Polished drawings

I am trying to make the perspective views of my CREO parts to look like the attached snippets of drawings. The two elements I am missing (i.e. no idea how to render) is the possibility of drawing numbered lines from the view itself, and then come up with those thinner surface lines that give the illusion of mass and volume and depth.
I know how to put text labels in a drawing, but I am missing these two elements:
1) draw wobbly lines from the part to the exterior of the part, and
2) add surface thin lines.
I have attached the files with a model part and a drawing that I am trying to make look good, and some jpg snippets that show how the finished look should present itself.

P.S. I know CREO was not created for artistic drawings, and I know that the jpg drawings attached have a very polished look just because they were hand drawn by artists. I am not trying to replicate this polished look, not even in a proportion of 25% or less. All I want is to be able to number the elements in the perspective view, and put a little bit of life in these views of mine. Thank you!

P.P.S. I am willing to even go with a grainy texture that can be applied to the whole part and then made to look good in a black and white drawing (if such a thing even exists or it's possible).
