Automatic selection and placement of fittings to align with DW-144 in ductwork

I would like the software to recognise the perimeter loop duct arrangement and calculate the airflow through it. This solutions reduces resistance and provides enhanced airflow performance. This is specific to Small duct high velocity systems.

I would like to be able to export the duct references, sizes lengths in an excel spreadsheet

I would like to be able to create a schedule of the duct references and sizes

Allow fixed pressure drop through ductwork equipment such as attenuators, rather than just k values/ zeta values

Having a way to calculate the air throw across the room when using wall grilles, that would be a fantastic feature, currently, we’re working that out manually

Currently in H2X, there is no pressure drop rate (Pa/m) to show in the result, only pressure drop(Pa) for the whole duct length. We need to calculate them using duct sizer every time.

Please consider fixing mismatches between ductwork items listed in the automatically generated BOQ and the actual duct dimensions defined in the design model. Currently, the BOQ output reflects different duct sizes than those specified in the design, which leads to inconsistencies during quantity take-offs. Additionally, it would be highly beneficial to incorporate an optional feature to quantify ductwork not only by length and dimensions but also by total estimated weight (kg) of steel sheet. This would enable a more accurate estimation of fabrication costs, material handling logistics, and structural load assessments—particularly relevant in large-scale MEP projects.

MVHR air handling units come in many configurations. It would be helpful to have the ability to switch the Fresh Air, Exhaust Air, Supply Air & Return Air into any configuration required to meet specific MVHR orientations. For example, a specified unit can have Fresh Air & Return Air on one end of the air handler with Exhaust Air & Supply Air on the opposite end. See equipment specs attached.
