Warpage Visualization Tools dialog-Best Fit tab

Best fit minimizes the deflection for the nodes specified. The default is all nodes. Visually, it makes the part shrink to the center of the part when all nodes are selected. Best fit can be used with a subset of nodes. To select nodes, a layer with nodes must be displayed before the nodes can be selected.
Note: To select more than one node, hold the Ctrl key while doing your selection, or use band selecting.

Node IDs Enter the IDs of nodes, or select them directly on the model.
All nodes When checked, best fit uses all nodes in the model.
Apply on [drop-down] Select whether you want the settings above to be applied to the current deflection plot only, all deflection plots for the current study, or all deflection plots for all currently open studies.
