So in the 3shape ortho appliance designer I have an export button on the top right above my viewer sliders and all and its always been there for me to export the ortho models. On my other computers the button is still there but on one of my computers its gone. I must have hit something to make it disappear but I don't know what. I am for now just using my other computers but I was just wondering. I tried googling it but that was no help at all.
