Component Orientation

Model Reference Manual

This command rotates the Component about its origin so that (in forwards mode) the Arrive p-point is in the opposite direction to the previous Component’s Leave p-point.

If the Component is not concentric, it is necessary to specify the off-line orientation as well. This is usually done by giving the direction of an off-line p-point. If it is not possible to achieve an orientation because of the direction of the constrained centreline, MODEL will leave this off-line direction in the closest orientation to that requested.


Examples:
ORI	Rotate the current element about its origin so that (in forwards mode) its Arrive Point is in the opposite direction to the previous Component’s Leave Point (see Figure 8:6.: Orienting a Concentric Component).
ORI AND P3 IS U	As above, and orient the off-line p-point (P3) in the specified direction (see Figure 8:7.: Orienting a non-concentric Component by means of an off-line p-point).

Note:

The ORIENTATE command will not change the ANGLE, RADIUS etc. of a variable Component to accommodate an oblique off-line direction.
