Answer:

If you happen to delete your 3d view you can easily create a new one.

• First, navigate to the View tab > New view and, while holding Shift, click on Basic view.

You will now see two dialog boxes: View Properties and Create Basic View.

• On the View Properties dialog box, Load the 3D View presets/ properties and hit Apply. 

• On the Create Basic View dialog, you must place the coordinates for your floor level: If you modeled at the default Coordinate 0 (zero) simply click Create. Otherwise, enter the floor level (example 100') and click create.

Now the new 3D view is created.
