Instead you hear a Microsoft Windows sound. |

This can e.g. happen when you click on a BC, while you are in the Sync Views mode.
Unfortunately this is a limitation of Revit. You just need to wait untill the highlighting is done, typically some seconds. You can : |

| title | What is the difference between Hysopt Optimiser and Hysopt BIM Syncer? |
|---|
|
The best way to explain the difference between the Hysopt BIM Syncer and the Hysopt Optimiser, is to explain the common functionality and the specific differences they have. Common | BIM Syncer | Optimiser |
|---|
Both the Hysopt Optimiser as the Hysopt BIM Syncer share the functionality to: Rapidly model P&ID schemes: Calculations: | Specific BIM Syncer functionalities: BIM & Hysopt model generation Mapping Validation Synchronisation of system data Synchronisation of building data Synchronisation of calculation data from the Hysopt optimiser Export P&ID & reports to Revit sheets …
| Specific Optimiser functionalities: Optimise components Simulation Partial load analysis Sensitivity analysis Pareto Analysis …

The changes will be detected when you re-validate. Errors might occur when you removed some items. The mapping in the Hysopt BIM Syncer might think they still exist. |

| title | Are Pipe placeholders and analytical connections supported? |

|
Hysopt BIM Syncer can take Pipe placeholders and analytical connections into account. |
| Expand |
|---|
| title | How is a fitting (e.g. tee fitting) for which not all connectors are connected or a capped end handled? |
|---|
|
Connector of tee fitting is not connected (disconnects)In case of a disconnect, the BIM syncer will handle it as a fitting with two connectors, so it will not handle it as a Tee-point. | Info |
|---|
In this case, the pipe segments primary and secondary from the T-point, will all be handled as ONE branch |
 Cap open end of tee fittingPipe is connected to tee fitting which is capped with a pipe cap Tee fitting is connected with a pipe cap
BIM Syncer will handle that branch as a dead-end branch, and it will handle the fitting (from a hydraulic perspective) as a fitting with two connectors, so it will not handle it as a Tee-point. | Info |
|---|
In this case, the pipe segments primary and secondary from the T-point, will all be handled as ONE branch |
 A non-capped pipe is connectedIf a non-capped pipe is connected, then the BIM Syncer will handle it as a fitting with three connectors. It is assumed that this pipe is not fully modelled and needs additional pipe segments, fittings, and components. | Info |
|---|
In this case, the pipe segments connected to the T-point will be handled as three different branches, seperated by the fitting |

Solution:Work through the following troubleshooting steps: look into the log file and see if there is a message that helps you further. look into the Windows Event viewer and see if there is a message that helps you further. collect as much info as possible and contact your reseller.

Disable the Sync Views mode when replacing Base Circuits| title | In Sync Views mode, Revit sometimes intercepts the "CTRL-H" command. Instead of showing the replace Base Circuits dialog, Revit annotates the menubar. |
|---|
| If you enable the Sync Views mode, click on a Hysopt Base Circuit, and subsequently press CTRL-H to replace this Base Circuit, Revit sometimes intercepts the command to show annotations on the menubar. The Replace Base Circuit functionality of Hysopt is not loaded.
Image RemovedUnfortunately this is a Revit limitation that cannot be fixed.
However, there are some workarounds to avoid it :
don’t click too quickly on different hysopt Base Circuits
(give Revit the time to sync the view and highlight the Revit element before clicking on the next Base Circuit)
lower the higlight time in the settings page to 1 second
| Can Hysopt BIM Syncer work with a central model when using Local collaborate or BIM collaborate? |
|
Hysopt BIM syncer can work with a central model. There are two situations: Revit model is linked to a Hysopt model before central model creation Revit model is not linked to a Hysopt model before central model creation
every user with a local copy is able to overwrite the Hysopt model.  Image Added Image Added |
