Answer 1

I think the ViewPort3D will end up in the upper left corner of the Canvas with a Width and Height of 0 since Canvas never stretches its Children. Try to add Canvas.Left and Canvas.Top at the positioning of your choise and then add Width and Height for your Viewport3D. If you want your Viewport3D to always fill the available space then Canvas is the wrong way to go.
