Computer-Aided Design (CAD) software is used to create 2D or 3D models and diagrams to visualize designs and spatial arrangements. In a technical theatre context, CAD is particularly useful for:
- Creating lighting (LX) plots and plans.
- Designing sound pit and band layouts for tight spaces.
- Calculating cable lengths for large rooms or outdoor events.
- Running LX pre-visualization ('pre-vis') software for programming cues in advance.
Note: CAD can have a steep learning curve and may be overkill for simple designs where a pencil diagram is more efficient.
