Weed Polylines
Use Weed Polylines to add and remove vertices on 3D polylines. This is helpful
to control the drawing file size and contour appearance, or to remove
redundant information.
NOTE This functionality is for drawing objects only. There is no equivalent for
geospatial feature data.
Enter Weeding Factors and Supplementing Factors to determine if a vertex
should be added or removed from the 3D polyline.
Weeding Factors
Use Weeding Factors to reduce the number of points generated along 3D
polylines. Weeding factors ignore vertices that are closer together than the
Distance factor and that deflect less than the Angle factor. A larger distance
and deflection angle weeds a greater number of points. The distance factor is
measured in linear units and the angle factor is measured in angular units.
Weeding Factors must be less than Supplementing Factors.
A point on the 3D polyline is weeded by calculating its location in relation
to the vertices before and after it. If the length between these three points is
less than the weeding length value, and the deflection angle is less than the
weeding angle value, then the middle point is not added to the contour data
file.
