Controls on the edit bar allow you to specify the real world width of a sketch polyline prior to creating it. Selecting an existing sketch polyline displays similar controls that allow you to change its type or width. The Polyline Sketch Units value on the Drawing page of the Drawing Options dialog box determines how closely sketch polylines follow your mouse movement. This value specifies how many pixels of movement occur before AutoSketch adds another vertex to the sketch polyline. Smaller values produce a finer sketch with more vertices in the polyline. Larger values result in rougher sketches and a simpler entity. The default number is 8. Increasing the number creates longer segments that take up less memory. To draw a "freehand" polyline 1 On the Draw menu, click Polyline, Sketch, or click the Sketch Polyline button on the All-In-One toolbar. 2 (optional) Change the Width setting on the edit bar. 3 Click a point where you want the polyline to begin, then drag. As long as you hold the left mouse button down, segments are added to the polyline. 4 Release the mouse button. To change sketch precision 1 On the Tools menu, click Drawing Options. The Drawing Options dialog box appears. 2 Click the Drawing page tab. 3 Change the number in the Polyline Sketch Units drop-down list box. Lower values increase the accuracy of the sketch polyline. 4 Click OK. 142 | Chapter 12 Polylines, Polygons, & Curves
