UserCoordinateSystemDefinition.SetByThreePoints Method

Parent Object: UserCoordinateSystemDefinition

Description

Method that sets the inputs that fully define the coordinate system. This method returns a failure in assembly documents.

Syntax

UserCoordinateSystemDefinition.SetByThreePoints( Origin As Object, XDirectionPoint As Object, YDirectionPoint As Object )

Parameters

Name Type Description
Origin Object Input object that specifies the origin of the coordinate system. This can be one of the following objects: WorkPoint, Vertex, SketchPoint, SketchPoint3D or Edge. If a linear Edge is specified, it's midpoint is used. If circular or elliptical edges are specified, their center is used.
XDirectionPoint Object Input object that specifies a point defining the x-direction for the coordinate system. The vector from the origin to this point defines the x-direction vector. This can be one of the following objects: WorkPoint, Vertex, SketchPoint, SketchPoint3D or Edge. If a linear Edge is specified, it's midpoint is used. If circular or elliptical edges are specified, their center is used.
YDirectionPoint Object Input object that specifies a point defining the y-direction for the coordinate system. This can be one of the following objects: WorkPoint, Vertex, SketchPoint, SketchPoint3D or Edge. If a linear Edge is specified, it's midpoint is used. If circular or elliptical edges are specified, their center is used.

Samples

Name Description
UCS by three points This sample demonstrates the creation of a User Coordinate System (UCS) based on 3 points that define the origin, x-direction and y-direction for the UCS.
