3D moving problem

[Fr33d3l_]

 hello guys,

so I was in my 3D in AC25 file and I wanted to zoom to room (also with WADS buttons) and my view is little bit upfront and my every object (walls, slabs,etc) is okay but meanwhile while zooming closer, its starts to disappear (look photo) but its there. Can you help me please? Thanks

Is there any 3d element placed away from the project origin????

Go to the floorplan turn all layers on and zoom to fit to check what is happening.

Check if there is a 3d element far away from the project origin. In the 3d window turn all layers on and "zoom to fit". If the model is zoomed out (far away) maybe there is a 3d element placed far away from the project origin. Delete this element to check.
