I tried even to extend the depth of the outer void so I am sure that it cuts everything beyond the exterior wall. The revit family contains two nested void families in a host window family that cuts through the necessary different walls inside the project (as in the original post explained). So what I think you have to do is add a void to those window families, one that cuts beyond both faces of the wall, so that Revit can display them properly.
I opened 190404 Facade example.rvt and I see those triangular issues with the windows already. It seems to me that the problem is not with the IFC, but in the original model. Draw floors, walls, curtain walls, roofs, stairs, railings, doors, windows, and ceilings Select, modify, copy, and group elements Use and assign object styles.
#REVIT DUPLICATE WINDOWS ON UPPER FLOOR ZIP#
The zip is splitted in 2 volumes (and I added 'zip' at the end, otherwise I couldn't upload it): the included IFC-models ending on IFC4 and IFC2x3 are the exports that I made with R2019.2.1 and the current solution of the IFC-exporter. On level 0 / 2 / 4 / 6 the cuts are not going through the 3rd wall. IFC2x3CV2.0: the cuts on level 3 & 5 don't have any artefacts (?), On level 3 & 5: the geometry (with the artefacts) is consistent with the geometry in R2019.2.1 IFC4RV1.2: the cuts through the 3 walls are going well, except on level 6: there the cut is not going through the 3rd wall. When I do an IFC-export from R2019.2.1 with the current solution (branch IFC4RV): (the original RVT & IFC are included in the attached zip) When I open the model in R2019.2.1 there seems to be artefacts at level 3 and 5, which were not present in 2019.2 (as the author confirmed to me). The original model is modelled in R2019.2 Issue: opening that cuts through multiple walls isn't cut everywhere.Īt first there seems to be a Revit 2019 issue (not the exporter).
