3D_Z_SCALE

3D_Z_SCALE N,CZ

SHRINKS OR STRETCHES THE 3D OBJECT NUMBER N OF CZ ALONG ITS Z AXIS

  • Type: Command
  • Parameters: 2
  • Group: 3D Objects

ACTION

The command 3D_Z_SCALE scales the 3D object designated by its number N, along its own Z axis, by the coefficient CZ.

The own Z axis of the 3D object is the axis of the object which was parallel to the world Z axis when the 3D object was created.

If CZ=1, no scale is made.

If CZ>1, the 3D object is stretched on its Z axis.

If CZ<1, the 3D object is shrinked on its Z axis.

SYNTAX: 3D_Z_SCALE N,CZ

  • N = 3D object number (integer or real). Must be greater than 0 and less than or equal to the allowed maximum number of 3D objects.
  • CZ = coefficient. Must be greater than 0.

USE

  • The command 3D_Z_SCALE is used to dimension a 3D object on its own Z axis.

ERROR

  • If number N is not a correct expression.
  • If number N exceeds the allowed maximum number of 3D objects.
  • If number N is not greater than 0.
  • If 3D object number N does not exist.
  • If the coefficient CZ is not a correct expression.
  • If the coefficient CZ is less than or equal to 0.
