Beta (Inputs.Base)BetacurveThe index of the curve, among the node's curves.
BetastartThe index of the vertex the edge starts at.
BetaendThe index of the vertex the edge ends at; the same as start for a closed edge, such as a
whole circle.
Optional BetasameWhether the edge runs from start to end the way the curve runs; left out, it does.
A closed edge with no parameters takes the whole curve.
Optional BetaparametersThe curve's parameters at the start and the end; left out, they are found from the vertices.
An edge of a brep node: the part of a curve between two vertices. Faces that meet along an edge name the same edge.
