Reshaping Map Objects - MapInfo_Pro - 2023

You can reshape regions, polylines, lines, arcs and points. A region is an object created with the Polygon command. You cannot reshape objects created with the Rectangle, Rounded Rectangle, and Ellipse command.

To reshape an object:

1. Select an object with the Select command.
2. On the SPATIAL tab, in the Edit group, click Reshape from the list.

   You are now in Reshape mode. MapInfo Pro draws nodes at every juncture where two polyline or polygon line segments meet.

3. To reshape the object, move the nodes, add nodes, or delete nodes from the object.

   To move a node, click it and, while holding down the mouse button, drag the node to the desired location. The line segments connected to the node are moved to a new position.

   To add a node, on the SPATIAL tab, in the Edit group, click Add Node from the list. Position the cursor where you want to add the node, and click the mouse button. MapInfo Pro adds a node. You can move this node or delete it, just as you would any node.

   To delete a node, position the cursor over the node, click it, and press the Delete key. To delete the last node when creating a polyline or polygon, click the Backspace key.

The Reshape command is very useful when you are creating sales territories or other merged boundaries. For example, you are merging postal code boundaries together to create school districts. Some postal code boundaries fall into more than one school district. Use the Reshape command to reshape the school district to incorporate a section of a postal code boundary.

Reshape mode remains turned on until you turn if off. To turn off reshape mode, on the SPATIAL tab, in the Edit group, click Reshape.

Moving the Endpoints of an Arc

You can also change the endpoints of an arc with the Reshape command. Select the arc with the Select command and then choose Reshape. Grab either end of the arc and move it to the desired location. Reshaping an arc will not change the shape of the ellipse that it is part of, merely its endpoints.

Selecting Multiple Nodes

Reshape mode allows you to easily select nodes of an existing object and copy and paste them, drag them to reshape the object, or delete them. To trace an existing object, we recommend that you use the autotrace feature, which is explained in the next section, Snap to Nodes. The following illustrations show how to copy the border between Kentucky and Indiana.

1 Select the object. Click Reshape mode to display the nodes.

2 Select the nodes you want to copy.

3 Choose Copy and Paste to display the new objects with edit handles (small squares).

4 Click and drag the object to move to another location.

To reshape an object (such as the state of Kentucky):

1. Select Kentucky to enable Reshape mode.
2. Select the first node with the Select command. On the SPATIAL tab, in the Selection group, click Select, and Select. Click on the object in the map.

   Shift-click the last node to be copied. MapInfo Pro selects all nodes between following the shortest route. (To select all nodes except those between the shortest distance, use Ctrl-click with the Select command.)

3. On the HOME tab, in the Clipboard group, click Copy to copy the nodes to the clipboard.
4. Paste the duplicate nodes onto the map. On the HOME tab, in the Clipboard group, click Paste.

   The object you copied is drawn on top of the original object as a polyline.

5. To move the polyline click it and drag the polyline to a new location.
