Would it be "cheating" to use 3D models for 2D art?

Hello,

I mostly draw 2D art without any sort of 3D models as a base, though I sometimes use one to try and help myself practice. One of the main issues I've had is drawing objects, especially while dealing with perspective, and was wondering if it would be considered "cheating" or whatever if I were to use 3D models to help me out occasionally by tracing them (whether partially or fully), just for a little while as I try to get the hang of it. I'm also curious about whether or not it would make this be/feel/look less like "cheating" if I were to use my own 3D models, assuming I ever get into making them at all.

Would it be "cheating" to use 3D models for 2D art?

Please help.

I didn't find the right solution from the Internet.
