How to add new Revit models downloaded from GABCAD to my current revit projects? I am using Revit 2013
If is a family which you want to import, then you need to open both projects (yours and the grabed one) then just copy the family which you want to copy and paste it in the other projects.
If you talk about buildings'models, then I would suggest you to link them.
Hi, open the Revit model as normal, right click the family catagree, save as new file ,, this way you will be able to save the entire family cat in that model to a folder which will help you amount your own families liberary and be able to load from there
hope this tip helps
