Generic Bottom Hung Window with SECO N 24 25

This BIM object represents a generic bottom-hung window that automatically assigns the most suitable SECO N 24 25 chain actuator based on the window’s structural opening dimensions. As the window geometry is adjusted, the embedded logic selects the appropriate actuator model, stroke length, and performance characteristics to ensure compliance with operational and manufacturer criteria.

The object simplifies specification and coordination by enabling dynamic actuator selection, validating suitability for required opening forces, and automatically updating metadata such as actuator model, power requirements, and mounting constraints. This ensures accurate actuator specification throughout the design process and supports integration with ventilation and automated building systems.
