Hello,

I want to draw a race course with a single line and be able to place movieclips on it to represent cars. Is there a way to take a line and figure out its total length so you can determine where its midpoint is? I want to be able to pull from a data source and say "car A should be 18% of the way through the course, and car B should be 32% of the way to the end.

Any help would be lovely.

Thanks,  
Jon
