#Break

Clicking a line splits it in two at the point of the click.

#When you need it

• To give one half its own dimension: while the segment is one, a dimension sets its whole length.
• To delete the middle of a segment without touching its ends.
• To free a stretch for a corner fillet or a chamfer.
• To insert an arc between the halves without redrawing the outline.

#What happens to the constraints

Both halves inherit the constraints of the original line, and a coincidence of the ends appears at the break point. It keeps the outline closed: to pull the halves apart, remove that coincidence — otherwise they move together.

#How it differs from trim

Trim removes a piece. Break removes nothing — it splits one entity into two, leaving both where they were. Visually nothing changes after a break: the line looks exactly as before.

It is easy to check — click one half: only that half gets selected.
