The following example shows you how to create a parametric 3D curve. Please read
Create a 3D parametric curve for detailed information about the command and its options.
Create a circle
The following example creates a circle in 3D space like this:
1. Click 3D Geometry and then, in the 3D Curve group, click More next to Spline 3D.
2. Click Parametric Curve Approximation in the Direct section. The Parametric Curve dialog box opens.
3. Click Part and select a part in the Structure Browser, or type a new part name.
4. Click X Function and type 10*cos(t).
5. Click Y Function and type 10*sin(t).
6. Click Z Function and type 0.
7. Click Start and type 0.0.
8. Click End and type 6.283185 (which is 2*pi).
9. Click to complete the operation.
You should have a circle with its center at the 0,0,0 coordinate.
