# HeaderVariables Audit
|
|
|
|
`acadrust::document::HeaderVariables` — 232 total.
|
|
|
|
## Pass (no matching feature)
|
|
|
|
- **ISOLINES** — contour line count on curved surfaces (no curved
|
|
wireframe generator yet)
|
|
- **surface_u_density / surface_v_density / surface_type** — defaults
|
|
for SURFACE / REVSURF / EDGESURF commands (those commands don't
|
|
exist yet)
|
|
- **lens_length / camera_height / camera_display** — perspective
|
|
camera (no perspective viewport yet)
|
|
- **north_direction / latitude / longitude / timezone** — sun /
|
|
geographic data (no sun-shadow renderer)
|
|
- **LIMMIN/LIMMAX** — drawing limits (no bounded-grid mode)
|
|
- **INSBASE** — drawing's "save as block" anchor (no WBLOCK / "save
|
|
selection as block" flow)
|
|
|
|
### Remaining (intentionally not surfaced)
|
|
- ~70 `dim_*` defaults — render-time `DimStyle` reference is already
|
|
authoritative; these only seed a new DimStyle when a fresh DIMSTYLE
|
|
NEW flow is added.
|
|
- `*_control_handle`, `*_dict_handle` — internal table-navigation
|
|
handles; direct `document.layers` / `document.dim_styles` / etc.
|
|
accessors bypass them. acadrust read/write preserves them.
|
|
- AutoCAD UI prefs (`blip_mode`, `drag_mode`, `pick_style`, etc.) —
|
|
H7CAD has its own UI prefs and ignores AutoCAD's. Round-tripped.
