Cartoon Animator only uses 2D. It does not use 3D characters or props.
The benefits of using 2D is that any photo or drawing can easily be made a character or prop inside Cartoon Animator.
So even if you convert your 2D image to 3D you will still need to convert it back into a 2D image to be able to use it in Cartoon Animator.
So the best way to resolve the issue is to try and find a photo or drawing of the prop you want to use at the right angle. So for example a chair that is visible at the angle you want so your character can be positioned so that it looks like it is sitting on the chair as shown below.
