Advanced Plot Equation

The Advanced Plot Equation add-on lets you graph explicit, parametric curves and full 3D surfaces directly in Blender.
- ✏️ Enter any math formula (y=f(x), x(t),y(t),z(t) or x(u,v),y(u,v),z(u,v))
- 📊 Adjustable domain & resolution (start/end, steps)
- 🔄 Instantly redraw with Undo support

• Explicit Curves
  Plot y = f(x) over any range with custom step count.
• Parametric Curves
  Define x(t), y(t), z(t) to draw 3D paths.
• Parametric Surfaces
  Create meshed surfaces via formulas x(u,v), y(u,v), z(u,v).
• Safe Eval
  Only approved math functions are allowed for security.
• Dynamic Redraw
  Change expressions or bounds and press Draw again.
• Undo-Friendly
  Each draw is an undo step for easy iteration.
