Density Multiplier: The quality of output produced by this command is directly proportional to vertex density of contour polylines. This multiplier can be used to temporarily increase contour vertex density for the duration of calculations at the cost of additional processing time. Setting this multiplier to higher values generally reduces occurrence of errors in the output.
Draw Crust Segments: Crust segments are complimentary to
skeleton segments.
Generally, crust segments will be nearly identical to existing contour
lines.
Skeletal Extraction:
Draw None: When this setting is selected, no
skeleton segments will be drawn.
Draw Ridge and valley segments:
When
this setting is selected, only skeleton segments that lie in ridges and
valleys (i.e. between two contour lines at different elevations) will
be drawn.
Summit and Pit Segments: When
this setting is selected, only skeleton segments that lie in summits
and pits (i.e. encircled by contour lines at same elevation) will be
drawn.
All Segments: When this setting is selected, all types
of skeleton segments are drawn.
Skeletal Type (Significant
and Full):
Significant skeleton segments are those segments that fall into flat
areas of the triangulation. Use this setting to reduce the number of
segments generated by this command.
Minimum Segment Count: Use
this setting to prevent small segment branches from being generated.
This can reduce occurrence of errors in the output.
Minimum Branch Length: Use
this setting to prevent small segment branches from being generated.
This can reduce occurrence of errors in the output.
Skeleton Layer: This is the layer that the skeleton polylines will be drawn in.
