By "2D isometric view" do you mean one of the 8 potential isometric views or do you seek to duplicate the specific random axonometric projection of the 2D flatshot geometry? Also, although you use the term "camera" should it be assumed that you are dealing with a parallel projection. Camera views may yield a perspective projection.
If a true isometric, just choose one of the predefined isometrics in the view command or you can rotate the model in 3D space. From a principal view, rotate the 3D model by + or - 45° about the vertical axis then + or - 35.2644° about the horizontal axis to yield an isometric orientation.
If you need to reproduce a random axonometric project it would help to know 3 points that lie on a plane that is parallel to the viewing plan or 2 points that lie on a line perpendicular to the viewing plane. If you don't have these points then you would need to know the x, y, z coordinates of points in the 3D model and their corresponding u, v coordinates in the 2D projection.
