Design Element Orientation

Keywords:

ORIENTATE

Description:

Every Design element has its own co ordinate system which consists of a right-handed set of East (X), North (Y) and Up (Z) axes. The precise orientation of an element must be given as two statements fixing the direction of two axes, for example, ORI Y IS NORTH AND Z IS UP. When rotating symmetrical items, such as cylinders, it may be sufficient to give one axis direction only (allowing Design to choose the other), for example, ORI P1 IS N45E. Regardless of the command given, orientation always occurs about the Current Element origin.

Command Syntax:
