The model for the heating system can be built using MEP objects with connectors of the type Supply Hydronic or Return Hydronic.
The "underfloor heating" function allows you to automatically trace the pair of pipes. The element resulting from the generation is to be considered as a terminal of the plant and therefore to be connected to the distribution.
First determine a closed polygon within which to calculate the serpentine.
Then define an entry point for the pipes and then indicate the diameter, elevation and distance between the pipes.
You can add TAGs and Schedules to extract information about quantities.
