Hello,
I need a help for creating a beam with a rectangle variable section. I want to give the start section, bi x hi and the final section, bf x hf and it automatically creates the beam with those descriptions.
I would start by opening one of the out of the box beams...the HSS is probably a good start, save it to your custom library with a new name. Delete the sweep in there and the existing reference planes. You can rename the existing H and B parameters or create new ones....if you want them to schedule then make them shared.
Create a Blended Sweep and draw the profiles and assign an equality parameter first, then the H or B parameter. Edit the other end and do the same with those parameters.
I did a simple example which I attached....Revit 2017
