The Point Pattern function is used to group a set of points or arcs so that they can be selected as a single entity (point pattern), usually for machining purposes. You can select any combination of points and/or arcs. When you select points, the software creates an arc at that point, using the Hole Radius value, for each point. When you select arcs, they are changed to the Hole Radius value and the center point is added. After creating the pattern, it can be selected as a single entity.
Hole Radius - sets the radius of the arcs created from the selected points. If arcs are selected, they are changed to this value.
