3D_Y_SCALE

3D_Y_SCALE N,CY

SHRINKS OR STRETCHES THE 3D OBJECT NUMBER N OF CY ALONG ITS Y AXIS

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

ACTION

The command 3D_Y_SCALE scales the 3D object designated by its number N, along its own Y axis, by the coefficient CY.

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

If CY=1, no scale is made.

If CY>1, the 3D object is streched on its Y axis.

If CY<1, the 3D object is shrinked on its Y axis.

SYNTAX: 3D_Y_SCALE N,CY

  • 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.
  • CY = coefficient. Must be greater than 0.

USE

  • The command 3D_Y_SCALE is used to dimension a 3D object on its own Y 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 CY is not a correct expression.
  • If the coefficient CY is less than or equal to 0.
