I know that in SB scale 1 click is 15 cm (2 clicks are one foot), and in FD scale 22 pixels are 1 meter. But how can I convert SB and FD scales to the «normal» modelist scales (1:48 or 1:72)? Because I don't know the actual pixel length. Thanks a lot (with my appologies if the answer is obvious, or is explained in another topic). Cheers.
I'm not super familiar with how this works but Photoshop images are based on a "resolution" which is usually set in pixels per inch (when printed). This is normally 72 pixels per inch, and given this I assume you could do some math and end up with a basic method to display a printed-out drawing in the standard modeling scales.
Technical drawings that exist on a computer screen and plans that are printed out are two completely different animals, though, so I wouldn't even bother if I were you. Shipbucket is not meant to be viewed when printed out - it is first and foremost a pixel raster drawing format designed to be viewed on a computer or even (God help us) a phone or tablet screen.
