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 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).


You can display a grid similar to graph paper on the vRigger workspace.

Do one of the following to display the grid:

  • Select Gridlines in the Show/Hide group on the View toolbar
  • PressCtrl+G

When enabled, the grid will also be displayed when the system is printed or copied to the clipboard.


Do one of the following to control whether gear should "snap" to the nearest gridline:

  • Select Snap to Grid in the Show/Hide group on the View toolbar
  • Press Ctrl+K

The Snap command is only available when the grid is displayed.

You can still nudge gear using the arrow keys regardless of whether snapping is enabled.
