Hi mkdinesh2008,
My name is Pablo I'm an industrial designer with 12 years of experince in 3d modelling and rendering artist.
I can create a 3d model of your manual pipe tongs, given the proper images as referece.
Within my bid:
1) 3d CAD model manual pipe tongs (according to client specs.) in . STL and .DWG 2004 format.
2) 3d render or 3d object showing details
I will also include a 3d PDF for fast 3d exploration and fast feedback.
(don't worry you just need acrobat to see the model)
Looking forward to work with you Pablo.
