Points

A free point is a zero-dimensional geometry entity in space that is not associated with a surface. It is displayed as a small "x", and its color is determined by the component collector to which it belongs. These types of points are typically used for weld locations and connectors.

A fixed point is a zero-dimensional geometry entity that is associated with a surface. It is displayed as a small "o", and its color is determined by the surface to which it is associated. The automesher places a node at each fixed point on the surface being meshed. A fixed point that is placed at the junction of three or more non-suppressed edges is called a vertex or vertex point. Such vertices cannot be suppressed (removed).
