for calculation of the mass-inertial properties an array 'params' is filled;
for solids collision detection arrays 'params' and 'points' are filled;
for splitting into finite elements arrays 'points' and 'normals' are filled.
[in]dualSeams- Whether to keep seam edges polygons and their coincident points.
bool StepDataTune ( const MbCube cube,
