The style of the current selection can be changed with the dialogs Selected Nodes and Selected Edges.

Nodes

Curve

Size of the curve control handles, it controls the way a ropes approaches the cusp point.

Angle

Minimum angle between edges for which a cusp shall be drawn.

Distance

Distance of the cusp point from the node position.

Cusp Style

The four built-in cusp types

There are four built-in cusp types:

Pointed
The cusp is formed by two arches meeting at an angle.
Round
The cusp is curved and there are no sharp corner.
Polygonal
The entire cusp is made of straight lines.
Ogee
The cusp is formed by two specular sigmoid curves.

Other shapes can be obtained from the plugins

Edges

Curve

Size of the curve control handles, it controls the way a ropes approaches the center of an edge.

Gap

Distance between the ends of a loop then a rope passes under another rope.

Slide

Offset of the crossing position.

Edge Type

An example showing how the built-in edge types behave.

There are four built-in edge types:

Regular
A normal crossing, a rope goes above the other one. The gap feature is the distance between the two ends of the rope going under.
Inverted
Like regular but the which rope goes above in inverted.
Wall
The ropes follow the edge without crossing. Gap controls how far they pass from the edge center.
Hole
The ropes turn back without crossing. Gap controls how far they pass from the edge center.
