I want to display multiple viewports for a single model. However, when I try to assign my top-level ModelVisual3D element to an additional Viewport3D object, I get an error that says "Specified Visual is already a Child". What is the right way to do this Thanks for your time.

Like Visuals, Visual3Ds can only have one parent. Fortunately, Model3Ds can be shared. Share the root Model3D across multiple Visual3Ds.
