Happy to help Jack Sparrow
It is not every machine and the inaccuracy might be slight, but if it is something to consider. Also, I forgot to mention it is good to make the scale that will be checked in both the X and Y dimensions. A 5 or 6 inch is a good example as my calipers go to six inches.
Of course if the plan is one from past centuries there is also the potential that the original drawing has changed dimensions in one or both directions Luckily they usually have a measuring rule of their own at least in the X direction that can be checked first and sometimes adjustments can be made
