### FAQ

#### My maps are not loading in the site model

If maps are not loading in NavVis IVION, first verify that the SiteModel entity (Floor) includes the correct floor and point cloud for which maps need to be generated. If you made adjustments to the SiteModel, regenerate the maps. Note that the map generator works best in indoor environments without significant slopes — areas with slopes or ramps may result in only partial map generation. For detailed steps, see the troubleshooting procedure in this article.
