CAD plant layout before steel is cut

Roller pitch, lift stroke and linking modules are cheap to move on a drawing and expensive to rework after fabrication. A layout that ignores host interfaces or aisle rules leads to field cutting and schedule slip.

CAD is the working agreement among process flow, building constraints and equipment supply. Heights, clearances and section IDs on that drawing drive manufacturing and packing.

Building grid, column faces, door clearances, finished floor levels and any pits or mezzanines that affect roller height.

Host footprints with in-feed / out-feed elevations, service doors and recommended board flow direction from the OEM.

Target takt, mix of board sizes, packing discharge path and forklift or RGV routes that must stay clear.

Freeze transfer heights, curve radii, lift positions and electrical cabinet locations before releasing tube and frame cut lists.

If site survey and drawing disagree, reconcile first—do not fabricate to the optimistic dimension. Container packages and spare kits should map to the same frozen section IDs on that layout.
