On drawing, only 2 dimension curve are used. If m_pCurve is a 3 dimension curve, m_pPlane must be defined. In this case, resulting curve of the projection on the given plane is used. In case of 2 dimension curve m_pPlane is not used.
m_sTrimInterval must be contained or equal to the curve interval definition.
Refers to Curves Module for more details.
Trim interval for the curve.
It must be contained or equal to the curve interval:
Projection plane in case of 3D curve.
