Drawing tools
Use drawing tools to create custom objects to appear at runtime.
Use the drawing tools to draw free-form and one-dimensional objects including:
- Rectangles and squares
- Ovals and circles
- Lines
- Polylines and polygons
By default, each drawing object has a MouseDown event and MouseUp event to which you can add methods.
To prevent a drawing from snapping to the grid as you draw, in 
Grid settings, clear Snap to grid.
