a proper way to align a deformed part

[Mranaskw]

hello friends

i received a housing that i suspected to be a bit deformed (bent but the features i want to measure are not affected) , i want to measure a couple elements , the thing is , using 3-2-1 with a fixture nor an iterative will be unreliable because it will clearly be offset to the cad , what should i do ?

make your alignment structure as localized as possible to the features you want to measure.
