I'm new to using C3D. In land desktop, for a road design project, typically I would have a topo drawing for existing conditions, a drawing with the road design linework, another drawing with proposed storm, water, sewer, and then maybe another drawing with other utilities that I others would design (such as gas, power, telephone). I would xref all the various drawings into "plotsheets" where I would have our titleblock.

While working on the design, I would have the various drawing xref'd. With LDD being data being in a database, I could create alignments and then no matter what drawing I was in, I could draw linework based on STA/Offset or inquire a point to check on STA/OFFSET. With C3D, how do I draw linework based on STA/OFFSET unless I'm in the drawing with the alignment linework? Do I just need to include the alignments in any of the various drawings I want to be xref's? What changes in procedure should I be looking into for the switch to C3D?
