how to Creates a line of infinite length







Button

Summary
Lines that extend to infinity, such as xlines, can be used to create construction and reference lines, and for trimming boundaries. 


List of Prompts
The following prompts are displayed.
Specify a point or [Hor/Ver/Ang/Bisect/Offset.
Point
Specifies the location of the infinite line using two points through which it passes.
The xline is created through the specified point. 
 
Hor
Creates a horizontal xline passing through a specified point.
The xline is created parallel to the X axis. 
Ver
Creates a vertical xline passing through a specified point.
The xline is created parallel to the Y axis. 
 
Ang
Creates an xline at a specified angle. 
Angle of Xline
Specifies the angle at which to place the line.
Reference
Specifies the angle from a selected reference line. The angle is measured counterclockwise from the reference line.
Bisect
Creates an xline that passes through the selected angle vertex and bisects the angle between the first and second line.
The xline lies in the plane determined by the three points. 
Offset
Creates an xline parallel to another object.
Offset Distance
Specifies the distance the xline is offset from the selected object.
Through
Creates an xline offset from a line and passing through a specified point.
