hi dear all , I would like to confirm the accuracy of my evaluation through sharing with you some of the steps I used for the measurement of accuracy between the virtual planning model and the actual postoperative model, I need your valuable opinion in this regard

the first step after I did the registration between the preoperative planning and postoperative

After the registration, with the help of pick’n Point I choose the reference model, which is a postoperative model
I made a point on the reference model as shown below at the area of interest to measure the distance between the same points between the two models, and later I chose the propagate the nonmesh model

then through Model to Model Distance the source model is the postoperative Model and the target model is the preoperative model and the calculation was done
4.the fourth and last step was to get the measured value through Mesh Statistics. I chose the absolute value and X AXIS, Y, AND Z AXIS
my question is this step are accurate for measuring the distance between 2 models ?
