thanks it is helpful
Hello. First i hope you will excuse my poor english.
I did something like that some years ago (please, see renderings attached).
I don't remember exactly what software i used for the modelling, but it was with 3ds max that i made the renderings. This project was a sculpture that was never carried out. I don't remember much details about it, i only kept this renderings with me, and by the way, i'm not the sculptor, i made only the computer model and the renderings. The model is scaled 1:10 and the drawing sheet is DIN A3 scaled 1:1, a simple plane with planar mapping.
Sorry, i don't know Keyshot software. If it is useful for you i can give some more information. You can try also looking for tutorials about UV mapping and texture (or bitmap) wrapping. Ah, with regard to the first image you submit, i don't know anyone who draws the both sides of a sheet :)
