SubDEdgeChainTrimToRange Method

Trims the chain down to the run of edges between firstEdge and lastEdge, removing everything before firstEdge and everything after lastEdge.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 8.36
Syntax
Copy
public uint TrimToRange(
	SubDEdge firstEdge,
	SubDEdge lastEdge
)

Parameters

firstEdge
Type: Rhino.GeometrySubDEdge
The edge to keep as the new start of the chain. Pass null to keep the current start.
lastEdge
Type: Rhino.GeometrySubDEdge
The edge to keep as the new end of the chain. Pass null to keep the current end.

Return Value

Type: UInt32
The number of edges that were removed.
Remarks
This wraps ON_SubDEdgeChain::RemoveEdges, whose name reads as though the given range is what gets removed. It is the other way round: the range is what survives. Passing null for both edges therefore removes nothing and returns 0; use Clear to empty the chain.
