Detailed Description

This class is used to compute the orientation of 2D elements and to build the corresponding markers.

Angles alpha and beta are used to determine the local coordinate system for the 2D element. If vect is not None, it is used instead of alpha and beta.

_buildDefaultMarker()

def _buildDefaultMarker (   self,   center,   normal,   warnings = True  )

private

Create the default marker, that use the normal vector of the 2D object as the local Z axis and the global X axis to determine the local X axis.

warnings can be used to enable or disable the logging of warning messages.

_buildMarkerRefVecX()

def _buildMarkerRefVecX (   self,   center,   normal,   refVecX  )

private

Create a marker using normal as Z axis and refVecX to determine the X axis.

buildMarker()

def buildMarker	(		self,
			geom,
			center,
			normal,
			warnings = True
	)

Create a marker with origin center and normal as Z axis.

The other axes are computed using the parameters alpha and beta of the Orientation2D instance. geom is the pseudo-geompy object used to build the geometric shapes. warnings can be used to enable or disable the logging of warning messages.
