Those of you who might have some issues with SKP need to take a look at the UTUBE videos Nick Sonder has put up recently. His work says it all. From a developer as well as contractors standpoint - he's "nailed" his field. If you can't "build" from his work, then go home and change professions.
In addition, almost every other poster here has had something valuable to say. Do the "traditional (architectural) industry / practitioners" feel threatened, etc? No doubt. Can you imagine what AutoDesk and others have spent?
Having said that: The team of consultants / engineers / developers and builders we work with ? They could give a whit about "what' is used to create the end product. Millions of dollars are in play on these projects - literally (we're very, very lucky to have the work we have and, we try to appreciate it with frank, "humbleness" and, give thanks every single day).
In our work team, all manor programs are used, interfaced, etc. AutoCad does some great things and, quite quickly in the hands of talented (note "talented") user. Same for SolidWorks and several other programs mentioned. Frankly, it's all about the job and clear communications to the "end user" - be it design engineer, structural engineer, MEP folks, the client or whomever. We've never had a client with a seven-or-eight figure project say "how did you come up with that image or make those drawings?" They're busy, they want visuals, and most want them NOW. We've found that SKP delivers.
Too, we've received a number of project files from the "biggest and the (supposedly) best in the business). What we've had come across the threshold is truly, in some instances, unbelievably bad.
Remember: It's not the tool, it's the operator. Never forget that. If you're client has a problem with how you dig the ditch, hand him the shovel. Better yet, (if you can afford it) pass on that client; we've almost always found that, that type of client is trouble down the road. As for "balky" consultants that have too many "opinions." I flat out tell them: "they can always find their payslip elsewhere."
