Lines made up of many small segments can result in large files and slow operation. Such lines can be simplified to fewer segments. This is often useful after importing shapes from other sources.
- Select the line.
- On the status bar view the number of segments.
- Choose Line | Transform | Simplify and enter the desired tolerance which indicates how far you will permit the converted line to deviate from the original line (large values will simplify the line the most).
- Click OK.
- To see the simplification choose Line | Ungroup and click on segments.
To simplify a line optimally draw a new line over the old one and delete the old lines. The spline feature is often helpful for this.
