So I enabled/created my work-sets, created my central, and local, not to mention link in the other disciplines. Everything came in perfect when I linked in origin to origin. I go to an elevation view and my levels are at 0'-0" and 10'-0" which I know are default from my project template. The architect is at a 100'-0". What is the best method/ practice for aligining my levels/grids. It is my assumption that it isnt as as simple as merely moving my levels (the host) to the elevation of the linked model (architect. mech) or vice versa. Was hoping to get the best practice for me (the host) to aquire the coordinates to the arch (linked model) as well as move the levels to the proper postion. I appreciate any help you can offer. Thanks in advance.
