Element Description

m_cPoint

[MKI_3D_POINT] X-, Y- and Z-coordinates of the start point of the plane. The coordinates are in [mm] relative to the page center.

m_cVector1

[MKI_3D_VECTOR] X-, Y- and Z-components of the plane's first vector. The components are in [mm].

m_cVector2

[MKI_3D_VECTOR] X-, Y- and Z-components of the plane's second vector. The components are in [mm].

m_dValueA

m_dValueB

m_dValueC

m_dValueD

[double] Coefficients of the plane's equation. Will only be set correctly if point and vectors were set by means of a member function or its Init() was called.
