Synopsis
PDX_MSGT step_SetPlaneAngleUnit(long angle_unit)
Purpose
Specifies current STEP plane angle units (degrees or radians)
Description
Specifies current STEP plane angle units (degrees or radians). All conversions involving angular values must take the current setting into consideration. This function must be called prior to any conversions (i.e., sgdx* or smap* functions) between GDX and STEP geometry entities. The STEP plane angle units are defaulted to degrees by step_Initialize.
Input
angle_unit
STEP_DEGREES
Current plane angle unit is degrees
STEP_RADIANS
Current plane angle unit is radians
STEP_RADIANS_LITERAL
Parameterization is degrees other values radians
Return
STEP_NOERR
STEP_ILLEGAL_PLANE_ANGLE_UNIT
