And you recognized my inspiration for these buildings right away! :D

Haven't done any 3D printing so I can't help there.

You can try adding an RGB Matrix effect to the whole drawing or just selected sheets. See the attached screenshot (pre-defined RGB Matrix settings are located in the CC3+ program data folder under filters/settings/).

Are you always saving in the Dropbox? Can you change to a "normal" folder on your drive, e.g. under My Documents?

Try running CC3+ "as admin" by right-clicking the desktop shortcut and under Properties set it to "always run as administrator". Any change?

You can also use the Symbols > Scale Symbols in Map command from the menu to scale symbols centered around their point of origin, if you don't want to affect their default size.

Thanks for flagging this up., Chrome recently changed their policy and it now automatically blocks download links to a http address if you are coming from an https site. We already updated the links on the registration page, but not here on the public Annual page. I've done so now and the link should work on Chrome again now.
