I can convert your image, sketch to vector, Black and White 2-D Line Drawing
You can use the 2-D Line Drawing for Patent Applications or for manufacturing purpose as Prototype or for design purposes.
This hourly is for only one Illustration.
I use Illustrator CS6 for vector purposes. ( I don't use CAD).
Kindly Confirm the purpose of the Line Drawing:
I normally create Line Drawing with fills and strokes but sometime only Strokes are required like in embroidery and stencils.
Web, print etc.
NOTE:
Kindly consult me before purchasing any gig.
Because depending upon the complexity of the image/artwork you might need to buy multiple gigs for the single artwork.
