If your object is not part of the table below, proceed to rule 2. If you are unsure what this internal type is, this can be checked in the Revit API documentation (note: this requires some programming background knowledge to understand). The table below describes the internal type of Revit object, and how it is exported. It is not possible to override the rules described in this table in any way, and users are required to remodel the object using another method if they wish to get correct OpenBIM output. Revit has a series of hardcoded IFC export classes depending on the type of Revit object. The Revit IFC export code is far more nuanced, but it would take prohibitively long to describe all of the edge cases. Note that the rules described on this page are a simplification. Strap on your seat belts, because this is going to do your head in. If one rule cannot be satisfied, it moves on to the next rule until it finds a suitable IFC class. Revit follows a series of convoluted rules to determine what IFC class an object is exported as. 1.8 Rule 8: Check for particular hardcoded structural types.

1.7 Rule 7: Set blank predefined types to UNDEFINED.

1.6 Rule 6: Check IFC class mappings table.

1.5 Rule 5: Check if it is part of a furniture group.

1.4 Rule 4: Check for a manually overridden type parameter.

1.3 Rule 3: Check for a manually overridden instance parameter.

1.2 Rule 2: Check for a manually overridden parameter that exists in the family itself.

1.1 Rule 1: Hardcoded IFC export classes.

It may be useful to use the BlenderBIM Add-on IFC class search website to discover which IFC classes should be used. Therefore, if you make a spelling mistake, or accidentally type extra characters, the export will also be incorrect. Revit does not provide any interface or drop downs or lists that aid selection. which ones are not abstract), and all of the predefined types possible. To set IFC classes and predefined types in Revit, it requires intimate knowledge of all of the IFC class names, which ones can be used (i.e. Prior to reading this, it is important to first read the resources provided in Revit setup. It is possible to control which IFC classes map to which Revit objects when exporting and importing to some degree.
