I am using ggRVT to export a few basic architectural elements in an IFC file and opening it in Revit (2026). Walls are mapped as walls but unfortunately slabs are not mapped as floors but as generic models.
Is there a proven way to have the slab be recognized as native Revit type? I tried several things (IFC version, Revit Open IFC settings, matching existing floortype).
Secondly, is there a way for the floor (or wall) to adopt an existing WallType from Revit?
Is this using the out of the box IFC import functionality? When you use the term Revit Open IFC I assume so.
When I started on IFC workflows into revit, I was hoping to generate a higher count of native elements, so I developed our third party IFC import plugin for revit which will succeed in more scenarios than out of the box does. IFC Import | Geometry Gym
Our import plugin will use existing families or symbols where the name is the same, so you can achieve that (You might have to modify the type name). For the slabs, it’s hard to provide advice without some sample IFC models. You can share it privately if you prefer not to post files publicly to the forum.
Indeed, i did not know about the plugin but i’ll give that a try. Thanks!
