Field Elements Drawings Errors

In CAD drawing 2015_Game_Specific.pdf there is error with angle on Platform Side Ramp page 61. It is marked 46.1 but it needs to be less than 45 degrees e.g. 43.9.

Is anyone aware of other errors or is there a complementary way to verify dimensions when making practice elements?

We decided to build scoring platform first, then a chute and a lastly a step element. We completed the platform so far.

I wonder if anyone has found other discrepancies in the CAD files to be aware of when making other elements.

Also if someone has already made a simplified chute it would be great to receive a picture of the design.
