Drafting Automation

Firms have automated drafting for decades. LISP routines, script files, dynamic blocks, sheet set templates, and attribute extraction all exist because drafters spend hours on the same operations: renumbering tags, updating title blocks, swapping backgrounds, and redrawing typicals. Rule-based automation is fast and predictable, but it only covers work someone took the time to encode, and it breaks when inputs vary, for example when an architect's new background uses different layer names. AI-based drafting automation handles the variation that scripts cannot. It reads an unfamiliar background, interprets a hand markup, or lays out devices in a room the script was never written for. The two approaches work well together: firm templates and standards define what correct output looks like, and AI does the judgment-heavy placement inside those rules. Any automation still needs QA, because a fast error repeats across every sheet it touches. Nomic automates drafting inside your firm's standards. Nomic works in CAD on its own computer, saves real DWG files to the project in your layers, blocks, and title blocks, and checks each drawing against the code edition you name and the source documents before your licensed professionals review and stamp it.

A script renames layers to the firm standard, then AI places receptacles in rooms the script cannot interpret.. Title blocks on 40 sheets are updated with a new issue date and revision number in one pass.. A background swap from the architect's 50% CD set to the 90% set is handled across every MEP sheet and each shifted device is flagged.
