Building on top of an image

[Milan Vančura]

You can make a textured quad out of it and put it in a .dat.

Or generate a sticker using my online script:

Then put that in the model and build over it in ortho mode.

Thanks a lot for this tip and for the generator page, Roland! I needed this several times but I did not know there is already a solution. Instead, I simulated ldraw modelling in inkscape - you may imagine the pain
