Is there a way to get new dimensions if the user pinch zooms or shrinks the model?

I thought I can get new dimensions via .getDimensions() but obviously that won't work, because glb themselves aren't get big or small.
I want to have a button that, when clicked, will restore the image to the original size.

Dimensions are mostly useful in AR, as GLBs are in real world units of meters. For plain 3D, perhaps you mean reset the zoom? You can use mv.zoom(-100); https://modelviewer.dev/docs/index.html#entrydocs-stagingandcameras-methods-zoom to zoom all the way back to the stops (initial).

Okay, thanks!
A follow up question, can we get the data about how much the user zoomed in or out the painting?

Sure, try mv.getCameraOrbit().radius.
