Modeling With Polygons and Primitives

In this lesson, we explore modeling with polygons and primitives in Cinema 4D — the foundation for creating both simple and complex 3D objects.

We start with basic primitive objects like the Tube and Cube, adjusting their size, height, and segment counts to set up clean geometry for modeling. You’ll learn how to use viewport display modes and handles to interactively manipulate primitives, and how enabling caps and fillets affects the final shape.

Next, we convert primitives into editable polygon meshes to unlock full control over their geometry. We cover the four main component modes:

• Model (Object) Mode – manipulate the entire object

• Polygon Mode – edit individual faces

• Edge Mode – adjust edges for shape and flow

• Point Mode – move vertices to fine-tune geometry

Using practical examples, we model a simple shelf and a low-poly pencil. Key tools and techniques demonstrated include:

• Inset Tool – offset faces inward for depth or detail

• Extrude Tool – create new geometry from selected polygons

• Bevel Tool – add subtle edge rounding to catch light and improve realism

• Loop / Path Cut Tool – add edge loops for sharper corners or better subdivision control

We also cover important workflow tips for polygon modeling:

• Use rectangular and brush selection tools for precise polygon, edge, and point selection

• Store polygon selection tags to quickly reselect faces later

• Control edge sharpness when using subdivision surfaces

• Work in wireframe and shaded view modes to better understand your geometry

• Optimize low-poly meshes before adding subdivisions for smooth results

Finally, we demonstrate applying multiple materials efficiently, including creating selection tags for specific polygon groups, and show how subdivision surfaces can transform low-resolution models into smooth, high-quality shapes without losing control over edge definition.
