Place Stream Line String

Use it!

Used to place a stream line string — primarily for tracing images when Digitizing. Many vertices can be defined without having to enter a large number of individual data points.

The movement of the pointer is sampled, and data points are recorded based on the tool settings:

Tool SettingEffect
Delta

Sets the minimum distance, in working units, between sampled points.

Tolerance

Sets the maximum distance, in working units, between recorded data points.

Angle

Sets the angle, in degrees, that when exceeded, causes the last sampled point to be recorded as a data point.

Area

Sets the area that, when exceeded, causes a sampled point to be recorded as a data point.

To place a stream line string
  1. Select the Place Stream Line String tool.

  2. Enter a data point to define the origin.

  3. Move the pointer. A stream of data points is entered without pressing the Data button.

  4. Reset to end the line string.

Key-in: PLACE LSTRING STREAM

A line string element can have a maximum of 5000 vertices. If more than 5000 vertices are defined, a complex chain consisting of one or more line string elements is created.

The tool settings can also be set in the DGN File Settings box (Settings menu > Design File…), in the Stream category.

To place a stream curve, use the Place Point or Stream Curve tool.
