Mid-Ordinate Distance

Mid-Ordinate Distance sets the amount of tessellation when a contour or breakline is added to a surface. I looked up the word Tessellate at dictionary.com and it didn't help me figure out why they used the word tessellate instead of something more intuitive in help. If you want more information Lou explains it pretty well on her blog which makes this just a reminder to myself for a good explanation of what it means.
