— Divide this trapezoid shape belonging to volume "voldiv" into ndiv volumes called divname, from start position with the given step.

Only Z divisions are supported. For Z divisions just return the pointer to the volume to be divided. In case a wrong division axis is supplied, returns pointer to volume that was divided.
