Users with HUGE drawings may want to consider changing the value of the TREEDEPTH variable. It controls the GstarCAD Tree Spatial Index, which specifies the number of times the tree-structured spatial index may divide into branches. Setting the value to -3020 flattens the Z index giving you more granular nodes in the XY which yields faster object selection. It has no effect on the elevations of your objects.
