How To Subdivide In Blender? (3 Different Methods)

This is the final way we will subdivide the object in a blender. To do that, let’s click on add modifier icon in the builder’s right corner. Once you hit the icon, scroll down to find the subdivision surface modifier. As you can see, both the add modifier and the subdivision surface are in the picture below.

Once you click on the subdivision surface, it will make the subdivisions and round the object. The regular cube in the early picture will turn into something like this. Check the picture below.

At the same time, once you click the subdivision surface, you will also get a new window (below picture) in the right corner. The option is now set to Catmul-Clark; that’s why the object appeared as a rounded cube. 

But if you set this option to simple, you will get the regular cube. Also, as you can see,  the two different settings below the Catmull and simple. One for the viewport and one for the render. 

The Level Viewport and render options are the two different settings for the level. That’s how you get more geometry by using the modifier tool in the blender.

Can I Use Shortcuts to Subdivide in Blender?

Yes, you can use shortcuts to subdivide, but this time you are no longer in edit mode but in object mode. 

As you know, you can add a subdivision surface modifier. You can add it real quick. For that, you have to use a shortcut. Simply select the object and press Ctrl+1, which is subdivision level 1.

For the next level, press  Ctrl+2 and so on. You can go up to Ctrl+5. You can simultaneously add a subdivision surface modifier to all the selected objects. Once you click the subdivision surface modifier, you get the following window. (see the picture below).

With the shortcut, you can adjust only the viewport level. If you press Ctrl+5, the viewport level will be 5, but the render will remain the same. This is how the shortcuts work.

Can I Undo or Un-subdivide An Object in Blender?

So far, we have subdivided the model several times and created more patterns. However, we may only like some of them. So in this part, we will see how to reverse the operation and remove shapes we don’t like. 

Step 1: First, we will subdivide the object by selecting the decimate option under the modifier tab. See the picture below.

Step 2: Once you select the decimate icon, the window (see the picture below) appears with multiple options. These options include collapse, unsubdivide, and planner.

Step 3: To unsubdivide, switch from the collapse option to the unsubdivide option. Once you select the unsubdivide option, you get the new window  (see the picture below). In the picture below, the iteration is 0, and the number of faces of the model is 6 (in our case, it is a regular cube).

Step 4: All you have to do is increase the iterations, which will unsubdivide. In our case, we have increased the iterations from 0 to 2. Which results in a lower number of face counts.

Once we have increased the iterations, the regular cube with 6 faces turns into the new geometry with 4 faces.
