Answer:
This can happen if you have a node that is very far away from the main structure. It is recommended that you set the view to "Isometric" and then this will zoom out on your model and give you an idea of where these stray elements are located.
You will need to delete these elements that are not attached to the structure or move them closer.
Note: Enlarged graphical issues can happen when importing a model from another format and the structure is extremely far away from the origin. The solution to this is to move the model as close as possible to the origin.
