Add and Select a Point Entity
- 
                Activate a point collector on any panel.
                 
 Figure 1. Activated point collector on a joint panel
- 
                Hover the mouse over an edge or a surface of a graphic entity mentioned above
                    (Cylinder, Box, or CADGraphic). The location where the point can be created is
                    indicated with a cross. 
                - A red cross indicates the current location where the point would be created if clicked.
- A yellow cross indicates other potential locations for the point.
- To pick any of the locations at the red cross, move the mouse towards that location. When the mouse cursor is closer to the location, the yellow cross turns red.
- When the cursor is on an edge away from any of its vertices, the center of the edge is the only location available for creating/selecting the point.
 Points can be added using following graphics entities:- Straight edge (edge center or at either ends)
-

- 
                Click to create/add a point at that location. 
                The point is automatically selected in the collector.Note: A label and varname is automatically assigned to the newly created point. This newly created point is simultaneously used in the panel of the parent entity being created.
