has been aired many times on the DC forum, but Mark Madura for whatever reason has not delivered, it beats me, as the cost to do this once you've bought your movie screen capture software must be negligible. Anyway the last time it was mentioned or should I say debated quite intensively to why there was still no new movies tutorials for the DC smarts & 3D in general was as recent when DCv14 was released.
Unfortunately it wasn't Mark Madura of DataCAD that stepped up to the plate,
but our friend Matthew Cockroft, you'll find some DC14 movie tutorials on the link below, I hope this helps:-

I recently bought SPIRIT Pro 2012 but haven't had that much time using it as yet. All I would say is that DC is still very intuitive to use for quick fire 2D drafting for construction plans etc compared to SPIRIT, but SPIRIT has had to change it's interface for it's turbo charged 3D drafting development, which can sometimes be confusing with the amount of extra menu's it has over DC. But even having said that, there are some very nice 2D tools that DC doesn't have. All in all I'll probably run both for the next year or so with the latest versions they have, but I reckon some enthusiasm/direction has been lost with DC of late, which puts SPIRIT Pro 2012 in my book with a more certain future with quicker development at this point in time.............DC smart roofs....still waiting..
Over & out,
Clayton.
