Understanding Curve node primitives

Curve node primitives are the basic curve shapes that you can use in the Geometry Node editor. These include Arc, Bezier Segment, Curve Circle, Curve Line, Curve Spiral, and more.

Where can you find Curve node primitives?

Just like the Mesh node primitives, the Curve node primitives can be found in the Add menu (see Figure 4.1), under the Curve entry, in the Primitives sub-menu. Once you hover your mouse over this entry, the menu shown in Figure 4.14 should pop up:

Figure 4.14: Curve Primitives menu

Each entry in this menu is a Curve node primitive. We will explain the commonly used ones in this heading, so without further ado, let’s get right into the Curve node primitives.

Curve Line node primitive

Using the Curve Line node, we can define a straight path. This will be useful when you want to align objects along a straight line or when you want to create a pole. This can be done by giving the curve thickness...
