Project the 2d elevation of a pattern on a cylinder.

[Anonymous]

 This one is the reverse of what most people want (impart 2d pattern onto curved surface. i want to build a curved surface texture and then somehow project that 3d view onto a flat surface and keep some of the depth of pattern to impart a 3d look. A picture might help get the idea across? In the attached is the side of a cake with a pattern affixed to the side. All in proportion and easily created in f360. Let's say the dark icing is say 5mm thick and the cake as viewed in the photo is a flat surface. Project and extrude the flat image of the curved pattern as you see it in the picture onto a flat surface after modelling it as a pattern on a cylinder.

What view do you want on the flat surface, isometric, perspective, etc.? 

1. Define a plane based on the view desired.
2. Create a sketch on the plane.
3. Project the geometry onto the sketch.
4. Create a cylinder with it's axis parallel to the flat surface (not necessarily the sketch previously created).  Make the cylinder's circumference touch the deepest desired depth below the flat surface and the two outer edges of the flat surface.
5. Extrude the projected geometry using the To Object option with the cylinder as the object.

OK, I think I understand your process. It's a bas relief kindoff? I would
project a side elevation onto a plane. Instead of the original cake being
say 300mm dia you extrude to an arc from the plane. The arc would be 0mm at
the left & right edges and say 10mm chord in the centre (plus a thickness
for whatever material I want to build it with?) That's jolted my mind
passed the road block. Thankyou, I'll have a play around and get back to
you.
