In this article we see how to join and separate objects in Blender. We start with two objects and unite them into one object and then we see how to separate that object into two or more objects.
Here’s a short video I made to show you how to join and separate objects in Blender.
Join Objects in Blender
We start from two separate objects as seen in figure 1, in the Outliner of figure 2 we see that they are two separate objects.
We select both objects using SHIFT and right click to display the menu shown in figure 3. We choose the option “Join” to combine both objects into one.
It is convenient to learn the shortcut CTRL+J to save time.
In the Outliner we see that we now have a single object composed of both cubes.
Separate Objects in Blender
Now we want to reverse the process, we start from a single object composed of several parts and we would like to take one of those parts and separate it into a new object.
To do this we enter the edit mode (TAB shortcut) and select all the vertices we want to separate into a new object. In the video I select a vertex of the cube and then I use the shortcut CTRL+L that allows me to select all the vertices that are connected.
Then we right click to display the menu shown in figure 6 and go to “Separate”. We can also use the shortcut with the letter “P” to display this menu.
We choose the “Selection” option to separate all the selected vertices into a new object.
In figure 8 we see that we now have two different objects in the Outliner.
