How to Join and Separate Objects in Blender

By GameDevTraum

Introduction

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.

in the outliner of blender you can see the two separate objects that we are going to join
Fig. 2: In Blender’s Outliner we can see that these are two different 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.

the join option allows you to join two objects in blender
Fig. 3: Select both objects, right click and use the “Join” option.

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.

To separate two objects in Blender we select all the vertices of the object we want to separate

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.

To separate two objects in Blender we use the separate menu, quick access with the letter p
Fig. 6: Right click and go to the “Split” option. You can also use the menu shortcut to separate objects with the letter “P”.

In figure 8 we see that we now have two different objects in the Outliner.
