Origin, X-Pt, Y-Pt

Synopsis

obj = CSYS/point1,point2,point3[,ORIGIN,{point|x,y,z}]

Description

Establishes a coordinate system such that the default origin is at point1. The X axis is coincident with an imaginary line between point1 and point2, and the Y axis lies in a plane created by the three points.

The positive direction of the X axis is toward point2, and the positive direction of the Y axis is toward point3. The positive and negative directions of the Z axis follow the right hand rule.

Parameters

Parameter

Description

point1

An existing point which is used to establish the orientation of the coordinate system. If the ORIGIN parameter is not specified, this point serves as the coordinate system origin.

point2

An existing point which is used to establish the orientation of the coordinate system and the direction of the positive X axis.

point3

An existing point which is used to establish the orientation of the coordinate system and the direction of the positive Y axis.

ORIGIN

Minor word which indicates that the point in the next field is to be the coordinate system origin.

point

An existing point which establishes the coordinate system origin.

x,y,z

The x, y, and z coordinates where you want to place the coordinate system origin.

Parameter	Description
point1	An existing point which is used to establish the orientation of the coordinate system. If the ORIGIN parameter is not specified, this point serves as the coordinate system origin.
point2	An existing point which is used to establish the orientation of the coordinate system and the direction of the positive X axis.
point3	An existing point which is used to establish the orientation of the coordinate system and the direction of the positive Y axis.
ORIGIN	Minor word which indicates that the point in the next field is to be the coordinate system origin.
point	An existing point which establishes the coordinate system origin.
x,y,z	The x, y, and z coordinates where you want to place the coordinate system origin.
