Merge Lines & Curves Tool

What it Does

Joins two lines or curves that meet at a point into one single line. The new line follows the same path as the two originals.

Use this when you want to treat two connected pieces as one, for example to measure them together or to give them one name.

The two items must share an end point. If they do not, the tool tells you, and you need to select Cancel and choose two that meet. The result is always a line made of straight segments (a polyline) that follows the shape of the originals. If either item is a curve, it is turned into a polyline first. Its curve points are removed, so you can no longer reshape it with Move Curve Points. A warning tells you before this happens.

How to Use

1. Activate the tool by clicking the Merge Lines & Curves icon
2. Select the two lines or curves to join, then select Continue
3. If either item is a curve, a warning tells you it will no longer be a curve you can reshape. Select Merge to go on, or Cancel to keep everything as it was
4. Enter a name for the new line in the Name box
5. Choose a color for the new line if you want one
6. Select Save to keep the merged line, or Cancel to leave without changing anything

warning

The two original lines or curves are replaced by the new line. If no other line or curve uses the shared point, that point is removed too.

info

The Merge Curves Tool works the same way.

🧠Memorization

When you memorize a draft, the merge is remembered along with the name and color you chose. So is the change of any curve into a polyline.
