Point Definition

The different ways of defining a point, called point modes, are shown and selectable through a toolbar that pops up when applicable.

• ARC AT ANGLE

• ARC CENTRE

• AUTO POINT

• CENTRE OF GRAVITY

• NEAREST POINT ON SEGMENT

• CURSOR POSITION (FREE)

• DISTANCE ALONG

• EVENT POINT

• EXISTING POINT

• INTERSECTION

• KEY IN POINT

• MIDPOINT

• NODE/END POINT

• OFFSET FROM CURRENT

• SYMBOL CONNECTION

Whenever the user is requested to supply a point, the user can redefine the system-proposed point mode just by selecting the desired point mode from the toolbar. The system-proposed point mode may be "cursor position", the last used point mode or some other mode, depending mainly on the currently invoked function. The ADD OFFSET entry in the pop-up toolbar is used in combination with an arbitrary point mode, in order to add a keyed in offset to the point. When the system requests a point, the user may add an offset by clicking this field prior to the definition and keying in the offset when the definition is completed.
