This chapter describes how to manipulate the reconstruction pole hierarchy using the Modify Reconstruction Poles tool. For a description into Total Reconstruction Poles, see here in the Reconstructions chapter.

1 Modify Reconstruction Poles Tool

Found on the Tool Palette, the Modify Reconstruction Poles Tool is used to interactively modify the reconstruction poles for a given plate ID.

Icon	Tool	Shortcut	Operation
	Modify Reconstruction Pole	P	Drag or Shift+drag the current geometry to modify its reconstruction pole. Ctrl+drag to re-orient the globe by holding down Ctrl

1.1 Choosing a Plate ID to move

To select a Plate ID to move, the Plate needs to be in the field of view, and the reconstruction time needs to be at the correct geological time.

The second step is to select a feature which belongs to the plate ID that should be changed. Select the Choose Feature tool, , then click the mouse cursor on the feature. You can confirm that you have selected the correct plate ID by checking the Current Feature Panel.

Now select the Modify Reconstruction Poles tool, . Notice that all features belonging to the chosen plate ID are now highlighted.

1.2 Adjusting a Reconstruction Pole

After the feature plate has been selected with the Choose Feature tool it can be dragged anywhere on the globe. The plate can also be rotated by holding down Shift and dragging. The globe can still be re-orientated whilst dragging the plate by holding down Ctrl. The Task Panel will display information about the reconstruction pole.

Highlight Children.

Ticking this option will also highlight any plates that would be affected as a result of moving the selected plate due to the current rotation model.

1.3 Committing Changes to a Reconstruction Pole

1. Choose a pole sequence

2. Verify new relative pole

2 Move Pole

Icon	Tool	Shortcut	Operation
	Move Pole	O	Click on the pole marker and drag it to the desired location, or specify its location in the Move Pole Task Panel.

The Move Pole task panel allows users to manipulate the poles location by latitude and longitude. The panel also includes VGP and Stage Pole constraints.
