Known Limitations

Model Limitations

The current version of Tandm has the following limitations with respect to models:

• If there are multiple ceilings, Tandm will select the lowest ceiling relative to the floor level.
• If a room in Revit cannot be created due to geometry issues with the model, then Tandm will not be able to recognize the room also and hence will not be able to place fire sprinklers.
• Obstructions must be detailed in 3D to automatically coordinate with these obstructions.
• Rooms with walls which are not 90° to the floor.
• Sloped Ceilings.
• Floating and cloud ceiling, and irregular shaped ceiling types.
• Floors that span across multiple Revit® levels.
• Basements will require the Room Splitting tool to be utilised so that less complex rooms are seen by Tandm.

Some complex models with odd room shapes that have multiple strange angles, and obtuse/acute angled spaces may have some inefficient layouts that may require some human adjustment to confirm compliance with relevant code or standard requirements.

Software Limitations

• Concealed Space sprinklers
• Tandm does not support IFC and DWG file formats.
• High Hazard Classification designs.
• Where Model Limitations exist (per above) this may cause sprinklers not to place.

Revit Third Part Add Ons Limitations

Users may occasionally encounter a white screen when first running Revit if certain third-party add-ons are installed.

Fig 10.3.1. White Screen on Initial Launch in Revit.

Explanation:
This issue stems from interactions with third-party add-ons within the Revit® ecosystem. The Revit® environment allows for extensive customisation, which can lead to unexpected behaviours when multiple third-party add-ons are used simultaneously.

While Tandm is committed to delivering reliable and high-quality solutions, we have no control over the development practices or software quality of external add-ons. As such, this limitation may occur in environments where conflicting or poorly optimised third-party products are present.

Workaround:
If you encounter this white screen:

1. Simply close the pop-up window.
2. Select the desired action from the Tandm toolbar.
3. The software will then run as expected.

Note: This limitation does not affect the core functionality of Tandm or its ability to perform as intended.
