Bounds
•From editable layer: The computational accuracy is defined by the coordinate system bounds of the editable layer. If no layer is editable, the coordinate system of the map window is used.
•From current map window: The computational accuracy is defined by the boundaries of the current map section. All objects that are to be modified or created must be completely visible in the map window.
If Latitude/Longitude projection is enabled or only raster layers are opened, then the boundary settings are disabled.
Tolerance Radius
To be able to exactly snap to an object, you can choose between three cursor sizes: small / medium / large
Add node
Can be used as the default setting for some MapCAD functions. If the option is checked, the Perpendicular and Right Angle functions convert rectangles into region objects. Optionally, you can define if additional nodes will be inserted in the reference layer where objects are snapped to (Snap to Lines).
Snap to Lines
Define the desired reference layer. All layers that are set to selectable will be provided. Enabling the Add Node option inserts nodes in the reference layer at the intersection. See also: Snap to Lines
Mathematical Coordinate System (360 degrees)
Orientation East, counter clockwise. This is the default setting.
Metes and Bounds – USA LSS (N/S xxx° yy’ zz’’ E/W)
Enabling this option, the functions Create Line/Polyline, Polar Append, Calculate Direction and Move will be executed by using compass-like settings.
Orientation North-East (N xxx° yy’ zz’’ E) clockwise
Orientation North-West (N xxx° yy’ zz’’ W) counter clockwise
Orientation South-West (S xxx° yy’ zz’’ W) clockwise
Orientation South-East (S xxx° yy’ zz’’ E) counter clockwise
