Identification: 3DNR [-] (only in 3D model files, *.3d)

The nodes and elements in deeper layers of 3D models are automatically numbered by adding a multiple offset value to the number in the topmost layer. The default offset is 10,000 and can be changed with the help of 3DNR. However, the highest node number of the top node layer should be less than the selected offset. The offset numbering will change automatically when the mesh generator of SPRING creates a node number in the top layer, which is greater than the offset numbering.

Example: 3DNR = 15000

The node 15 in the topmost layer corresponds to node 15015 in the second and 30015 in the third node layer.
