formZ SDK | 5.0 API Reference | Project | Modeling | Objects | Topology
Description
Returns the index of the next segment of a given segment.
The model_type parameter determines whether the segment
is taken from the facetted or smooth topology.
model_type must be specified.
If the curve to which the segment belongs is an open wire and the
given segment is the last segment, next is returned as -1.
Recall, that an open wire in the facetted topology has a dummy
segment at the end.
For example, a wire which appears with two segments on the screen
is composed of three segments.
This last dummy segment holds the point index for the end
point of the previous to last segment.
In the smooth topology there is no dummy segment,
as each segment stores start and end point indices.
