Description

AddSegments is a BoundaryModifier, used as the modifier argument of the OOF.Skeleton.Boundary.Modify command when editing Skeleton boundaries. It adds a set of Segments to the boundary specified in the boundary argument of the Modify command. The boundary must be an edge boundary.

The group parameter specifies which Segments are to be added to the boundary. It must be either the name of a Segment group or the special placeholder object, selection, referring to the currently selected Skeleton Segments.

Edge boundaries must be constructed from a single contiguous non-branching set of Segments, and they must be directed. Boundary conditions use the direction to determine the boundary normal and the direction of applied Fields and Fluxes. The direction parameter specifies the direction of the boundary being created. Adding Segments to an edge boundary does not change the direction of the existing boundary.

It is an error to attempt to add Segments to a closed boundary, or to add Segments anywhere other than at the ends of a open boundary. See Figure 6.58 for examples.

Figure 6.58. Adding Segments to a Boundary

An existing boundary (in orange) and some selected Segments (in green).

The boundary created by adding the selected Segments. The direction of the boundary is determined by the direction of the old one.

None of the groups of selected green Segments can be added to the existing boundary. (a) doesn't form a unique directed sequence, (b) doesn't attach to an end of the existing boundary, and (c) doesn't attach at all.

This set of green Segments can be added, converting an open boundary to a closed one.
