MemberDescription
Network Removes zero length segments (zero in 2 dimensions), merges parts at endpoints that only connect to each other, re-orients segments that are pointing against the prevailing orientation for a part. Creates new parts for discontiguous segments or segments with different attributes. For a pair of segments in a part that share an endpoint such that one segment has NaN attributes and the other has non-NaN attributes, assign the non-NaN attributes of one to the corresponding NaN slots of the other. Equivalent to IPolyine SimplifyNetwork.
NonplanarNonplanar: Removes zero length segments (zero in 2 dimensions), re-orients segments that are pointing against the prevailing orientation for a part. Creates new parts for non-contiguous segments or segments with different attributes. For a pair of segments in a part that share an endpoint such that one segment has NaN attributes and the other has non-NaN attributes, assign the non-NaN attributes of one to the corresponding NaN slots of the other. This method is similar to Network, except parts are not merged where an end point is shared. Equivalent to IPolyline6 SimplifyNonPlanar.
Planar Force planar simplification on to a polyline that is m-aware. If a polyline is m-aware, planar simplification will not attempt to detect self-intersections, overlaps, etc. Equivalent to IPolyline4 SimplifyEx(planarSimplify=true).
