The Trim to Length command on the shortcut menu that appears when you right-click a sketch trims the length of the sketch using an exact distance measurement. The value entered will be the new length of the sketch. The length is given in map units by default. You can also give the length in other units by specifying a distance units abbreviation with the value that you enter.
- Click the Edit tool
on the Editor toolbar and double-click the feature you want to edit.
- Right-click any part of the line and click Trim to Length.
- Type the length to trim the line (beginning at the last vertex marked in red) and press ENTER.
The length is trimmed. You can flip a line to trim it from the first vertex instead of the last.
- Right-click anywhere on the map and click Finish Sketch.
