Discussions about any other product with no dedicated forum - MEP Modeler, ARCHICAD Goodies, 3rd-party Add-Ons, operating systems, products of other vendors, etc. (Example: Which Add-On is the best for creating special Stairs?)
It sure seems possible, and such an obvious need.
What you can to is make a set of interactive schedules for reporting the input data in the same order you need it for filling out your Manual J, Manual D, Manual S, or ResCheck, Comcheck, apps.
I doubt it. They probably just use a .pdf. ? I use ResCheck from time to time and I have interactive schedules that report the data I need to fill out that app - in the same order as the app - so it is very quick to enter the numbers.
