The Aether Table required a groove that spiraled inward, a perfect channel for a hidden LED strip. He needed to tell the machine exactly where to wake up.
In the field of CAD and computer-aided design, designers and engineers often rely on programming languages, such as Visual Basic (VB) or Python, to create and manipulate geometric objects, including Bezier curves. One such programming language is AutoLISP, specifically designed for Autodesk AutoCAD. CIX, short for "Command Interpreter for X," is a programming language built on top of AutoLISP, used to create custom commands and automate repetitive tasks. biesse cix macro start_point line_ep endpath
Bezier curves are a fundamental concept in computer graphics and CAD software. Developed by Pierre Bezier, they are a type of parametric curve used to create smooth, flowing lines and shapes. In CAD software, Bezier curves can be used to design and model a wide range of objects, from simple shapes to complex surfaces. The Aether Table required a groove that spiraled
In this article, we explored the concept of Bezier curves, specifically the "Bissé" method, and showed how to implement it using CIX macro. The "Bissé" method uses a modified set of control points to create smooth curves with a specific "start_point" and "end_point". We also showed how to use the Bissé method in CAD software, specifically Autodesk AutoCAD, by loading the CIX macro into the drawing environment. Developed by Pierre Bezier, they are a type

The Bissé method uses a formula to calculate the position of a new point on the curve, given the parameter value (t) and the control points. The formula takes the form of a weighted sum of the control points, where the weights are determined by the parameter value (t).
