Adding 3d models from 3ds file to the scene is really easy with Ab3d.Reader3ds library. There are a lot of way in which that can be done - check the samples that come with the library to see which one suits your need.

If you are using Ab3d.Cameras and camera controllers (for example MouseCameraController) you will still be able to rotate the camera around.

Clicking on the 3d models from 3ds file is not as easy as it is on the UIElement3D because there are no direct event on the read 3d models.

But you can use the EventManager3D that comes with Ab3d.PowerToys - this really helps to add event to the 3d models - see the sample that come with Ab3d.PowerToys.
