Points and Directions
When a dialog box requires inserting a point it is possible to answer with one of the following actions:
•??? enter the digital values of the coordinates via keyboard, separating them with a comma. The various coordinates can be expressed as digits (for instance 10) or as digital expressions to evaluate (for instance 5+5);
•??? recall the values by using the calculator available next to the editable field;
•??? move the mouse cursor towards the graphics area in order to acquire a notable point (final, medium, near, centre, intersection) or a direction of one of the already drawn entities or a generic point (sketch) of the graphics area.
The direction is measured from the semi-axis of the positive X counterclockwise.
Also with directions or any other digital value it is possible to enter a digit or a digital expression to evaluate.
