Join command in AutoCAD

Join

The Join command in AutoCAD is used to join the objects end to end to create a single object. The objects can be curved or linear, depending on the requirements.

It combines the series of linear and curved to create a single 2D or 3D object.

Note: The objects namely, rays, closed objects, and construction lines cannot be joined using the Join command

Steps to join any object

Let's discuss steps to join any line or object.

The steps are listed below:

  1. Select the Join command from the ribbon panel under the Modify interface.

    Or
    Type J or join on the command line and press Enter.
  2. We need to select multiple objects to join. The selected objects are joined at once.
  3. Press Enter.

The selected objects will be joined as a single unbreakable object.

Note: Only the collinear objects can be joined. It means that the objects lying on a straight line will be joined.

Let's consider an example.

Example:

Here, we will consider the below figure.

We are required to join the segments numbered 1, 2, 3, and 4. These segments are shown below:

The steps to join the segments markedabove are:

  1. Type J or join on the command line or command prompt and press Enter.
  2. Select segments 1 and 2.
  3. Press Enter
  4. Select segments 3 and 4.
  5. Press Enter.

The segments will be joined, as shown in the below image:

The types of objects that can be joined using the JOIN command are listed below:

  • Lines
    The line objects can only be joined to the source line.
    The line can have space between them.

The endpoints of the lines should lie on the straight line. It is explained in the below image:

We can also join the series of lines in a single line.

Here, we need to specify the first and last segment of the series to join.

The above process is explained in the below image:

  • Arcs
    The arcs can only be joined to the source arc. The radius and center point of the arc must be same. The arc can have spaces between them. Let's consider an example.
    The image is shown below:

  • Polyline
    Here, lines, arcs, and polylines can be joined to the source arc.
  • Elliptical Arcs
    The elliptical arcs can only be joined to the specified elliptical arc. The major and minor axis of the elliptical arc must be same. The arc should be coplanar. The elliptical arcs can have space between them.

  • 3D Polylines
    The linear or curved object can be joined to the specified 3D Polyline. The objects should be noncoplanar and contiguous.
  • Helixes
    The linear or curved object can be joined to the specified helix. The objects should be noncoplanar and contiguous.
  • Splines
    The linear or curved object can be joined to the specified spline. The objects should be noncoplanar and contiguous.
