Unit Conventions
Unit conventions
Revit_Toolkit follows the BHoM unit conventions. All Revit units are being converted to BHoM SI units with BH.Revit.Engine.Core.Convert.FromSI and BH.Revit.Engine.Core.Convert.ToSI methods. Please note that in order to account for the breaking changes in unit handling in Revit API, it is recommended to use the following to work with Revit units in BHoM to avoid applying preprocessor directives:
| Action | Revit 2020 and below | Revit 2021 and above |
|---|---|---|
| Get unit type of parameter Definition | BH.Revit.Engine.Core.Query.GetSpecTypeId |
Autodesk.Revit.DB.Definition.GetSpecTypeId |
| Get display unit type of Parameter | BH.Revit.Engine.Core.Query.GetUnitTypeId |
Autodesk.Revit.DB.Parameter.GetUnitTypeId |
| Get unit type by name | BH.Revit.Engine.Core.SpecTypeId |
Autodesk.Revit.DB.SpecTypeId |
| Get display unit type by name | BH.Revit.Engine.Core.UnitTypeId |
Autodesk.Revit.DB.UnitTypeId |
