NODE (CTRL+N)

 

In eta/DYNAFORM nodes and points as "points" in a three dimensional space are different entities.  Points are used to form lines and surfaces while nodes are used to form elements.  There are two types of nodes, referenced nodes and un-referenced nodes (free nodes).  A referenced node is a node that is used by elements and is represented by a dot.  An un-referenced (free) node is a node that is not used by any element and is represented by an asterisk.  The functions in this menu are used to create nodes, change the position of the nodes, and delete free nodes.  The options are shown in Figure 5.4.1.
