This allows you to draw a rectangle by indicating its diagonally opposite vertices. Click on the “Rectangle” button in the tool bar.
You can also select the tool by going to the “Geometry” menu bar then to “Insert” and “Rectangle”.
To graphically draw a rectangle in the layer you are editing, select the tool and place the first vertex in the required position in the graphic area. The application will show a projection of the rectangle you are drawing. Move the mouse, choose the position for the vertex diagonally opposite the one you have already inserted and left click on the mouse to define it.
To work with the command console write the command “rectangle” and then input the coordinates for the first vertex and the diagonally opposite vertex.
