In the process of using C-V-P analysis, what does it mean to “break even”?

Break even is when revenues equal expenses. i.e. you only broke even and did not lose anything or make any profit.

A sample in the format for CVP:
10,000 Sales
- 7,000 Variable Costs
3000 Contribution Margin
-3000 Fixed Costs
-0- Profit (broke even)

And this format I'm using is something you'll also need to know.
