$NP_TYPE

Function
Enter the protection area element type in the system variable.
Type: "FRAME"
A protection area element of the "FRAME" type does not contain any bodies, but defines a
coordinate transformation of the local coordinate system. The coordinate transformation
affects all the following ($NP_NEXT (Page 234)) and/or parallel ($NP_NEXTP (Page 235))
protection area elements. The values of the coordinate transformation are set via:
● Offset: $NP_OFF (Page 246)
● Direction vector of the rotation: $NP_DIR (Page 247)
● Angle of rotation: $NP_ANG (Page 249)
No parameters are specified in $NP_PARA (Page 245) for the "FRAME" type.
Type: "BOX"
A protection area element of the "BOX" type defines a paraxial box in the local coordinate
system of the protection area element. The mid-point of the box is at the origin of the local
