Creates a polygon with a right angle between the first and the last line segment.
To generate automatically right angles (or 45 degree):
•Turn off snap mode
•Press and hold down the Ctrl key while digitizing (from the second node)
If the conditions Snap mode=off and Ctrl keys=hold are not met, a warning box appears. You can suppress the warning until the next MapCAD start.
Complete digitization with a double-click to the last corner point (NOT back to the starting point). The last line segment is automatically generated with a right angle to the first line segment (by moving the first digitized node).
