Match lines are deleted automatically when you delete a view frame or view frame group.
After match lines are created, the only way to delete them is to delete the view frame, or view frame group object they belong to.
If you explode one or more match lines or view frames, all match lines and view frames in that view frame group are exploded, and the following objects are deleted: match lines, view frames, view frame group.
You can delete match line labels. Selecting any match line label automatically selects all match line labels in that view frame group. To delete them individually, select them by using Ctrl + click, and then press the Delete key.
If you do not want match lines to appear in the drawing, change the display style so that the match line component’s visibility is turned off.
