Command : SKETCH
A freehand sketch consists of a series of straight line segments, created either as individual line entities or as a polyline. Before you begin creating a freehand sketch, you must set the length, or increment, of each segment. The smaller the segments, the more accurate your sketch, but small segments increase the file size.
After you specify the length of the sketch segments, the crosshairs change to a pencil tool ().
A freehand sketch line is not added to the drawing until you "write" the sketch into your drawing.

Do one of the following:
- In the command bar type skpoly , then press Enter.
- In the Settings dialog, go to Drawing > Drafting > Entity Creation > Freehand Sketches .
