One of the really nice features of Fusion 360 is the ability to place reference JPGs to the various planes so that you can get the model to scale and to look like the reference image. This would be such a great (and I would hope easy) function to add to TInkercad. I have been getting into videogame weapons, and although Fusion 360 might be better for some of the really complex models, it's still way out of my league. I've been able to do some really cool replicas in Tinkercad, but the ability to import reference images on the planes in Tinkercad would be outstanding.
