Constructors

constructor

new AcGeShape2d(): AcGeShape2d
Returns AcGeShape2d
Inherited from AcGeShape.constructor

Properties

`Protected`_boundingBoxNeedsUpdate

_boundingBoxNeedsUpdate: boolean = false

Accessors

boundingBoxNeedUpdate

get boundingBoxNeedUpdate(): boolean
When this is set, it calculates the bounding box of this shape and resets this property to false. Default is false.

Returns boolean
Inherited from AcGeShape.boundingBoxNeedUpdate
- Defined in geometry/AcGeShape.ts:11

box

get box(): AcGeBox2d
The bounding box of this shape. Because it is a time-consuming operation to calculate the bounding box of one shape, the bounding box value is cached. It will be calculated again lazily once there are any changes to properties of this shape.

Returns AcGeBox2d
- Defined in geometry/AcGeShape2d.ts:31

Methods

`Protected` `Abstract`calculateBoundingBox

calculateBoundingBox(): AcGeBox2d
Return true if this shape contains the specified shape

Returns AcGeBox2d
- Defined in geometry/AcGeShape2d.ts:42

`Abstract`transform

transform(matrix: AcGeMatrix2d): this
Transforms the entity by applying the input matrix.
Parameters
- matrix: AcGeMatrix2d
  Input transformation matrix
Returns this
- Defined in geometry/AcGeShape2d.ts:24

translate

translate(v: AcGeVector2dLike): this
Return new shape translated by given vector.
Parameters
- v: AcGeVector2dLike
Returns this
- Defined in geometry/AcGeShape2d.ts:16
