### Line Style Conventions

Two distinct drafting conventions are present in this library:

**Convention A: Semantic Line Styles (highest quality)**
Used in: ROOF - EDGE DETAIL, ROOF - GUTTER DETAIL
- `INSULATION` -- wavy insulation representation
- `MEMBRANE` -- roof membrane lines
- `METAL` -- metal flashing/components
- `SUBSTRATE` -- structural substrate
- `BLOCKING` -- wood blocking
- `FASTENERS` -- nails, screws
- `ANCHORS` -- anchor bolts, clips
- `Line-1` / `Line-2` / `Line-3` -- weight hierarchy (heavy/medium/light)

**Convention B: Pen-Weight Line Styles**
Used in: ROOF EAVE DETAIL, ROOF TILE details
- `Pen 01` -- heaviest weight (profile lines)
- `Pen 03` -- medium weight (internal lines)
- `1` / `3` / `4` -- numeric pen weights
- `01-Line-Fine` / `02-Line-Very Thin` / `03-Line-Thin` -- descriptive weights
- `1_DASH B (x0.5)` -- hidden/dashed lines
- `Waterproofing Membrane` -- dedicated membrane style

**Recommendation for programmatic replication:** Convention A (semantic) is preferred for AI-driven detail generation because line style names carry material meaning, making automated element identification and modification possible.

## Duplicate/Variant Analysis

Several details exist in multiple versions. When selecting for replication:

| Detail | Variants | Recommended |
|--------|----------|-------------|
| Overflow Scupper | 4 files | ROOF_1-PLY OVERFLOW SCUPPER (membrane-specific) |
| Roof Drain | 3 files | ROOF_MOD BIT ROOF DRAIN (system-specific) |
| Equipment Stand | 2 files | Either (likely same content) |
| Lightning Protection | 2 files | Either (likely same content) |
| Cricket Diagram | 2 files | Either (likely same content) |
| Walkpad | 2 files | Either (likely same content) |
| Vent Boot | 2 files + plumbing vent | Pick based on roof type |
| Elevator WP | 2 files | ELEVATOR_WATERPROOFING DETAIL (corrected name) |
| Thru Flashing | 2 files | Either (likely same content) |
| Parapet Wall | 3 files | TYP. PARAPET WALL DETAIL W-INSULATION (most complete) |

## Notes for Programmatic Replication

1. **Scale mapping**: Details cluster around three scales:
   - 1/2" = 1'-0" for close-up flashings and edge conditions
   - 1/8" = 1'-0" for typical section details (tile, eave, wall sections)
   - 1/16" = 1'-0" for full wall sections
   - 1-1/2" = 1'-0" estimated for library .rvt files (standard BD Architect scale)

2. **Component vs. linework**: Two approaches coexist:
   - **Component-heavy** (wall sections, ROOF DETAIL-1): Use Revit detail components for materials
   - **Linework-heavy** (edge detail, gutter, valley): Draw with detail lines + filled regions
   - Most tile details use a hybrid approach

3. **Text annotation patterns**:
   - Material callouts use uppercase text
   - Dimension references (spacing, thickness) inline with callout
   - Slope indicators shown as rise/run triangles (e.g., "4 / 12")
   - "SEE STRUCTURAL" cross-references to other disciplines
   - NOA references for Florida hurricane zone compliance
