This also applies to cable, chain, and webbing.

Gear that is anchored includes anchors, rocks, trees, tripods, trucks, etc.

A "bight" is a simple loop in a rope that does not cross itself.

A "bend" is a knot that joins two ropes together. Bends can only be attached to the end of a rope.

A "hitch" is a type of knot that must be tied around around another object.

"Descending devices" (e.g., ATCs, Brake Bar Racks, Figure 8s, Rescue 8s, etc) create friction as their primary purpose. The friction in descending devices is always considered when calculating forces.

The "Safety Factor" is the ratio between the gear's breaking strength and the maximum load applied to the gear (e.g., 5:1).

General Options

The General page in the vRigger Options dialog allows you to change various program preferences. To reset the options to their default values, click the Defaults button.


  • connecting gearAllow non-opening gear to connect. When checked, gear that doesn't open (e.g., the eye on an anchor) can connect to other gear that doesn't open. This option was used to connect the anchor and load shown to the right.
  • Always display "rotator on a stick". When checked, a "rotator" handle is displayed above the selected gear. When unchecked, the rotator handle is only displayed when multiple items are selected.
  • Automatically send error/usage information. Enabling this checkbox permits vRigger to send information to our computer programmers. This information helps us minimize bugs and improve vRigger. The information is not shared or used for marketing purposes. We encourage you to keep this feature enabled.
  • Display copyright notice on systems. When checked, a copyright notice will be displayed next to systems that are copied or printed. Learn more about copyrights and vRigger images.
  • Enable the rope arrangement commands. When this option is checked, five additional commands are available which provide additional control on the drawing order of individual rope segments.
  • Enable sounds. When checked, the gear will make sounds when it connects.
  • Reverse Shift key behavior during rotation. Pressing the Shift key when rotating gear normally constrains the rotation to 15° increments and releasing the Shift key allows unconstrained rotation. Choose this option to reverse this behavior.
  • Show Tip of the Day on startup. When checked, helpful program tips are displayed each time vRigger is started. You can also display the tips by clicking the Help button on the right side of the toolbar. The tips are automatically enabled when you install a new version of vRigger.

Undo options

  • Disable undo/redo. This disables the undo/redo commands and improves computer performance when many pieces of gear are displayed.
  • Enable undo/redo. This is the normal setting to support the undo/redo commands.
  • Temporarily disabled undo/redo. Selecting this option disables the undo command until a new file is opened.
