Blender: How to Curve Half of a Cylinder

Creating interesting shapes in Blender often involves manipulating existing primitives. This tutorial focuses on a specific technique: curving only half of a cylinder. This is useful for creating various objects, from stylized furniture legs to organic shapes. We'll explore two primary methods: using the Simple Deform modifier and leveraging the power of curve objects.

Method 1: Using the Simple Deform Modifier

This method offers a quick and easy way to bend half a cylinder.

Step 1: Create and Prepare the Cylinder

1. Begin by adding a cylinder using Shift + A > Mesh > Cylinder.
2. In the properties panel (usually on the right), adjust the cylinder's Radius and Depth to your desired dimensions.
3. Go into Edit Mode (Tab).
4. Select half of the cylinder. You can do this efficiently using the Select > Select All by Trait > Normals Face option. Then delete the other half with the X key and choose Faces.

Step 2: Apply the Simple Deform Modifier

1. Go back to Object Mode (Tab).
2. In the Modifiers tab (wrench icon), add a Simple Deform modifier.
3. Set the Method to Bend.
4. Adjust the Angle value to control the degree of curvature. Experiment to achieve your desired bend. A value of 90 degrees will create a perfect quarter-circle, but you'll likely need a smaller angle.
5. The Deform Axis determines the axis around which the bending occurs. Experiment with X, Y, and Z to achieve the desired orientation.

Step 3: Fine-Tuning and Refinement

You can further refine the shape by adjusting the cylinder's dimensions before applying the modifier or by using other modifiers like Subdivision Surface to smooth out the curve.

Method 2: Using Curve Objects

This method provides more control and allows for more complex curves.

Step 1: Create the Curve and Cylinder

1. Add a Bezier Curve using Shift + A > Curve > Bezier.
2. Manipulate the curve's control points to create the desired shape. For a simple half-circle curve, you only need two points.
3. Add a cylinder as in Method 1, but don't delete half of it this time.

Step 2: Apply the Curve Modifier

1. Select the cylinder.
2. Add a Curve Modifier.
3. In the modifier settings, select the Bezier curve as the Object.
4. Experiment with the Axis settings to correctly align the cylinder's deformation with the curve.

Step 3: Delete the Unwanted Half

Now, switch to Edit Mode and delete the unwanted half of the cylinder.

Choosing the Right Method

The Simple Deform modifier is ideal for quick, straightforward bends. The Curve modifier offers superior control and flexibility for more complex curves and organic shapes. Choose the method best suited to your specific needs and desired level of control.
