To weed or add vertices to a 3D polyline
1 Click Tools tab ➤ Map Edit panel ➤ Clean Up.
2 On the Select Objects page, select the 3D polylines from which to remove
extra vertices or add vertices. Click Next.
3 On the Select Actions page, in the Cleanup Actions list, click Weed
Polylines. Click Add >.
NOTE Run Weed Polylines by itself (without other cleanup actions). If you
run it with other actions, Weed Polylines runs only once, regardless of how
many times it is listed in the Selected Actions list, and it always runs before
other actions, regardless of its position in the list.
4 In the Select Actions list, click Weed Polylines to display the Cleanup
Parameters for this action.
5 Under Weeding Factors, enter the weeding distance in the Distance box,
or click Pick and use your pointing device to specify distance by selecting
two locations in the drawing.
6 For Angle, enter the deflection angle, or click Pick to specify the angle
by selecting a starting point, a vertex, and an ending point.
■ A point on a 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 Distance value, and the deflection
angle is less than the weeding Angle value, then the middle point is
weeded out.
■ A larger distance and deflection angle weeds a greater number of
points.
■ The weeding distance must be less than the supplementing distance.
■ When using Pick to specify measurements, measurements are displayed
dynamically using a tooltip. The format and precision of the
measurements are determined by the UNITS command.
7 Under Supplementing Factors, enter the supplementing Distance, or click
Pick to specify distance in the drawing.
The supplementing distance is the maximum distance between vertices.
If the distance between vertices on a contour is greater than the
supplementing factor, then points are added along the contour at equal
