Setting the Origin
Each group has an origin indicated with a blue dot. The origin can be moved. Typically, you should place it located at the intersection of important walls or grids.
This origin can be used when creating a model group. Although most people create groups with the copy and paste tool, it can be placed from the Architecture tab.
Select a type. The placement will be based on the position of the group’s origin.
Groups in the Project Browser
There is a whole section of the project browser dedicated to groups. You can drag and drop a group from here to place a new instance.
You can also Edit a group from here by using the right-click menu. This is different from opening the group by selecting one in the model. This opens a different Revit file that you need to save.
