Hysopt BIM Syncer can create a P&ID model (calculation model) from a Revit model. It uses a smart algorithm that first identifies the end units (heat emitters) in your system, such as radiators, fan coils, or floor heating. Then, it analyses how the system is connected with components and pipes, such as pumps, valves, or fittings. The algorithm stops when it reaches a production unit, such as a boiler, chiller, or heat pump. This way, Hysopt BIM Syncer can generate a complete and accurate P&ID model of your system.
To identify if a Revit component is an end unit, Hysopt BIM Syncer uses the classification of a Revit component. If it is not possible to identify if a Revit component is an end unit, than you should help the algorithm with adding assistance parameters.
Basecircuit placeholders
The generated Hysopt model is created with “Base Circuit placeholders”. (What are base circuits?)
A placeholder is a useful tool when we want to generate a Hysopt model in the Hysopt BIM Syncer without knowing the classification of the component or without fully drawing the components (eg. floor heating). A placeholder allows us to assign a generic type to the base circuit, such as a production, component, pump, regime changing and end units without specifying its type (eg. component → valve → on/off valve). This way, we can still model the P&ID of the system, even if we do not have a complete classification of the component. A placeholder can be replaced later by a specific component if needed.
Production placeholder
Production placeholders are used for replacing a production unit, such as a boiler, chiller, or heat pump
Component placeholder
Component placeholders are used for replacing components, such as three-way valves, strainers, or on/off valves
Pump placeholder
Pump placeholders are used for replacing pumps. If the classification of the Revit component of the Pump is not present. The Revit component will be generated as a component placeholder.
Regime changing placeholder
Regime changing placeholders are used at locations in the system where components or connections will affect the temperature regime in the system.
Component
Regime changing component placeholders are used for components, such as heat exchangers, heat interface units, low loss headers
Distribution unit
Regime changing distribution unit placeholders are used for bypasses and three-valve configurations. There is a difference in types:
Type 1 distribution unit with component on bypass
Type 2 distribution unit without component on bypass
Type 1 Type 2
End unit placeholder
End unit placeholders are used for replacing end units, such as radiators, floor heating, or fan coil units
Replacing placeholders
For most of the calculations and validations supported by the Hysopt BIM Syncer we do not necessarily need to replace the placeholders
Except for following exceptions :
System check (pump placeholders needs to be present or component placeholder should be replaced by a pump base circuit)
Compute design flows and select pipes (regime changing component placeholders must be replaced)
Semantic validation
Header configurations
Piping system
In the Hysopt BIM Syncer we know several applications :
heating
cooling
By default, the Hysopt BIM Syncer will take a look at the endunits, and based on the available info on that endunits, generate a model with the corresponding application. If no further information is available, it will generate by default a heating application.

Unprocessed mixing/dividing point in the system. Maybe you need to mark some components as endunit on these branches
We found a branch with an unknown location," this might indicate that the classification type of the pipe segments is not consistent in our BIM model
This point in the system has {number} pair of branches, this is not supported yet by the generator
