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 model is created with “Base Circuit placeholders”
because not all components are ‘recognizable’(standardization issue) only if classification is available (ETIM, uniclass , omniclass , .CBNL,
because sometimes components are not completely drawn (e.g. floorheating , see next)
Production placeholder
Component placeholder
Regime changing placeholder
End unit placeholder
Revit 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.

Messages
Start Hysopt model generation
Unsuccessful Hysopt model generation
Warnings
HVAC related BIM elements were not processed during the generation
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
Errors
No end units found
Successful Hysopt model generation
all HVAC related BIM elements were processed during the generation
Generated model contains parallel branches, this is not fully supported yet in Hysopt
Replacing placeholders
For most of the calculations supported by the BIM Syncer we don’t necessarily need to replace these placeholders
Except for following two exceptions :
System check pump
Pipe calculations regime changing components (see following example)
Semantic validation (see further)
Header configurations (see further)
