In Output, I am not able to select structures or nodes. What is causing this?
In order to use the PLAXIS Output program to the fullest extent possible, the computer should support OpenGL 1.3 with 32-bit colours. When setting the colour quality to 16-bit colours, the user is not able to select items in the Output’s Model View, and it will not be possible to see the results for e.g. plates, walls and floors, interfaces, or to select nodes to be used for the curves program.
In order to solve it, please change the display's colour quality to 32-bit colours. To do so, go to Control Panel > Display > Settings > Colour quality. Change the value to 32-bit colours.
