You can import images using the Image tool or by dragging and dropping them from Windows® Explorer. You can import images into 2D views only.
To add an image to a view
The imported image displays in the drawing area and moves with the cursor. The image displays symbolically, with 2 crossing lines indicating the extents of the image.
Alternatively, you may drag an image from your local drive into a model view.
By default, images are imported behind the model and annotation symbols; however, you can change the display order.
