The drawing of the section being defined is in this part of the widow. The drawing changes in real time according to the different modifications made.
On the top right of the drawing there is a series of zooming tools to visualize the section in more detail. 
On the top toolbar, if we click the 
icon and graphically select one of the section’s vectors, the program displays information on its definition.
Additionally, you have two points of view, Front view and Top view.
