Accessors

entity

get entity(): AcDbEntity | null
Assign the preview entity used by the jig.

The entity should be transient (not yet added to the model database).

Returns AcDbEntity | null
Inherited from AcEdPreviewJig.entity

`Protected`previewEntities

get previewEntities(): AcDbEntity[]
Flat list of transient preview entities derived from previewEntries.

Returns AcDbEntity[]
- Defined in packages/cad-simple-viewer/src/editor/input/AcEdSelectionPreviewJig.ts:129

Methods

`Protected` `Abstract`buildTransforms

buildTransforms(value: T): AcEdSelectionPreviewTransform[]
Builds world-space transforms for every transient preview entity.
Parameters
- value: T
  Current prompt input sampled by the editor.
Returns AcEdSelectionPreviewTransform[]
- Defined in packages/cad-simple-viewer/src/editor/input/AcEdSelectionPreviewJig.ts:138

end

end(): void
Disposes batch overlays and removes transient preview entities.

Returns void
Overrides AcEdPreviewJig.end
- Defined in packages/cad-simple-viewer/src/editor/input/AcEdSelectionPreviewJig.ts:180

render

render(): void
Publishes transient clones once and applies the latest cached transforms.

Returns void
Overrides AcEdPreviewJig.render
- Defined in packages/cad-simple-viewer/src/editor/input/AcEdSelectionPreviewJig.ts:163

update

update(value: T): void
Applies the latest transform to batch overlays or caches transforms for the transient clone path.

Subclasses with copyCount > 1 batch previews should override this method and call AcEdBatchedPreview.updatePlacements when appropriate.
Parameters
- value: T
  Current prompt input sampled by the editor.
Returns void
Overrides AcEdPreviewJig.update
- Defined in packages/cad-simple-viewer/src/editor/input/AcEdSelectionPreviewJig.ts:149
