When doing some testing about how to best bring a GC model (3D-DWG format) into a Revit file we came to the following colcusions:
Essentially we had two option:
DWG IMPORT DIRECTLY INTO PROJECT
- It is treated as one complete object. Elements cannot be selected individually
- No massing can be applied
- Less control when trying to dimension to it.
DWG> MASSING FAMILY> INTO PROJECT
Loaded into Project file
- Makes reloading easier and accurate since origin point and offsets are already defined. Bring dwg in the same place in family. Then okay.
- Can apply massing to the elements, but it can be a bit tricky due to the complex nature of some forms.
- When form is changed, the massing in Revit disassociates since the reference in no longer the same. (Linking not an option in Revit family files) Massing elements can be re-associated to dwg.
- Updates will drop dimension
- Layers can be switched off in VG to create various set-out drawings – like structural versus glazing etc.
