title: Custom routes/paths/roads on Google Maps
body: <p>I need to be able to, using either V2 OR V3 (preferably 3), create paths which ignore buildings in a sense.</p>
  <p>I was trying to create even a kml file to draw out all of the paths myself, and then find some way to turn them on/off as needed.</p>
  <p>For example.  The user wants to go from point A to point B.  Between these points is a number of buildings.  The user physically CAN walk through these buildings(it's a campus).  I want to show them that on the map.</p>
  <p>This way you don't have to do a loop-de-loop around, say, a parking lot, just to get to the other end of it.</p>
  <p>If there is ANY way AT ALL to do this, I'd love to know.</p>
  <p>An example of what I require can be found here: <a href="http://www.uottawa.ca/maps/" rel="nofollow noreferrer">http://www.uottawa.ca/maps/</a></p>
  <p>It's all pre-determined paths based on the two inputs from the user into the dropdown menu.  I can plainly see this.  But I have no clue if a) this can be done in v3, and b) how on earth they did it themselves.</p>
  <p>Assistance required, and greatly appreciated!</p>
