Hi guys,

Is it possible to edit or create a family of cable trays in Revit. Im trying to re-create a manufactured family and have successfully created the fittings for it but im having trouble with the cable tray straights. Does anyone know how I can create a tray family that for example is 51mm x 51mm and keep that dimension as I use that family in the project, as well as incorporate the fittings I have created.

Id appreciate any help and assistance in this matter.
