Add Point at Intersection Tool

What it Does

Adds a point where two lines, curves or circles cross. It gives you an exact spot to measure from or draw to.

Use this when two parts of your draft cross and you need a point at the crossing.

When the two items cross only once, you can also cut one of them in two at the new point.

How to Use

1. Activate the tool by selecting the Add Point at Intersection icon
2. Select the first line, curve or circle. It turns red
3. Select the second line, curve or circle, then select Continue. The second item turns blue
4. If the items cross once, choose how to save:
   • Save keeps the new point
   • Save & Split Red keeps the point and cuts the red item (your first choice) in two at the point
   • Save & Split Blue keeps the point and cuts the blue item (your second choice) in two at the point
5. If the items cross more than once, a point is added at every crossing. Select Save to keep them
6. Before you save, you can enter a name for the new point and choose its style
7. Select Cancel to leave without adding anything

A circle cannot be cut, so there is no Save & Split button for a circle.

warning

The two items must cross. If they do not, the tool tells you no point can be added. Select Cancel and start again.

info

A line or curve with no end points cannot be cut. The tool tells you, and you can select Cancel.

🧠Memorization

When you memorize a draft, avoid crossings that give more than one point. They can cause problems when the draft is recalled.
