I have a group of objects (buildings) in one blend file and i’ve grouped them. I have another blend file of a site plan and i’ve appended the group into that blend file. Now i want to position the group of objects by snapping to an exact location on the site plan. How do i do this. When i try, the one object in the group that i set as the point snaps to the cursor but the rest of the objects in the group just disappear.
