Update:1 After working with blender . I got the concept how to create. Just for motivating i am sharing a sample. Here i drawn simple sample outline . Lighting and more 3d parts not worked out in this image.however i want to convey that i got understanding of some important basic concept.
I tried almost all filters in inkscape. in that materials -> metallized paint also not giving the result like in illustrator. Any blur,gradient,shading and lighting guide will be more helpful for me. my present design in inkscape given below.
