Q - question

Parametric 3D curves in Fusion 360.

A - answer With a simple Fusion 360 plugin "Equation Driven Curve" (see Apps) you can generate parametric 3D curves defined by a mathematic expression (similar to Expression curves in Inventor or 2D Plot in AutoCAD).

After you install the plugin, the function "Equation Driven Curve" is available in the Create in the Sketch environment. Enter the curve prescription as parametric expressions for X,Y,Z depending on the theta parameter.

Examples of 3D knots taken from the expressions in Decorative knots (PDF):
