Sometimes I just feel a little strange, why do I feel that the draft is better than the final? Initial: N, Z Anyway here is my Finial in Rendered and Shaded mode: And the process: (It's so hard to choose one idea from those drafts.) (The second logo in the first row really caught my eye, prahaps I should choose this one as my finial?) And the part about how the logo look like in 3D model: (I forgot how to fit the "Hatch" surface onto the 3D model, so I just choose use "Polyline" to recreate the closed lines, turn the lins into a 3D model logo, move the 3D model logo to the right position, hen use "Boolean Split" to create a nice "surface," and finial, delete the original 3D model logo.)
