Join Command in AutoCAD
In AutoCAD, the Join command is used to join the objects end to end to form a single entity. Depending on the requirements, the objects might be curved or straight.
It creates a single 2D or 3D object by combining a succession of linear and curved objects.
To link any item, follow these steps.
Let's have a look at how to link any line or object.
The steps are as follows:
- Select the Join command from the Modify interface's ribbon panel.
Or
On the command line, type J or join and hit Enter.
- To link numerous items, we must first choose them. The selected items are all linked at the same time.
- Enter
The chosen objects will be fused together to form a single unbreakable object.
Consider the following scenario.
Example:
We shall discuss this in this section.
We are required to join the segments numbered 1, 2, 3, and 4. These segments are shown below:
To join the segments marked above, follow these steps:
- On the command line or at the command prompt, type J or join and hit Enter.
- Segments 1 and 2 should be chosen.
- Press the Enter key.
- 3 and 4 segments should be chosen.
- Enter.
As illustrated in the figure below, the portions will be connected together:
The following are the types of objects that can be joined with the JOIN command:
1. Lines
Only the source line can be linked to the line objects.
There is no restriction on the amount of space between the points on the line.
The lines' terminals should be parallel to the straight line. The following graphic explains it:
We can also make a single line out of the series of lines.
The initial and last segments of the series must be specified here.
The following graphic depicts the above procedure:
2.Arcs
Only the source arc can be linked to the arcs. The arc's radius and canter point must be the same. There may be gaps between the arc's segments. Consider the following scenario.
The image is as follows:
3.Polyline
To the source arc, lines, arcs, and polylines can be linked.
Elliptical Arcs are a type of elliptical arc.
Only the chosen elliptical arc can be linked to the elliptical arcs. The elliptical arc's major and minor axes must be the same. The arc should be parallel to the ground. Space between the elliptical arcs is possible.
4.Polylines in three dimensions
The provided 3D Polyline can be linked to the linear or curved object. The objects should be contiguous and noncoplanar.
5.Helixes
The specified helix can be attached to the linear or curved object. The objects should be contiguous and noncoplanar.
6.Splines
The chosen spline can be linked to the linear or curved object. The objects should be contiguous and noncoplanar.
- Multiple items can be joined at the same time.
- Without specifying a source object, joins multiple items. The following are the rules and the resulting object types:
- Collinear lines are joined to form a line object. There may be gaps between the endpoints of the lines.
- Coplanar arcs with the same center point and radius are joined to form an arc or circle object. There may be gaps between the endpoints of the arcs. The lengthening happens in a clockwise manner. If the linked arcs create a complete circle, the result is a circle object.
- Joining splines, elliptical arcs, or helixes together, or to other objects, produces a spline object. Non coplanar objects are possible.
- Joining coplanar lines, arcs, polylines, or 3D polylines yields a polyline object.
- Joining noncoplanar items that aren't curved produces a 3D polyline.
In AutoCAD, how do you attach lines to polylines?
According to the position of the line and polyline, there are two conditions.
Examine your situation and take the following steps:
In AutoCAD, condition 1 is to join lines to polylines.
1) Both the line and the polyline are at a 0 degree angle (Straight).
2) Select Modify panel from the drop-down option. Then choose the "Join" command. Alternatively, put "JOIN" in the command bar and hit Enter.
3) Then, one by one, right-click each line and polyline.
4) Both lines will come together.
