When you apply interactions, constraints, and connectors to regions of the model, you can choose to display symbols in the viewport that indicate where you have applied the interactions, constraints, and connectors. For information about graphical symbol types, see “Symbols used to represent interactions, constraints, and connectors,” Section C.2.
You can apply interactions, constraints, and connectors to native geometry or to an orphan mesh.
Interactions and constraints
If you apply an interaction or constraint to native geometry, symbols appear approximately equally spaced over the surface or surfaces to which the interaction or constraint is applied. If the interaction or constraint definition involves a node region rather than a surface, the symbols appear equally spaced on the edges of the node region and at any vertices in the node region. If the interaction or constraint is applied to a single vertex, a symbol appears at that vertex.
If you apply the interaction or constraint to an orphan mesh, symbols appear at the center of each element face for surface-based regions or at the nodes for node-based regions.
Connectors
When you apply a connector to wires, squares appear at the first points of the wires and triangles appear at the second points of the wires. If you specify an orientation other than the global coordinate system for orientation 1, an orientation triad appears at the first points of the wires. For orientation 2, an orientation triad appears at the second points of the wires only if you specify a coordinate system by name; if you toggle on the option to Use orientation 1, the orientation triad does not appear at the second points. The connection type label appears midway along a line between the endpoints of the selected wires.
For information about controlling the visibility of these symbols, see “Controlling the display of attributes,” Section 50.11.
