S500 Quadcopter Drone Drawing
This page showcases the mechanical drawing of an S500 quadcopter drone, modeled using SolidEdge. The aim of this project was to sharpen my CAD skills through practice.
Initial Frame Drawing
The first stage involved creating a symmetrical base structure with cutouts to reduce material usage. The initial drone frame included triangular cutouts in the arms to reduce weight. However, I later learned that sharp corners can become stress concentration points, which may weaken the structure under load. I later added 1mm fillets in all sharp corners as seen in the mid-stage assembly.
Mid-Stage Assembly
The second stage involved assembling components on the frame, which helped reinforce my knowledge of 3D modeling tools like extrusion, offsetting, alignment, lofting, patterning, and reference planes.
Final Assembly
This stage represents the full assembly of the S500 quadcopter drone, integrating all major components including the structural frame, curved landing gear, battery compartment, and electronic modules. In this stage of drawing, I deepened my understanding of sweeping and cutting.
Propeller Modeling Attempt
As part of the final assembly, I attempted to model the propeller blades using the loft feature between guide curves and profiles. However, due to the complex curvature and twisting nature of real propeller geometries, I was unable to model them. Despite this, the process overall helped me better sharpen my skills and I look forward to learning how to model propelers in the near future.
