Introduction
Designing louvre doors manually in CAD is repetitive, time-consuming, and prone to errors, especially when handling multiple size variations.
To address this, we developed a Louvre Door Automation Tool using C# with Autodesk Inventor API. This tool allows users to generate complete 3D louvre door assemblies instantly by entering basic parameters such as height, width, and blade gap.

Parametric Design Approach
The system is built on parametric modelling, where the entire geometry is driven by user inputs.
Based on the entered dimensions, the tool automatically calculates blade count, spacing, and
proportions, ensuring consistency and enabling instant regeneration for new values.

Automated Assembly Creation
All components—including panels and blades—are automatically generated and positioned using predefined logic.
This eliminates manual assembly work and ensures accurate, repeatable results every time.

Smart Blade Positioning
A built-in algorithm determines the optimal number of blades and distributes them evenly across the frame.
This removes manual calculations and guarantees uniform spacing and alignment.

User Interface & Visualization
A simple WPF-based interface allows users to input dimensions and generate the model with a single click.
The final assembly is automatically fitted into view, providing clear and immediate visualization.

Conclusion
This automation tool significantly reduces design time, improves accuracy, and simplifies the creation of louvre door assemblies.
By combining parametric design with CAD automation, it transforms a repetitive task into a fast, reliable, and scalable process.
