cheese slope dimensions

[Tommy Carstensen]

This is my first post. I hope I follow all guidelines.

I want to know the dimensions of a cheese slope tile. I have downloaded the 54200.dat parts file, but I'm not sure how to interpret it. Can anybody help me?

I am interested in knowing the exact length of the side with a length of approximately 8.5mm:

Thank you,
