The 3D view is cut when I try to zoom in to a large model. Is there any way to solve it?
This happens when there are 3D elements very far away from the main model. This is usually a origin reference point or line that came in from the model authoring software.
Remove that object and the problem is solved.
You can locate/remove the object by using the view cube to zoom to extents and box select around the model. You can also select the model and use inverse select, or you can find it from the 3D objects tree.
