Class :blue:`MbMarker` is declared in file *marker.h*.

Auxiliary object marker :blue:`MbMarker` is defined by a point
**origin** and two orthogonal vectors **axisZ**,
**axisX**.

A marker is used to apply geometric constraints to objects of a
three-dimensional space. A marker is a representative of a geometric
object and can replace a three-dimensional point, a line, a plane, a
local coordinate system, and other objects when geometric constraints
are applied.
