This will toggle on and off the Flex Cut Marks for a Flex path. Cut Marks show where the modules can be cut to terminate a run properly.

To be clear: a flex tube can only be cut at the Cut Marks; you cannot cut it anywhere. Most flex tubes will have lines on the back or side at each cutting distance. This is the definitive spot where you can cut.

Some tubes do have a small amount of linear flexibility, that over a long distance, can impact the exact position of the cutting position.

The software will only draw tubes according to the cut marks. The underlying vector path, however, can extend beyond the tube. When this path extends past the distance of one cut mark, then the tube will be drawn for that section.
