Need to add more vertices on a part any help is greatly appreaciated.
If you want some help, you need to provide more detail. Specifically, add vertices to what? Provide a sample part, a sketch, anything to show what you're trying to do.
"...any help is greatly appreaciated."
I agree with Walter. I'd like to help, but without more information I don't know where to start.
Add more surfaces/faces with edges.....make sure that the edges have end points.
Seriously though, read your question back to you and see if you would be able to piece together what you would want if you hadn't seen your project....
In the sketch use the Split Entities Tool
Retrieving data ...
