When a group of slices are cut through a mesh, no attempt is made by CySlice to align their start points (see Figure 274). However, lined up start points, and consistent direction, can be a very important requirement for lines in some applications.

Figure 274. Unmatched Start Points

Fortunately, with the help of split lines, you can make sure that a group of lines have aligned start points. First, draw a slice line using any of the methods previously described (see Figure 275).

Figure 276. Splitting

Wherever the split line crosses any other slice line, the other slice line is split. If this slice line is closed, then its start point is simply moved around to the split point (see Figure 277). However, if the slice line is open, then it will be split into two separate slice lines.

Figure 277. Pick it and Split

Finally you can hide the split line by pushing it to the Temp layer (see Figure 278). Or you could choose to delete the split line, but hiding it in the Temp layer is safer.

Figure 278. Hide the Split Line

Be warned: every unpicked line is split. If you have a group of lines that you don't want split, push them into the Temp layer until it's safe to bring them back out to the Work layer.

If you have many lines you want to split with, it's perfectly OK to pick them all and split with them all at once.
