Problem

Is there a "free-hand" drawing or "tracing" functionality available in MicroStation?

Solution

Yes, the Place Stream Line String tool allows a user to place a line string in a "free-hand" or "tracing" manner similar to how you would draw with a pencil or paint brush.
This tool is commonly used for tracing images or drawing when Digitizing.
Many vertices can be defined without having to enter a large number of data points. The resulting line string will be vectorized with data points for future editing.
The tool can be found in the Drawing Workflow > Home Tab > Placement Ribbon Group > Place Multi-line Split Button

When using the tool, the movement of the pointer is sampled, and data points are recorded based on the tool settings.
There are 4 options contained in the tool settings:

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

Notes to keep in mind:
- 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 Design File Settings > Stream category
- to place a stream curve, use the Place Point or Stream Curve tool
