Category in Advanced options dialog box: Analysis and design

If you set this advanced option to TRUE, the start number of a new analysis node is set according to the global z coordinate of the node. For example:

• If z is less than 1000.0, the node start number is 0.

• If z is between 1000.0 and 1999.0, the node start number is 1000.

• If z is between 2000.0 and 2999.0, the node start number is 2000.

The first free number above the start number is assigned to the node.

The default is FALSE.
