This Is Big News In The Future Of Bim/cad As We Know It. in General Q & A Posted May 7, 2015 Are your customers really going to choke down the costs associated with fully detailed MEP plans when the local residential code authority doesn't require them? I would love to see a residential level ductwork tool so that I can give the HVAC guys my view before they start to build soffits everywhere. I wouldn't mind if it could do basic Manual J calculations either. And while I'm at it it would be great to have simple load/span tables as well. I hope Chief continues to focus on making their program the most versatile residential tool on the market, it will take them a long way for the foreseeable future. The commercial race is over. If I was in marketing at Chief I would interview as many of their architect clients as possible to find out what they really need in terms of the occasional restaurant/store, and see if that can be accommodated (curtain walls I would assume) and then leave it at that.
