As of version 2025.d, the air distribution system can be designed by selecting the alignment point of the ducts and their connections.
Up until this version, CYPEHVAC only allowed the duct axis to be entered as a reference so that its dimensions and all the necessary connections took this reference to modify its size and position.
From now on, users can select as a reference not only the axis, but also any of the vertices of its section and even the centre of any of its faces.
