Places base plates from the catalog on specified columns.
Create a generic system with the name to use for the base plate. Then, create a grid system with one elevation plane and the required number of X and Y planes to place the slab and any required openings. Create the base plates using Place Slabs Command in Structure. Change the material type to steel. After you model the base plates, including any necessary openings, copy the base plate to the catalog using the generic system as the root. See Copy to Catalog.
