How To Make A Cylinder In Blender

Learning how to make a cylinder in Blender is one of the very first skills you’ll need for 3D modeling. This basic shape is the foundation for so many objects, from cups and pillars to robot arms and wheels. Let’s get started with a simple, clear tutorial that will have you creating and editing cylinders in no time.

Creating a cylinder is a straightforward process that uses Blender’s built-in mesh primitives. We’ll begin with the absolute basics and then move on to controlling its initial properties. First, you need to open Blender. When you start, you’ll see a default scene with a cube, a camera, and a light. We’ll be replacing that cube.

Step-by-Step: Your First Cylinder

Press the X or Delete key on your keyboard to delete the default cube. Click “Delete” in the confirmation pop-up.
Move your cursor to the center of the 3D Viewport, which is where your grid is.
Open the Add menu. You can do this by clicking “Add” in the top menu bar, pressing Shift + A on your keyboard, or simply right-clicking in the viewport.
Hover over Mesh in the menu that appears.
From the list of mesh shapes, click on Cylinder.

Congratulations! A cylinder will now appear at the location of your 3D cursor. It will likely be selected, shown by an orange outline. You’ve just made your first cylinder. However, you might have noticed a small pop-up menu in the bottom-left corner of the viewport. That’s the operator panel for the cylinder, and it’s where the real control begins.

Understanding the Cylinder Operator Panel

Immediately after adding the cylinder, you can adjust its fundamental parameters before confirming the shape. If you clicked away and the menu disappeared, you can usually reopen it by clicking the tiny arrow in the bottom-left of the 3D viewport. Here’s what each setting does:

Vertices: This controls the number of points around the circular face. The default is 32, which gives a very smooth circle. A lower number, like 8, creates an octagonal prism. A value of 3 makes a triangular prism.
Radius: This sets the size of the cylinder’s circular faces.
Depth: This determines the height (or length) of the cylinder.
Cap Fill Type: This decides how the top and bottom circular faces are closed. “Triangle Fan” is the default. “Ngon” creates a single face, which is often cleaner for modeling.

You can tab into these fields and type new values, or click and drag the blue dots to interactively change them. Play with these settings to see the instant feedback. For most basic purposes, setting “Cap Fill Type” to “Ngon” is a good habit.

Basic Manipulation: Move, Rotate, and Scale

Once your cylinder is placed, you’ll need to position it. This uses the three core transform tools. Make sure your cylinder is selected (orange outline).

Move (Grab): Press the G key. Now move your mouse to slide the cylinder around. To move it precisely along one axis, press G then X, Y, or Z. Click to confirm, or press Enter.
Rotate: Press the R key. Move your mouse to spin the cylinder. For axis-specific rotation, press R then X, Y, or Z.
Scale: Press the S key. Move your mouse to resize the cylinder. To scale only one dimension, like making it taller, press S then Z.

You can also use the manipulator widget in the top-right of the viewport. The red, green, and blue arrows are for moving, the arcs are for rotating, and the small cubes are for scaling. Click and drag on them.

Editing Your Cylinder in Edit Mode

The real power of Blender comes from Edit Mode, where you manipulate the individual vertices, edges, and faces of your mesh. To enter Edit Mode, select your cylinder and press the Tab key. You’ll see the mesh turn yellow, showing its wireframe. At the top-left, you can switch between selecting Vertices, Edges, or Faces.

Common Edit Mode Operations for Cylinders

Selecting the Cap: Switch to Face select mode. Hold Shift and click on the top and bottom NGon faces. You can now extrude or delete them.
Extruding: With a face or edge selected, press E to extrude. This is how you, for example, pull a handle out from the side of a mug. Try selecting the top face, pressing E, then Z to extrude it upward to create a pipe.
Insetting: Select a face and press I. This creates a smaller, inset face within the original. Great for creating recessed areas.
Loop Cuts: Press Ctrl + R and hover over the cylinder. A purple loop will appear. Scroll your mouse wheel to add more parallel loops, then click to confirm. This adds new edge loops for more detail.

Remember to press Tab again to exit Edit Mode and return to Object Mode when your done editing the structure.

Using Modifiers to Enhance Your Cylinder

Modifiers are non-destructive tools that automatically add effects or complex geometry. You find them in the wrench icon tab in the Properties panel on the right. Two are especially useful for cylinders.

The Subdivision Surface Modifier

This modifier smooths your mesh. Add it by clicking “Add Modifier” and choosing “Subdivision Surface.” It will instantly make your low-poly cylinder look like a smooth, high-resolution object. Increase the “Viewport” levels to see the effect. Use this to create smooth, organic shapes from a basic cylinder.

The Bevel Modifier

This add rounded edges, which is critical for realistic modeling because real objects rarely have perfectly sharp corners. Add a Bevel modifier. Adjust the “Amount” to control the size of the bevel. You can limit the effect to only certain edges by changing the “Limit Method,” often to “Angle.” This gives your cylinder a more finished, professional look.

Practical Project: Create a Simple Drinking Glass

Let’s use what we’ve learned to model a basic glass. This will reinforce the steps for how to make a cylinder in Blender and edit it.

Delete the default cube and add a cylinder (Shift + A > Mesh > Cylinder).
In the operator panel, set Vertices to 32 (for smoothness) and Cap Fill Type to “Ngon.”
Press Tab to enter Edit Mode. Make sure you’re in Face select mode.
Select the top Ngon face of the cylinder.
Press I to inset. Move your mouse slightly inward and click to confirm. This creates the rim of the glass.
With the inset face still selected, press E then immediately press S to start extruding and scaling. Scale it inward a bit to make the inside of the glass narrower than the top.
Now press E then Z and move the mouse down to extrude the face downward, creating the hollow interior. Don’t go all the way to the bottom.
Select the bottom face of the interior and scale it down slightly (S).
Press Tab to exit Edit Mode. Add a Subdivision Surface modifier to smooth it out. You might need to add a slight Bevel modifier to the rim for realism.

You now have a simple glass! You can add a material to make it look like glass in the Shading workspace.

Advanced Tips & Common Mistakes

As you practice, you’ll encounter a few common issues. Here’s how to solve them.

Why Does My Cylinder Look Blocky?

This is usually because the Vertex count is too low. In Edit Mode, you can’t directly change this, so it’s best to get it right when you first add the cylinder. If you already have one, you can use the Subdivision Surface modifier to smooth it, or you can manually add edge loops with Ctrl + R. Sometimes, applying a Subdivision Surface modifier (by clicking the downward arrow in the modifier and choosing “Apply”) will give you more geometry to work with.

Fixing Dark Shading and Sharp Edges

Cylinders, especially with low vertex counts, can have weird dark shading. This is often due to “flat” shading on curved surfaces. In Object Mode, right-click your cylinder and choose “Shade Smooth.” Instantly, it will look much more like a round object. For sharp edges you want to keep, you can add custom “Split Normals” or use the “Auto Smooth” option in the Object Data Properties tab (green triangle icon).

Merging Vertices for a Cleaner Mesh

If you’ve extruded and scaled faces, you might end up with vertices very close together. This can cause rendering issues. In Edit Mode, you can select all vertices with A, then press M and choose “By Distance.” This merges vertices that are extremely close, cleaning up your mesh.

Applying Scale and Other Transforms

This is a crucial step before doing more advanced work. If you’ve scaled your cylinder non-uniformly (like making it taller with S-Z), the scale values in the N-panel (press N to toggle) won’t be 1.000. This can cause modifiers and further edits to behave strangely. Always apply your scale. With the object selected, press Ctrl + A and choose “Scale.” This sets the visual scale to 1.000 while keeping the object the same size. Do this for Rotation and Location too if needed.

FAQ Section

How do I make a hollow cylinder in Blender?

You have two main methods. First, in Edit Mode, select the top and bottom faces and press I to inset, then E to extrude them inward. Second, you can use the “Solidify” modifier, which adds thickness to all faces, instantly making a solid cylinder hollow with a wall thickness you control.

How do you change the sides of a cylinder in Blender?

The number of sides is set by the “Vertices” parameter when you first add the cylinder. To change it later, you might need to use a workaround. One method is to add a new cylinder with the desired vertex count and delete the old one. For more complex changes, the “To Sphere” transform (in Edit Mode, select all and press Shift + Alt + S) can sometimes help adjust roundness.

What is the shortcut for cylinder in Blender?

There isn’t a single-key shortcut. The standard workflow is to press Shift + A to open the Add menu, then navigate to Mesh > Cylinder. This is the quickest method once you memorize the key press.

How do I cap a cylinder in Blender?

If you have an open-ended cylinder (like a pipe), you can cap it in Edit Mode. Select the open edge loop by holding Alt and clicking on one of its edges. Then press F to fill it with an Ngon. For a more segmented cap, with the edge loop selected, press E to extrude and immediately press S to scale to zero, then press Alt + M and choose “At Center” to merge all the new vertices into one central point, creating a triangulated cap.

Conclusion

Mastering the cylinder is a fundamental step in your Blender journey. You’ve learned not just how to add one, but how to control its initial properties, manipulate it in 3D space, and edit its underlying geometry to create more complex forms. From a simple glass to a complex mechanical part, the techniques of extrusion, inset, and loop cuts are universal. Remember to use modifiers like Subdivision Surface and Bevel for polish, and always apply your scale before serious modeling. Now that you know how to make a cylinder in Blender and shape it, you have a powerful tool for building almost anything. The next time you model, start with a cylinder and see where your edits take you—it’s the perfect building block for countless creations.
