To weed or add vertices to a 3D polyline
- On the Select Objects page,
select the 3D polylines from which to remove extra vertices or add
vertices. Click Next.
- 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.
- In the Select Actions list,
click Weed Polylines to display the Cleanup Parameters for
- 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.
- For Angle, enter
the deflection angle, or click Pick to specify
the angle by selecting a starting point, a vertex, and an ending
- 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
- Under Supplementing Factors,
enter the supplementing Distance,
or click Pick to specify distance in
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 intervals that are
less than or equal to the supplementing distance. The smaller the
distance, the greater the number of supplemented points.
- For Bulge, enter
the bulge factor value, or click Pick to specify
it in the drawing.
The bulge factor adds
vertices to a polyline curve, creating an approximation of the curve
using straight line segments. The bulge value is a ratio of the
distance from the arc to the chord divided by half the length of
- Continue specifying Drawing
Cleanup settings. Click Finish.
When the operation is
complete, the total number of original vertices, the total number
of vertices removed, and the number of new vertices is reported on
the command line.
