X-Pt, Z Axis

Synopsis

obj = CSYS/point,line[,ORIGIN,{point|x,y,z}]

Description

Establishes a coordinate system such that the default origin is at the intersection of the existing line and an imaginary line, normal to the existing line, through the existing point. The Z axis is coincident with the existing line, and the X axis is coincident with the imaginary line.

The negative and positive directions of the Z axis depend on the existing line's start and end points, respectively. The positive direction of the X axis is toward the existing point. The positive and negative directions of the Y axis follow the right hand rule.

Parameters

Parameter

Description

point

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

line

An existing line which establishes the orientation of the coordinate system. The direction of the positive Z axis points toward the second end point of the line.

ORIGIN

Minor word which indicates that the point in the next field is 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.
