How To Change Vertices Of Cylinder In Blender

by

Learning how to change vertices of cylinder in blender is a fundamental skill for any 3D artist. It’s the first step to moving beyond basic shapes and creating custom models. This guide will show you several methods, from simple scaling to advanced editing techniques.

You’ll find that cylinders are incredibly versatile starting points. With a few adjustments to their vertices, you can create pipes, pillars, vases, and much more. Let’s get started with the basics you need to know.

How To Change Vertices Of Cylinder In Blender

Before you change anything, you need to select the vertices. A cylinder in Blender starts with specific vertex structure. It has a circle of vertices on the top, a circle on the bottom, and vertices running down the side connecting them.

To begin editing, you must first enter Edit Mode. You can find this dropdown menu at the top of the 3D viewport. Alternatively, just press the Tab key on your keyboard to toggle between Object Mode and Edit Mode.

Selecting Vertices, Edges, and Faces

In Edit Mode, you have three selection options. You choose between vertices, edges, or faces. The buttons for this are in the top-left corner of the 3D viewport.

  • Vertex Select: Lets you pick individual points.
  • Edge Select: Allows you to choose the lines between vertices.
  • Face Select: Lets you select the filled polygons.

For changing vertices, you’ll usually use Vertex Select mode. But sometimes selecting an edge or face is quicker for affecting groups of vertices.

Basic Transformation Tools

Once vertices are selected, you use the core transformation tools. These are the same tools you use for objects.

  • Grab (G): Click and drag to move selected vertices.
  • Rotate (R): Spin the selected vertices around a point.
  • Scale (S): Make the selected vertices larger or smaller.

You can constrain these actions to an axis by pressing X, Y, or Z after pressing the tool key. For example, pressing G then Z will only move vertices up and down.

Using the 3D Cursor as a Pivot

The pivot point is crucial when scaling or rotating. By default, it’s set to the median point of your selection. But you can change it to the 3D Cursor.

This is useful for, say, scaling the top vertices of a cylinder inward to create a cone. Place your 3D cursor at the base, change the pivot point to ‘3D Cursor’, then scale the top vertices.

Practical Method 1: Creating a Tapered Cylinder

Let’s put this into practice. A common task is tapering a cylinder, like making a stylized pillar.

  1. Add a cylinder (Shift + A > Mesh > Cylinder).
  2. Press Tab to enter Edit Mode.
  3. Switch to Vertex Select mode.
  4. Select the top ring of vertices. You can do this by holding Alt and clicking on one of the vertical edges.
  5. Press S to scale, then type in a smaller number like 0.5 and press Enter.

You’ve now changed those vertices position, creating a tapered shape. You can do the same with the bottom ring, or scale the middle rings for more complex forms.

Practical Method 2: Moving Individual Vertices

For more organic changes, you’ll move vertices by hand.

  1. In Edit Mode (Vertex Select), right-click on a single vertex to select it.
  2. Press G to grab it and move your mouse. Click to place it.
  3. To select multiple vertices, hold Shift while right-clicking on them. You can also drag a box selection with your mouse cursor.
  4. Press G to move the whole group.

This method is perfect for creating bumps, dents, or asymettrical shapes on your cylinder. Don’t worry about making it perfect; you can always undo.

Using Proportional Editing for Smooth Changes

Proportional Editing is a powerful tool for changing vertices naturally. When you move a vertex, it affects other vertices nearby with a falloff.

  1. With your cylinder in Edit Mode, locate the Proportional Editing button in the top middle of the 3D viewport. It looks like a small circle. Toggle it on, or press O.
  2. Select a vertex on the side of your cylinder.
  3. Press G to move it. You’ll now see a white circle.
  4. Scroll your mouse wheel to increase or decrease the circle’s influence.
  5. Move the vertex and watch how others around it follow smoothly.

This is ideal for creating smooth bends or bulges in your cylinder without creating sharp edges.

Adding More Vertices with Subdivision

Sometimes, the default cylinder doesn’t have enough vertices for the detail you want. You need to add more.

  1. In Edit Mode, select all vertices (A).
  2. Right-click in the viewport and choose ‘Subdivide’ from the menu.
  3. Look at the operator panel in the bottom-left of the viewport (you may need to click the small arrow to expand it).
  4. Increase the ‘Number of Cuts’ to add more ring loops around the cylinder.

More vertices give you more control. You can now create more intricate shapes because you have more points to move and adjust.

Loop Cuts and Slide for Precision

The Loop Cut tool adds a ring of vertices around the cylinder at a specific location.

  1. In Edit Mode, press Ctrl + R. A purple loop will appear around your cylinder.
  2. Move your mouse to position the loop.
  3. Scroll the mouse wheel to add multiple, evenly spaced loops at once.
  4. Left-click to confirm. Before clicking, you can left-click and drag to slide the loop up or down.

This is the best way to add geometry exactly where you need it. For example, add a loop cut near the top of a cylinder before scaling that loop to create a lip for a vase.

Advanced Technique: Using Modifiers

Modifiers are non-destructive ways to change geometry. They affect the cylinder without permanently altering the base mesh until you apply them.

  • Simple Deform Modifier: Great for bending or twisting the entire cylinder. You can taper it here too.
  • Displace Modifier: Uses a texture to push vertices in and out, creating surface patterns.
  • Array Modifier: Duplicates the cylinder along an axis. Change the base cylinder’s vertices, and all duplicates update.

To use a modifier, go to the Modifier Properties tab (blue wrench icon) in the Properties panel. Click ‘Add Modifier’ and choose one. They offer powerful ways to change vertices procedurally.

Applying a Subdivision Surface Modifier

This modifier smooths your cylinder by adding virtual geometry. It makes low-poly cylinders look round and high-poly.

  1. Add a Subdivision Surface modifier to your cylinder.
  2. Set the Levels Viewport to 2. You’ll see the cylinder get smoother.
  3. Now, in Edit Mode, the original vertices are easier to manage. Moving one will have a smooth, broad effect on the final shape.
  4. This is called ‘box modeling’ and is a very common workflow.

Common Problems and Solutions

You might encounter a few issues when changing vertices. Here’s how to fix them.

  • Flat-looking cylinder top/bottom: You might have deleted the central vertex on the cap. Ensure the cap has a central vertex (the ‘NGon’) for a smooth shade.
  • Sharp, jagged changes: You’re likely moving vertices without Proportional Editing. Turn it on (O) for smoother deformations.
  • Can’t select a single vertex: You might be in Edge or Face Select mode. Check the selection mode buttons in the top-left.
  • Shape looks lumpy: This can happen if you have overlapping vertices. Select all in Edit Mode and press M > ‘Merge by Distance’ to clean them up.

Practice Project: From Cylinder to Vase

Let’s combine these techniques to make a simple vase.

  1. Add a cylinder with 32 vertices for a smooth look.
  2. Enter Edit Mode. Select the top ring of vertices and scale them slightly inward (S, 0.9).
  3. Add a loop cut (Ctrl + R) near the top and slide it upward. Scale this new loop slightly outward to form the vase’s rim.
  4. Add another loop cut in the middle of the vase. Select it and enable Proportional Editing (O).
  5. Scale this loop outward (S) with a large influence radius to create a gentle bulge.
  6. At the bottom, add a loop cut near the base and scale it inward to give the vase a foot.

You’ve now successfully changed a cylinder’s vertices into a new object. Experiment with different loop cut placements and scaling values.

FAQs About Editing Cylinders in Blender

How do I edit a cylinder in Blender?

You edit a cylinder by pressing Tab to enter Edit Mode. From there, you can select its vertices, edges, or faces and use tools like Grab, Scale, and Rotate to change its shape. Adding loop cuts or subdividing gives you more vertices to work with.

How do I reduce vertices on a cylinder?

In Edit Mode, select the rings of vertices you want to remove. You can use Alt+Click to select a full loop. Then press X and choose ‘Delete Vertices’. Be careful, as this can change the shape drammatically. Alternatively, use the Decimate modifier for a automatic reduction.

How do I reshape a cylinder?

Reshaping involves moving groups of vertices. Use loop cuts to add geometry where you need detail, then select and transform those vertices. Proportional Editing is key for creating smooth, organic reshapes like bends or curves in the cylinder’s body.

Why are my cylinder edits looking jagged?

This usually means you have insufficient geometry. A cylinder with only 8 sides will look jagged when scaled unevenly. Add more vertices via the initial Add Cylinder options, or use subdivision surface and loop cuts to increase geometry for smoother deformations.

Mastering how to change vertices of a cylinder opens up a huge range of modeling possibilities. The key is to start simple: practice moving, scaling, and rotating vertex groups. Then, incorporate loop cuts for control and Proportional Editing for smoothness.

Remember, most complex models begin with simple shapes like cylinders. By learning these fundamental skills, you’re building a strong foundation for all your future 3D modeling projects in Blender. Keep experimenting with different selections and tools to see what effects you can create.
