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).

Working with Slack Points

Special items, named "slack points," allow you to position a rope anywhere on the workspace. They are a powerful, and often overlooked, tool in vRigger.

You add a slack point by dragging one from the Gear Finder or a gear pane and dropping it on chain, rope, or webbing. Unlike other items in vRigger, you can drop a slack point on a rope.

You can drag the slack point anywhere on the workspace to route the rope to that location. Slack points are only visible when something is selected on the workspace.

Creating an edge using a slack point

You can use a slack point to show that a rope is passing over an edge as displayed in the following illustration. You can even modify the friction of a slack point so the edge will be considered during force calculations.

In the above illustration we used a line "shape" to draw the edge.

Creating rope connections using slack points

You can use slack points to "create" additional rope connection points on gear. For example, four slack points were used in the following illustration to create the appearance that the rope is connected to, and deflected by, the chairlift.

A sample file explains how the rope was routed around the chair.

Slack points were used in this next illustration to connect the ropes to a value. We've shown the slack points in this illustration, but they will be hidden unless something is selected on the workspace.

Connecting ropes

The page that explains how to insert a picture shows how you can use slack points to "connect" gear to a mountain and an industrial site.

Using Slack Points with Webbing

When a slack point is connected to webbing, you can rotate the slack point to create, or remove, twists in the webbing.

You can use multiple slack points to simulate curves in chain and webbing.
