THE LIMITATION

705 methods = 705 individual capabilities

create sheet
place view
add dims
setup schedule
...

But a CD set isn't 705 commands.
It's a PROCESS with dependencies, logic, and decisions.

EXECUTION ENGINE

SPINE v0.1: PERMIT SET SKELETON

INPUT: A Revit model with rooms, walls, doors, windows

✓A0.01 - COVER SHEET (3D view)
✓A0.02 - GENERAL NOTES (Legends)
✓A1.01 - FIRST FLOOR PLAN (cropped)
✓A1.02 - SECOND FLOOR PLAN
✓A2.01 - ELEVATIONS (4x)
✓A5.01 - BUILDING SECTION

Under 3 minutes. Every time.

SPINE v0.2: ADAPTIVE WORKFLOW

IF project_type == "single_family":

sheets = [A001, A101, A201, A301, A401]

scale = "1/4\" = 1'-0\""

IF project_type == "multi_family":

sheets = [A001...A010, A101...A115, ...]

include_unit_plans = true

IF firm == "ARKY":

title_block = "ARKY - Title Block"

Same engine. Different outputs. Zero manual config.

MULTI-FIRM SUPPORT

A-X.XX nums
ARKY title
