Is there a way to change the background color for RAM Elements to white instead of the normal blue color?
Regretfully no, this is not a user setting.
I routinely change the background color from dark blue to white and back to blue again. I do this so that I can make a screenshot of selected portions of my model with the white background to annotate my calculations. Microsoft Snip & Sketch makes it easy to paste it in a spreadsheet, Word document or pdf. However, I have to work with the blue background because the white background is hard on my eyes and I have to change it back to blue. Using the Output/Save 3D view is not a good option either. It can work, but it is rather clunky.
To change the background color, go to File/Settings/General Configuration/Display. You have 3 Color themes Dark (blue), Light (white) and Black.
If you only need to change this one time and forget it, then it is no problem. But for me, that is 6 clicks to change it and 6 clicks to change it back for each screenshot. I would like to suggest to the Bentley Ram Elements team, "Please put a Color Theme button in plain view to make it easy to toggle back and forth".
