I did a demo of using Maya measure tools for my YouTube Channel. How to render Maya measure tools. I did a search online and notice this post here in HighEnd 3D, 2001!, (I use the rigs you have supplied for tutorials in animation).
Workflow is render with Maya Hardware Render 2.0 > Maya Hardware Render 2.0 TAB> Render Options, choose Wire from Render mode field. Scroll to Object Type Filter> choose all from list, (you can select what to render for wireframe output). Select all the objects for rendering in your outliner or drag select (highlighted they look brighter).
Be sure to change background color in the selected camera Top View>environment> color selector> middle gray for good contrast of curves and measure tools active in your scene.
Hope that helps.
