# After moving the geometric model, it becomes invisible from certain viewpoints, and at the same time, it cannot be picked.

After relocating the geometric model within the scene, an issue has surfaced where the model is not rendered and thus appears invisible when viewed from specific angles. Concurrently, attempts to interact with the model using picking functionalities, such as those provided by `vtkCellPicker` , fail to register any hits, indicating that the model is not only visually obscured but also non-interactable in these orientations.  
The picture below shows what a cube looks like after being moved.

ResetCameraClippingRange() has been used in the code.  
what kinds of problems can create such mistakes?
