Do not dimension them. Add a note to your drawing that states that the math data is the master. I am assuming you create dxf files for the laser cutting and your vendor is not re-drawing dxf files from the dimensioned drawings.
This concept is a minimum content drawing or reduced dimension drawing.
There is an ASME standard for Model Based Definition. A model based enterprise is also a requirement now for DoD work. http://model-based-enterprise.org/default.aspx
Reduced dimension drawings saves us tons of time in our engineering department and in our manufacturing areas.
