Add Points
Generating new points and later connecting them to form facets can extend individual object constructions. Completely new constructions are also possible. You could, for example, draw a simple triangle in the extrude-editor and create an extruded flat triangle object. Then add new points to the object relating to your construction requirements and connect them to form new surface facets.  
To generate new points for an object you must first change to the corresponding work mode by selecting the <Add Pnts> tab in the tool window. Then mark the object you want to edit and activate point selection by pressing the button.  
In the viewport window large crosshairs appear. Click within the 4 arrow buttons at the center of the crosshairs to grab it, then hold the left mouse button pressed and drag the crosshairs into the position where you want to generate the new point. Make use of the "Mouse Lock" and the "Snap" functions to support precise positioning. The x-, y- and z-coordinates of the new point can, however, also be input directly through the keyboard. To create the new point, just operate the <Add Point> button.  
Individual, unconnected points that are not components of a surface are only visibly and highlighted if the Point- entry under "View" in the menu bar has previously been switched on. Check on this if the newly generated points are not seen on the screen.  
 
Connect Points
After you have produced new points, you will want to connect them to form new triangular facets. Simply mark three points and then operate the <Add Facet> button to create a new triangular facet from them.  
 
In the foregoing example you see a basic square object. A point has been generated in each of the 4 corners of the window with the "Add Point" function.  
 
Four new facets are generated with the help of the "Add Facet" function. In each instance one corner point of the inside quadrilateral has been connected with two of the newly created outer corner points.
