Constructors

constructor

new AcGeArea2d(): AcGeArea2d
Create one 2d area defined by one outter loop and multiple inner loops

Returns AcGeArea2d
Overrides AcGeShape2d.constructor
- Defined in geometry/AcGeArea2d.ts:23

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 AcGeShape2d.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
Inherited from AcGeShape2d.box
- Defined in geometry/AcGeShape2d.ts:31

loops

get loops(): readonly AcGeLoop2dType[]
The loops of this area

Returns readonly AcGeLoop2dType[]
- Defined in geometry/AcGeArea2d.ts:41

outter

get outter(): undefined | AcGeLoop2dType
Outter loop of this area

Returns undefined | AcGeLoop2dType
- Defined in geometry/AcGeArea2d.ts:48

Methods

add

add(loop: AcGeLoop2dType): void
Append one loop to loops of this area. If it is the first loop added, it is the outter loop. Otherwise, it is an inner loop.
Parameters
- loop: AcGeLoop2dType
  Input the loop to append
Returns void
- Defined in geometry/AcGeArea2d.ts:33

buildHierarchy

buildHierarchy(): AcGeIndexNode
Returns AcGeIndexNode
- Defined in geometry/AcGeArea2d.ts:91

calculateBoundingBox

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

Returns AcGeBox2d
Overrides AcGeShape2d.calculateBoundingBox
- Defined in geometry/AcGeArea2d.ts:58

getPoints

getPoints(numPoints: number): AcGePoint2d[][]
Return boundary points of this area
Parameters
- numPoints: number
  Input the nubmer of points returned for arc segmentation
Returns AcGePoint2d[][]
Return points
- Defined in geometry/AcGeArea2d.ts:81

transform

transform(_matrix: AcGeMatrix2d): AcGeArea2d
Transforms the entity by applying the input matrix.
Parameters
- _matrix: AcGeMatrix2d
  Input transformation matrix
Returns AcGeArea2d
Overrides AcGeShape2d.transform
- Defined in geometry/AcGeArea2d.ts:70

translate

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