I'm translating for a company that creates specialized 3D software. In a lot of the brochures, there are bullet points for things like '3D road design.' or '3D visibility.' To my eye, the words 'road' and 'visibility' should be capitalized in these contexts.
To be clear, I'm asking about the cases in which 3D begins a sentence, and whether I should capitalize the word that comes after it.
Am I right? Is this basically on a how-you-like-it basis?
Additional question (really just curiosity): when I search for questions like this, is 3D an abbreviation or an acronym? I feel like it would technically be an abbreviation of an acronym?
