Maya can be very accurate, theres a thread ove ron CG talk about that.

What you can do is create a curve with the desired points then go into the Attribute editor and edit the positions from there (flip open componants, with a CV's selected to get the correct XYZ coords.

You can probably do it faster in the script editor? by typing somethin like

curve -d 2 -p -1.33165 0 -8.186393 -p -4.317575 0 -0.22678 -p 5.271032 0 5.328555 -p 5.524819 0 12.002574 -p -0.0973986 0 10.204746 ;

where the numbers after the -p corrispond to the X Y and Z positions (where the -d is the degree flag and the -p is the cv position flag.)
