I know, why not use your calculator or the duct design calculator (spinning template)...since DD3D doesn't have a duct size calculator.

Does anyone have a routine that does duct sizing? I found one a month ago that was suppose to pop-up a dialog box, but couldn't get it to work. Hopefully the routine can do rectangular and round by size input and friction loss/cfm. Oval and another option of CFM/velocity is optional, but would be nice.

Have you checked out the duct sizer from McQuay?

Hmm that didn't come up in my search. Close, but not quite what I am looking for. I would also want the program to convert duct size to/from round, rectangular, & oval. Example: have 12 round and input a rectangular edge and returns the other side.
