Mini-CAD: Activating the Mini-CAD functions
Information on each function can be seen if the mouse pointer is placed over a Mini-CAD toolbar icon without pressing the mouse button.
In order to activate the respective function you must first select the object to be drawn (line, circle, rectangle, text, graphics, etc.) with a mouse click on the corresponding icon. Activated icons are displayed inverted.
To draw the required object, click with the left mouse button on the point in your system where the object is to be drawn. The object can be precisely positioned later using the drawn object's editor.
The "CAD without Shift" 
If the icon is not activated the drawing process can be initiated by concurrently pressing the [Shift] key and the left mouse button. The [Shift] key can then be released.
