Learning to design a Faceted Dome (like a geodesic or architectural dome) in FreeCAD using a Python script is a key skill for tackling geometric complexity, architectural design, and fabrication.
Achieving Geometric Precision A faceted dome is defined by a rigorous network of precisely sized and positioned faces (usually triangles or hexagons). Manually calculating the coordinates and orientation of every single vertex and face for a large dome is virtually impossible and guarantees errors. Python scripting allows you to use iterative logic and trigonometric functions to define the entire structure flawlessly. The code becomes the single source of truth for the dome's complex geometry.
Full Parametric Control The term "Editable" is what makes scripting invaluable here. A scripted dome allows you to control its complexity and size instantly by changing just a few variables:
Subdivisions: Increase the number of faces (the "frequency") to make the dome smoother, or decrease it for a more geometric look.
Radius and Height: Instantly scale the entire structure up or down, or change its profile from a hemisphere to a shallower or taller dome.
This parametric flexibility is essential for architects and engineers who need to quickly test different design configurations before settling on the final dimensions.
Preparation for Fabrication Faceted domes are often built using flat panels (sheets of wood, metal, or plastic) cut and assembled on-site. Once your geometry is generated by the script, you can use additional Python code to:
Identify Unique Panels: Determine which facets are identical for minimizing cut lists.
Calculate Panel Angles: Get the exact dihedral angles between adjacent panels for manufacturing jigs.
Export Cut Sheets: Automate the creation of 2D drawings for CNC or laser cutting.
In short, scripting a faceted dome transforms a challenging manual modeling task into a precise, automated, and fabrication-ready engineering solution.
