NODESEL,<N1>, … <N20>
Selects up to 20 nodes that will be highlighted on a 3d plot. This command highlights the nodes in the model on all current and future plots. Each plot type has its own different display rules on how these nodes are highlighted. If more than 20 nodes are to be selected, multiple instances of this command can be used, as nodes are not deselected between commands. The nodes can be deselected by using NODESEL command again on a selected node with the node number to be deselected.
