Pitney Bowes MapInfo Professional - Manual (Page 117)

The Move Duplicate Nodes in group of choices specifies whether MapInfo Professional will move
duplicate nodes when you use the Reshape command (on the Edit menu, click Reshape) to edit objects
that are adjacent to each other, such as regions.
• Choose None of the Layers to prohibit the product from moving duplicate nodes. This is the default
setting
• Choose Same Layer to move duplicate nodes that are in the same layer when one of the connected
nodes is moved.
The Digitizing Options group includes a Display Snap Radius check box to make the snap radius
larger or smaller. If you clear this check box, then the radius does not display when the snap mode is
turned on.
Type a new value in to the Snap Tolerance and Auto Node Tolerance boxes to specify the default
tolerance in pixels within which snap to node and Auto Node features operate. You use these settings
when you draw objects. (Click the S key to turn Snap to node on.) The default is five (5) pixels. Enter
a smaller value to obtain a tighter tolerance, and avoid snapping to the nodes of other objects as you
draw. Enter a larger value to obtain a looser tolerance, when you want to snap to a node even though
you are relatively far away from it.
For more information about the snap tolerance, see Using "Snap To" to Select Nodes and Centroids in
the Help System.
The Find Selection Options include:
• Zoom on Find Selection - Select this option to zoom to the selection each time you perform a Find
Selection for single and multiple objects. Clear this check box to prevent zooming when performing a
Find Selection.
• Find Selection after Paste - Select this option to turn on the Find Selection feature in the Map window
only after you Paste an object. If you have an active Browser, and the selection is in that Browser
window, the browser still scrolls to the selection. Clear this check box to prevent zooming after pasting
an object.
Projection tab (Map window dialog box)
The Projection tab on the Map Preferences dialog box has preferences for controlling the projection
of tables and a MapBasic session, and the format in which coordinates display.
Specify the default for:
• Table Projection - To set the default projections for the current map, designate a default table projection
for creating new tables, importing GML 2.1, MIF, MBI, and IMG files, and for Choose Projection
options in dialog boxes.
You can override the table projection defaults by clicking the Choose Projection button
throughout MapInfo Professional except when you use the Universal Translator, ArcLink, or
when you import DXF files. Note:
• Session Projection - To set the option to designate a default MapBasic projection for returning
coordinate values using a MapBasic window or Update Column. Compiled MapBasic applications
are not affected by this preference.
The Display Coordinates list has options for changing the format in which coordinates display. You
can select:
• Decimal Degrees - By default, MapInfo Professional displays coordinates in decimal degrees. MapInfo
Professional displays coordinates of objects in the Object Info dialog box, and of the cursor location
in the status bar if that display option is selected.
• Degrees, minutes, seconds - Choose this option to display your Map using the degree, minute,
seconds format.
