Lets say you made a rounded surface and you want a picture (bmp,jpeg or so on) what ever you can import into a sketch. to be on that surface .
I know you can do it with ease on inventor its a basic 4 clicks or so.
I've tried to create a new plane on the surface and project it towards the surface but solidworks doesn't acknowledge the picture as n sketch.
first use split line to make face and then use appearance >> face and then select that image file. You will be asked to save the p2m file. Save the file and the appearance will be applied.
Found a way to add a picture to a surface.
It's called a decal . Right fly out plane under appearances,scenes and so on.
