# Split
Create points on the sketch line to break the sketch line.
What to do
1.Click on the split command to bring up the dialog box.
2.Click on the sketch line, the line segment breaks into two lines from the click position, the constraint is automatically added between the broken sketch lines,and the user can manually remove this constraint.
3.Different sketch lines add different constraints, and the corresponding relationship is as follows:
| Type | Interrupting elements | Added constraints | ICONS |
|---|---|---|---|
| Unclosed curve | Arc | Equal |  |
| Unclosed curve | Spline curve | tangency |  |
| Unclosed curve | Straight lines | Collinear |  |
| Closed curve | Full circle | congruent |  |
| Closed curve | Closed spline curve | No constraints added |  |
4.End the command by the ESC key, or "Close" in the command bar.
