OnMLineStyleChangedEvent(MLineStyle, MLineStyle)

Declaration

protected virtual MLineStyle OnMLineStyleChangedEvent(MLineStyle oldMLineStyle, MLineStyle newMLineStyle)

TransformBy(Matrix3, Vector3)

Moves, scales, and/or rotates the current entity given a 3x3 transformation matrix and a translation vector.

Declaration

public override void TransformBy(Matrix3 transformation, Vector3 translation)

Parameters

Type	Name	Description
Matrix3	transformation	Transformation matrix.
Vector3	translation	Translation vector.

Overrides

EntityObject.TransformBy(Matrix3, Vector3)

Remarks

Non-uniform scaling is not supported for multilines. Explode the entity and, in case round end caps has been applied, convert the arcs into ellipse arcs and transform them instead.
Matrix3 adopts the convention of using column vectors to represent a transformation matrix.

Update()

Calculates the internal information of the multiline vertexes.

Declaration

public void Update()

Remarks

This function needs to be called manually when any modification is done that affects the final shape of the multiline.

If the vertex distance list needs to be edited to represent trimmed multilines this function needs to be called prior to any modification. It will calculate the minimum information needed to build a correct multiline.
