Description
|
|
•
|
The routine returns true if the given objects are perpendicular to each other; false if they are not; and FAIL if it is unable to reach a conclusion.
|
•
|
In case of FAIL, if the third optional argument is given, the condition that makes the given objects perpendicular to each other is assigned to this argument.
|
•
|
The command with(geom3d,ArePerpendicular) allows the use of the abbreviated form of this command.
