Description: This command generates a straight line in the geometry perpendicular to the selected object that cross the introduced point.

Inline mode usage:

• perpendicular -h: Displays the help file that summarizes the parameters for this command.
• perpendicular –n <resulName> -s <selectionName> -p <pX> <pY> <pZ> <length>: Generate a straight line normal to the selectionName curve/surface and crossing the point <pX> <pY> <pZ> with the specific length.

Interactive mode usage:

• Invocation: perpendicular
• Parameters:
• Point in the perpendicular line.
• Length of the line.

Example:

The following example shows how to insert a perpendicular line to a surface generated by revolving a line.

command> line

First point [x y z]: 0.2 0 0

Second point [x y z]: 0.2 0 1

command> revolve

Select curves on screen (Press enter when done): 

Axis point 1 [x y z]: 0 0 0

Axis point 2 [x y z]: 0 0 1

Initial Angle [degrees] {default 0.0}: 

Final Angle [degrees] {default 360.0}: 90

command> perpendicular

Insert the coordinates of a point in the perpendicular line [x y z]: 0.5 0.5 0.0

Insert the length of the perpendicular line: 0.75

command> 

Result:

Resulting perpendicular line
