Hi, Was wondering if anybody have solved the issue of ceiling grid to IFC? At the moment we have modeled the ceiling as an IFC covering/(ceiling) with the slab tool. That basically is just a slab in IFC. Last time I used the ceiling grid tool that also has IFC data it did not export the grid. And you cannot set the thickness on the ceiling grid in VW. The grid is extremely important to placing installations from ventilation and electrical engineers, and making it look good. Checking
