Cone

The Cone option allows you to add cone traces or "small circles" on the stereonet. The cones can be centered about any axis, and may represent friction circles, toppling bounds, etc.

There are three ways to add cones:

• Cone (Fixed Angle) : The cone angle is fixed while the cone center is defined graphically
• Cone (Fixed Center) : The cone center is fixed while the cone angle is defined graphically
• Cone (Fixed Center and Angle) : The cone center and angle are fully defined

To add a cone with fixed angle:

1. Select Stereonet > Cone (Fixed Angle) from the Tools ribbon.
2. In the Edit Cone dialog, enter the Cone Angle.
3. Click OK. A cone with the specified Cone Angle appears, and the Cone Orientation (i.e., center) follows the mouse.
4. Left-click to place the cone.
5. The Edit Cone dialog appears with options to modify the Color, Orientation, and Cone Angle. The Orientation and Cone Angle can be graphically modified by left-clicking and dragging the handles.
   
6. Click OK to finalize the Cone and add it to the view.

To add a cone with fixed center:

1. Select Stereonet > Cone (Fixed Center) from the Tools ribbon.
2. In the Edit Cone dialog, enter the Orientation.
3. On OK, a cone with the specified Orientation appears, and the Cone Angle is resized with the mouse.
4. Left-click to place the cone.
5. The Edit Cone dialog appears with options to modify the Color, Orientation, and Cone Angle. The Orientation and Cone Angle can be graphically modified by left-clicking and dragging the handles.
   
6. Click OK to finalize the Cone and add it to the view.

To add a cone with fixed center and angle:

1. Select Stereonet > Cone (Fixed Center and Angle) from the Tools ribbon.
2. In the Edit Cone dialog, enter the Orientation and Cone Angle.
3. Click OK to finalize the Cone and add it to the view.

Small circles can be confusing on a two-dimensional projection, so be sure you understand their geometry before using them for interpretation.

Editing Cones

After a Cone has been added, it can be moved, formatted, etc.

To edit a cone:

1. Select a cone from the Visibility tree or graphically by left-click.
2. Select Edit Tool from Properties pane or Annotation > Edit Tool from the Tools ribbon.
3. In the Edit Cone dialog, enter the Orientation and Cone Angle or graphically change the cone orientation by dragging the center point, or change the cone angle by dragging the perimeter of the cone.
4. Click OK to finalize editing.

See the Edit Tools topic for details.
