Please allow connections between Pipe and Duct tools

Hi,

I would like to request a feature to allow connections between Pipes and Ducts in the new MEP Modeler (AC28+).

In real-world scenarios, such as Sanitary Vent Stacks, we use Pipes (PVC/Cast Iron) to route the air, but they eventually connect to Roof Fans or Ventilators, which are often Duct-based objects.

Currently, it is impossible to connect a Pipe segment to a Duct terminal or Fan. Please introduce a "Pipe-to-Duct Transition" or allow a compatible connection between these two domains.

This is a critical workflow for plumbing design.
