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).

Memory Usage

vRigger displays the amount of memory it is using on the right side of the status bar. The color of the text changes from green, to orange, to red as more memory is consumed.

Depending on your computer hardware, vRigger may feel sluggish when using a lot of memory. You can improve performance by reducing the number of large items on the workspace (especially inserted pictures), and by using the zoom commands rather than resizing individual items. You can also improve performance by temporarily disabling the Undo command on the General page of the vRigger Options dialog.
