How to Extrude in Cinema 4D

Understanding the Extrusion Tool in Cinema 4D: A Step-by-Step Guide

Introduction to Extrusion in Cinema 4D

Extrusion is a vital technique in 3D modeling that allows artists to add depth and volume to 2D shapes. This process takes a flat object and extends it outward or inward to form a three-dimensional structure. Whether you aim to create complex designs or simple geometric forms, mastering extrusion can significantly enhance your workflow in Cinema 4D.

Setting Up Your Workspace

Before diving into the extrusion process, ensure your workspace is optimized.

1. Open Cinema 4D: Launch the software and create a new project.
2. Adjust the Layout: Customize your interface based on your preference. Familiarize yourself with the Object, Attribute, and Toolbar areas, as they are crucial for modeling.

Creating a Base Shape

1. Select the Shape Tool: From the toolbar, choose the shape tool that best fits your needs (Rectangle, Circle, etc.).
2. Draw Your Shape: Click and drag in the viewport to create your desired 2D shape. You can adjust the properties of the shape, such as width and height, in the Attribute Manager.

Converting to a Polygon Object

To apply extrusion, you must first convert your 2D shape into a format that supports depth.

1. Select the Shape: Click on the shape you created in the Objects panel.
2. Conversion: Right-click on the shape and select “Current State to Object” from the context menu. This transformation turns your shape into a polygon object, enabling extrusion.

Applying the Extrude Nurbs

To add volume to your already defined shape:

1. Locate Extrude Nurbs: In the Object menu, find and select the Extrude Nurbs option.
2. Parent Your Shape: Drag your polygon object into the Extrude Nurbs in the Objects panel. This action makes the polygon the child of the Extrude Nurbs, allowing it to inherit the extrusion properties.

Configuring the Extrusion Settings

Now that your object is properly set up, configure the extrusion parameters to achieve the desired effect.

1. Select the Extrude Nurbs: Click on it to access the attributes in the Attribute Manager.
2. Modify the Movement: Adjust the “Movement” option to control how far the shape should be extruded. Positive values extend the object outward, while negative values bring it inward.
3. Tapering Options: For varied thickness, explore the Taper settings which allow you to create tapering effects, adding a more dynamic look to your extrusion.

Refining Your Model

After extrusion, it’s essential to refine your model for better detail and quality.

1. Select Polygon Mode: Switch to the Polygon mode in the selection menu to fine-tune the shape.
2. Add Subdivision Surface: If your model requires smoothness, apply a Subdivision Surface object. This will refine the edges and smooth out the polygonal facets.
3. Utilize the Knife Tool: For added detail, you can use the Knife tool to cut further into the geometry, allowing for more intricate designs.

Rendering Your Extruded Object

After finishing your model, the next step is rendering.

1. Set Camera View: Position your camera to achieve the best angle of your model.
2. Lighting: Add lights in your scene to enhance the visibility and depth of the extruded shape.
3. Render Settings: Adjust the render settings to your preferences, then hit the render button to visualize your work.

FAQ Section

What is the purpose of the Extrude Nurbs function in Cinema 4D?
Extrude Nurbs is used to convert 2D shapes into 3D models by extending their surface, allowing artists to create complex visual elements with depth and volume.

Can I undo changes made during the extrusion process?
Yes, Cinema 4D has an undo feature. You can reverse any changes by pressing Ctrl + Z (or Command + Z on a Mac) to revert to the previous step.

How can I further edit my extruded shape after applying the Extrude Nurbs?
To modify your extruded shape, you can either adjust the Extrude Nurbs settings or enter Polygon mode to directly manipulate the geometry for finer control and detail enhancements.
