Viewportaspect Ratio

Hello all,
is there anyway to setup the viewport aspect ratio to match the rendering setting? as 3ds MAx will show it when safe mode is on.attacheed is an immage illustrating my query.

thank you

Hi MNT- Try using the Safe Frame in DocumentProperties > Rendering > Safe Frame page- that will draw the rendering aspect ratio in the viewport - does that help?

Hi Pascal,
thank you for the reply. I have already tried to use the safe frame. unfortunately it does not fx it for me. the attached images illustrate how the viewports are displayed in Rhino and 3D’s MAx.
any tips?

Thank you
