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. "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). This page contains tips to help you customize the routing of ropes in vRigger. Sometimes a rope will enter a piece of gear "backwards" or the strands of rope will cross. This is more common with a friction device, like a Petzl I'D. You can often solve this by moving the items that are adjacent to the gear (e.g., moving the tail of the rope up/down or left/right) or you can reverse the routing of the rope. You can move a segment of rope behind, or in front of, other gear using the Draw in Front of All Gear or Draw Behind All Gear arrange rope segments commands. You can use "slack points" to route the rope to any location on the workspace. Slack points are extremely powerful and often overlooked. Learn about slack points.
