Axial attributes of both 3D and 2D primitives define a position and a direction. An axial attribute of a 3D primitive may be specified as a direction in one, two or three dimensions or as a P-point. Similarly, the axial attribute of a 2D primitive may be specified as a direction in one or two dimensions or as a P-line.

If an axial attribute of a 3D primitive is specified as a P-point, the direction of the axis is taken to be the direction of the P-point, and the origin of the axis to be the position of the P-point. If the axial attribute is specified as a direction, the origin of the axis is taken to be the component origin, i.e. the position of P-point 0.

Examples

PAAX -P2	sets PAAX to be opposite the direction of P-point 2 with its origin at the position of the P-point
PBAX X34-Y	sets PBAX to the given direction from the component origin
PCAX X45Y30Z	sets PCAX to the given direction from the component origin
PAXI X DDANG Z	takes the Design DDANGLE and calculates the direction accordingly

Syntax

   |-- Y --|

   ‘-- Z --+-->

If the axial attribute of a 2D primitive is specified as a P-line, the direction of the axis is taken to be the direction of the P-line, and the origin of the axis to be the position of the P-line. If the axial attribute is specified as a direction or direction expression, the origin of the axis is taken to be the component origin.

Examples

PLAX PLIN NAXI	sets PLAX to be the direction of the P-line whose PKEY attribute is NAXI; the origin of the axis is at the position of the P-line
PLAX X60-Y	sets PLAX to the given direction from the component origin

Syntax

where <axis> is

>--+-- X --.

‘-- Y --+-->

and <plkey> is the PKEY attribute of the P-line.
