Manipulating Break Points
When you add break points in a CL file listing, the system indicates them by placing a red downward arrow to the left of the appropriate CL line. When you play the tool path, the tool stops upon reaching the break point line in the CL data listing.
To display the tool motion without stopping at break points, click NCL File > Suppress all break points. The break point information, however, will be retained; when you click NCL File > Resume all break points, all the break points will reappear.
To delete an existing break point, select the appropriate line in the CL data listing, then click NCL File > Delete break point.
