Overview:
A 3D mechanical drawing of a spinner helps visualize the object in three dimensions, showing all details for manufacturing or analysis.
Used commonly in engineering design and CAD practices.
Key Features:
Rotating body: Main cylindrical or conical structure
Axle/Shaft: Central support for rotation
Bearings: Reduce friction during spinning
Weights: Optional for balancing
Handle/Grip: For manual operation
Steps to Draw:
Draw the base in orthographic projection
Add the central shaft with correct diameter
Sketch the rotating body in 3D (isometric or perspective)
Include bearings and supports
Add annotations and dimensions
Design Considerations:
Material selection: Lightweight metals or plastics
Balance: Ensure symmetrical design for smooth rotation
Assembly: Consider tolerances for parts fitting
Safety: Round edges and smooth surfaces
Tips:
Use isometric projection for 3D clarity
Highlight moving parts separately
Maintain proper scaling for all components
