There is an option to create a Conceptual Mass model in Revit from the outline of your detailed project.
When to use this option?
- Your project has multiple modelling issues (gaps between elements, missing thermal properties etc) which would take time to resolve
- Model is slow to process (large file file/complex/with many elements)
- Model is giving multiple warnings in Revit which will take time to resolve (under Manage Tab – Warnings)
- Use the Project Enclosure as an outline for creating a conceptual mass (worksets may be used to separate and control visibility of element categories such as ‘Enclosure’, ‘Mass’ etc)
- Create a simple Conceptual Mass within the envelope model using the detailed elements (curves on a project may be faceted).
- Create Floors level by level to ensure best control over separate Surfaces
- Create Mass Floors from Levels / Check Energy Settings
- Analyse this mass object with FenestraPro
Note: Creating an open plan conceptual model may not provide the accuracy you require at a more advanced stage. In this case, you may need to model the mass room by room which will more closely represent the detailed model.
Note: this video refers to an older version but the process is the same. Tutorial videos are currently being updated.
