# Join

Joins the endpoints of linear and curved objects to create a single object.

Command line enter "Join" or "J"

Use JOIN to combine lines, arcs, elliptical arcs, polylines, 3D polylines, splines, and helixes by their endpoints into a single object.

The result of the join operation varies depending on the objects selected.

Typical applications include:

- Replacing two collinear lines with a single line.
- Closing the gap in a line that resulted from a BREAK.
- Completing an arc into a circle or an elliptical arc into an ellipse. To access the Close option, select a single arc or elliptical arc.
- Combining several long polylines in a topographic map.
- Joining two splines, leaving a kink between them.
- In general cases, joining objects that touch end-to-end, but that are not in the same plane result in 3D polylines and splines.

Note: You can also use the Join option of the PEDIT command to combine a series of lines, arcs, and polylines into a single polyline
