 ====== Creating a Parametric Geodesic Dome in Fusion 360 ======
-I tried to locate a simple and clear method to created a 3D dome morel in fusion 360 without realising how complicated the topic can seem if not understood from basic concepts. This document captures my discovery and with the constantly evolving internet where things lately seems to disappear, I document them here more so for my own reference, but with the hope that it can be useful for my fellow tinkerers too.

-A geodesic dome is typically derived from an icosahedron—a polyhedron with 20 equilateral triangular faces. The process of creating a dome involves subdividing each triangular face into smaller triangles (increasing the "frequency") and projecting the new vertices onto a circumscribed sphere. The frequency (notated as 2V, 3V, etc.) determines the number of subdivisions per edge and thus the smoothness and complexity of the dome.

   * **2V Dome**: Each edge of the icosahedron is divided into two segments, resulting in a relatively simple structure.
   * **3V Dome**: Each edge is divided into three segments, producing a denser, more spherical dome.
-  * **Higher Frequencies**: 4V, 5V, and beyond yield even smoother domes but increase modeling and fabrication complexity.

 The choice of frequency impacts not only the appearance but also the number of unique strut lengths and the ease of assembly. For most Fusion 360 users, 2V and 3V domes strike a practical balance between buildability and aesthetics.

 Before modeling, it's crucial to select a workflow that matches your goals for parametric control, efficiency, and downstream use (e.g., fabrication, visualization). The table below compares the main approaches:
