Interface SVGExportOptions

Optional background <rect> fill. When set, emits a rectangle the size of the viewBox before any geometry, so the output isn't transparent. [r, g, b] triplet (channels in [0, 1]).

When true, consecutive line-segment pairs that share an endpoint coalesce into a single <polyline>. Smaller output

• faster browser parse for drawings with long connected runs; adds a coalescing pass. Default false — emits one <line> per segment for simpler round-tripping through other tools.

Fallback stroke width applied when a mesh / material doesn't declare one. Default 0.5.

Optional override for fill colour. When set, every emitted polygon (triangle) uses this colour regardless of per-mesh colour. Set to "none" (the string) to suppress fills entirely and emit triangles as their outlines only.

When true (default), the projected Y axis is negated so the drawing reads right-way-up — world +Y appears at the TOP of the SVG, matching how a viewer would expect to see it. Pass false to honour SVG's native +Y-down convention without flipping (typical when the source scene is already Y-down).

Optional explicit height attribute. See width.

Padding (in scene units, pre-scale) around the SceneModel's AABB when computing the SVG viewBox. Default 5. Avoids edge clipping when strokes have visible width.

Which world plane the SceneModel is projected onto when flattening to 2D. SVG is inherently 2D so one world axis has to be dropped; the choice depends on which way "up" points in your scene:

• "XY" (default) — drop world Z. Right for the typical floor-plan / drawing case where Z is small or always 0.
• "XZ" — drop world Y. Right for Y-up architectural scenes where you want a plan view from above.
• "YZ" — drop world X. Right for elevations / side views.

The chosen plane's first axis maps to SVG X, the second maps to SVG Y (with optional flipY).

When true (default), wraps the geometry inside a <g stroke-linecap="round" stroke-linejoin="round"> so all strokes inherit those properties without being repeated on every element.

Multiplier from scene units into SVG user-space units. Default 1. For a millimetre scene meant to print 1:1 to user-units, leave 1; to render at 1:50 use 0.02.

Optional override for stroke colour. When set, every emitted line / polygon outline uses this colour regardless of per-mesh / per-material colour.

Multiplier from SceneMaterial.lineWidth (which the SDK treats as pixel units) into SVG stroke-width (user-space units). Default 1. Combined with scale, gives full control over emitted line weights.

Optional explicit width attribute on the root <svg> element. When omitted, set to the viewBox width (so the SVG renders at its native scale). Pass a unit string ("800", "100%", "210mm") to control downstream rendering.
