Reference plans help match real venue structure, but the source is evidence—not automatic sellable inventory. Seat labels, counts, accessibility, and commercial meaning still require authoritative confirmation.
Choose the right import path
Private raster trace
Upload PNG, JPEG, or WebP as an authoring layer. Position, crop, rotate, scale, calibrate, lock, and hide it while drawing.
PDF page
Select one page from a PDF up to 15 MB and 100 pages. SeatLayer rasterizes that page into the private trace layer.
Editable SVG/DXF
Import supported sanitized primitives as ordinary editable Shape objects
in one undoable operation.
Buyer background
Add an independent URL-based aesthetic layer when buyers should see venue artwork behind inventory.
Raster/PDF tracing workflow
Upload and select evidence
For a PDF, choose the page that contains the authoritative floor plan. Keep separate supplemental label or inventory sources distinct.
Calibrate
Mark two known points and enter their real distance so spacing, row gaps, and section capacity can use a physical scale.
Align and lock
Set crop, width, rotation, opacity, and layer placement. Lock the reference before detailed authoring.
Author semantic geometry
Draw floors, sections, aisles, rows, tables, booths, GA, shapes, and labels. Use the reference as visual evidence, not a source of unverified identity.
Compare and review
Toggle the source, render buyer previews, check alignment, and confirm capacity/labels against authoritative venue records.
Vector import boundary
SVG and ASCII DXF pass through a bounded parser. Supported primitives become editable shapes; arbitrary scripts, external URLs/resources, embedded objects, full CAD fidelity, and SVG export are outside the contract.
Inspect imported layers for:
- unexpected scale or units;
- duplicated or microscopic primitives;
- fills that hide bookable geometry;
- text that should become semantic labels; and
- decorative lines that should not create inventory.
Source-of-truth policy
| Fact | Can image alone authorize it? | Required confirmation |
|---|---|---|
| Approximate section boundary | Evidence only | Visual/human review |
| Seat count | No | Venue inventory or explicit owner confirmation |
| Seat label | No | Authoritative labeling plan |
| Accessibility | No | Venue/operator confirmation |
| Category and price | No | Commercial configuration |
| Aisle/exit context | Evidence only | Safety/venue review |
Agent-assisted workflow
The remote Designer MCP can let an authorized external agent inspect private overview/tile evidence, submit semantic regions, invoke deterministic compilers, render diffs, and prepare revision-bound review evidence.
It does not provide a hosted vision model, and it cannot turn uncertain pixels into approved inventory by itself. See Designer MCP.
Verification checklist
- The correct source and PDF page are selected.
- Physical scale is calibrated from a known distance.
- Private evidence is distinct from buyer presentation.
- Every seat count and label has an authoritative source.
- Accessibility and pricing are explicitly confirmed.
- Vector imports contain only intended editable primitives.
- Buyer preview never exposes the private reference.
- Comparison and validation pass on every floor.
