This toolkit has two sets of tools. Drafting and Parameters.
Drafting is a set of tools that will empower any MEP drafter to do all their drawings from a 3D view. This keeps them in the know about potential coordination issues, stopping any clashes before they even happen.
Parameter tools help you stay in touch with your parameters, automatically summing any numeric parameter value, as well as quickly and easily adding parameters to families that appear in a schedule.
