If a fence is drawn, choose from: Inside, Overlap, Void or Void-Overlap.

If no fence is drawn, the setting is not available.

Use to select the type of generalization that will be performed.

• Stream Parameters — This method uses the same parameters to simplify the polyline as the MicroStation Place Stream tool.

• Douglas-Peucker — This is perhaps the most popular method to reduce points from a polyline. It excludes points that deviate more than the set tolerance from the baseline connecting 2 neighboring points. With a polyline composed of points A, B and C. If the distance of point B from the Segment A to C is greater than the tolerance, point B will be removed from the polyline.

Use to enter the delta factor. Sets the minimum distance, in working units, between points of the polyline.

Use to enter the tolerance factor. Sets the maximum distance, in working units, between points.

Use to enter the angle factor. Sets the angle in degrees.

Sets the area that, when exceeded, causes a sampled point to be kept. The pertinent area is the triangle formed by extending a line between each of the last two recorded data points and the sampled point. Units are square master units, and the value must be specified as a floating point number (for example, 110.0 or 1.1E2).
