A node forms begin and end of a Segment.
A Node can define a Folding_direction. It specifies the direction into which the Node and its adjacent branch is folded in the finished harness product. This definition is necessary for example for end splices, where the splice is placed on a short branch, that is folded into / onto another segment after the assembly of the splice. In the finished product, such branches are cover by the the Wire_protection that covers the Segment into which the branch is folded.
For the sake of a clear interpretation, the following restrictions apply:
- A branch is a linear subset of the topology (Node -> Segment -> Node -> Segment -> Node ->...), with at least one segment. No splitting or branching is allowed.
- A Folding_direction shall be defined only for Nodes that are at the end of a branch (The Node is only referenced by 1 Segment).
- The branch is folded completely into the direction defined by the Folding_direction .All Segments starting at the Node defining the Folding_direction, till the first Node that has more than two Segments pointing to it. This Node is the beginning of the branch.
- The Segment referenced in the Folding_direction shall be a Segment that is adjacent to the Node where the branch is beginning.
The id specifies the identifier of the Node.
The alias_id specifies additional identifiers for the Node. Example: Node Ids may vary from one CAD system export to another. Therefore the CAD system Id is improper for Id attribute. Id shall have a value which is unique within the harness. Alias_id may be used for the CAD system Id.
The bend_radius specifies the maximum bend radius at the Node. Example: May be used for the routing of fibre-optics.
Defines the direction (Segment) in which this Node will be folded (see Description of Node).
