Duct fittings constitute far more than just their 3D geometry. The parameters that define them also drive the generation of the 2D geometry that is used in manufacturing workflows. Over the years, inconsistencies between how the same inputs result in different outputs on different fittings has made it difficult for users and our development team to maintain. Additionally, anomalies in the output requires manual intervention in the manufacturing process to ensure fittings are manufactured correctly, and donāt result in waste. Our team is methodically addressing logged issues, improving code quality, and consistency, as we address issues that have been logged by users.
