Drawing Dimension Question

[OhioAviator]

Hello All,

I'm not sure this is the right forum to ask this question, and if not, my apologies.

I have an outline General Arrangement drawing of a large electric motor that is manufactured in South Africa. I do not know how to properly interpret the shaft dimensions. The shaft diameter is noted on the drawing like this....
"225,046-0,029"

The coupling bore is noted on the drawing like this...
"224,967+0,046"

Other than knowing that all dims are in millimeters, can someone clue me in on how to read these dimensions?

Thanks,

it seems logic that shaft nominal dimension is 225,046 (note that in europe number 1.005,025 is 1,005.025 in USA)with a negative tolerance of 0,029 mm (0.029 mm in USA)and bore has a positive tolerance of 0,046 mm. Therefore, minimun space with less desirable tolerance is 0,004 mm
