How can I make the decoration to take the shape of any object I'm trying to make a design of decoration to be like the shape of " sphere, car, body ... etc "  for example I convert an image of decoration to be SVG then I make it like sphere shape .



as I used "simple deform" modifier to make it, but I can't use same modifier to make the decoration like the "heart, car, building, face ... etc ", for example can I replace the wires in the below heart with shown decoration in the beginning ? or make the decoration like shape of the car "if I have a car shape" ... then I can print it using 3D printer .
   

I hope my idea is clear for you .
You can achieve this effect with the Shrinkwrap modifier as long as the pattern you are trying to apply is a mesh. For this to work best you should create a volume of your pattern, preferably spherical, then apply the shrinkwrap modifier with the "project" setting.

I would suggest keeping the pattern flat, then adding the thickness after it has shrinkwrapped around the object (possibly with the solidify modifier).

An alternative is also the Cast modifier, however this works only on geometric objects like spheres or tubes.
