Model Reference Manual

Examples:
ROTATE BY -45	Rotates by 45° about the element’s Neutral Axis or Z axis (anticlockwise when looking from Start to End or in the +Z direction, since the rotation is specified as a negative angle).
ROTATE BY 45 ABOUT E	Rotates by 45° about the E-W axis (clockwise when looking E).
ROTATE ABOUT E BY 45	The same as the preceding example.
ROT THRO POSE ABOUT S BY -25	Rotates a Section about an axis which passes in the N-S direction through its End position. The rotation is 25° anticlockwise when looking S along this axis.
ROT ABOUT PPLIN TOS BY 45	Rotates by 45° about the Top-of-Steel p-line (clockwise when looking in the Start to End direction).
ROT AND PPLIN BOS IS E45N	Rotates element about its Neutral Axis until the Bottom-of-Steel p-line points as closely as possible to the E45N direction.
ROTATE AND Y IS N45W25D	Rotates element until the Y axis points as closely as possible to the YN45W25D direction.
ROT AND PPLIN TOS IS PPLIN BOS OF /SCTN1 LEAV DIR WRT /STRU1	Rotates element until its TOS p-line points in the direction of the BOS p-line of / SCTN1 in the specified coordinate system.
