1. | The translated coordinates are the matrix multiplied by the initial coordinate plus the global translation given by Tx, Ty and Tz. |
The matrix is orthonormal and with this option it allows coordinate rotation, translation and symmetry, but does not allow scaling or shear.
2. | A transformation can not apply to a node group and a submodel at the same time. |
3. | If the transformation is done on a submodel, all the options of this submodel are transformed. |
4. | A node can not be transformed both in a submodel and a node group. |
