I'm having trouble with one of my models in BIMx; I set up the 3d view and save the hypermodel. In the preview, the views match what I defined in ArchiCAD 18. I select the picture but then can't navigate because the viewpoint drops below grade. In the interior viewpoint it starts outside the window and as I try to navigate the camera keeps falling lower and lower until I am again below grade and unable to jump onto the site. This is not happening with my other projects. Any suggestions?
