I have an architect who has a muliti-unit building that i linked in to ours, his is made up of 12 seperate revit files itself with typ units and such. One has a design option in it that when in the arch model it shows up but in my electrical file where it's linked in doesn't.....how do i turn off/on design options in my file when it's in the arch file that has the options? the option is just a set of walls in one unit set there for a possible hvc shaft.
