How to get the height difference of these two screw hole?

Perhaps check Gerber Drill file under CAD Resources tab for product

There are several ways to determine the desired difference. One would be to read it from the GERBER data as recommended by @Tesla DeLorean. Another is to determine the difference from your screenshot, because all the values required for the calculation are given (typically, technical drawings do not specify each individual dimension, but use chain dimensions):

• left hole:
  • CN8.6: Y = 0
  • CN8.1: Y = 0 + 5*2.54 = 12.7
  • CN6.8: Y = 12.7 + 5.08 = 17.78
  • CN6.1: Y = 17.78 + 7*2.54 = 35.56
  • left hole: Y = 35.56 + 13.97 = 49.53mm
• right hole:
  • CN9.1: Y = 0
  • CN9.8: Y = 0 + 7*2.54 = 17.78
  • CN5.1: Y = 17.78 + 4.06 = 21.84
  • CN5.10: Y = 21.84 + 9*2.54 = 44.7mm

Difference = 49.53mm - 44.7mm = 4.83mm

Does it answer your question?
