Specify the settings for the 3D view window on the ‘3D view’ tab of the settings dialogue box (Ctrl + e).

Click one of the colour fields to open a window in which you can select background colours for the 3D view window. A colour gradient is set by default. You can change this under ‘Colour gradient’ or by setting a check mark for ‘No gradient’.

Specify here whether you want the edges to be smoothed in the 3D view and how much you want the edges to be smoothed. If your front panels are elaborately designed, it is advisable to reduce the antialiasing factor in order to ensure shorter loading times.

You can choose between parallel and vanishing point perspective.
