Bring your model into BobCad. Go to BobArt and choose emboss from surface from the emboss model item, you'll have to set the stock properties for the surface here. Choose the surface structure you want from your model.
Now choose Emboss texture-From image. This will lay your image as a texture for your surface.
If this does not give enough detail for you, let me know and I can try to put some pics together to illustrate.
