Sometimes in Blender, an object you're modeling is too complicated to model in a single object, so it's easier to make two (or more) objects and then merge them together later. However, it's only easier if you know how! Here's how to merge together objects in three different ways.
This is the easiest process we’ll look at. Though one of the most commonly used tools, it doesn’t work the way a lot of people expect.
Joining objects does not geometrically connect them together. It simply “marks” them as one object. This means they move, rotate, scale, and animate like one object, but they are not attached. So if you 3D-print an object “joined” in Blender, it wouldn’t print as one object. Rather, the result would be multiple objects.
That said, joining is still incredibly useful for working with complex scenery or characters, or when working with a print that must be assembled. You can join the pieces in their assembled state, and then have them printed individually.
Before joining objects, there are a couple of things to understand:
Here’s how to join two or more objects:
This is a very handy tool to have, but what if we really need to connect two objects together? Not to worry! Though it requires more steps, it’s still rather simple.
If you need to attach two objects together, joining them obviously won’t work. However, using modifiers, we can achieve just that with minimal effort! Again, you’re going to need to choose a prominent object. Also, this method only works with two objects, so if you have more than two objects to attach, then simply repeat the process for each extra object.
Here’s how to add two objects together:
Once you’re ready, scroll down to the section in this article titled “Applying Modifiers” to finish the process, reducing it down to one object.
Note: This is not a method of connecting or joining two objects together. Rather, it’s a useful method of engraving or cutting an object to get rid of another.
Sometimes, you’ll find a need to cut out a piece of an object using another. This is useful in cases where you want to engrave text or a shape into an object. This can easily be done using the boolean modifier.
Here’s how to subtract one object from another:
Once you’re ready, move on to the next section to finish the process.
You may have noticed that your object doesn’t yet look the way you wanted it to.
That’s because we’re not done yet! The image uses the example from the subtraction section, but the same process applies to the addition section as well.
Here’s how to apply a modifer:
And there you have it! Whether you chose to use a modifier or the join command, you now know how to merge objects together in three different ways, thus enabling you do do more with your models!
