How to view the point of Max Distance and Min Distance specifically?

[[Sw...]]

My scanned file comprises of a planar sheet.

I have performed some of the actions mentioned below

1. Fitting plane using all the points
2. Flatness feature to get an idea about the maximum and minimum deviation

Now, since I have the values, how do I specifically view the part of my sheet having max distance and minimum distance?

Hi,

you can check the result with I-Inspect (hold CTRL when clicking) or via the menu to create min/max labels.

Another doubt that I have would be to calculate the rms value of the entire sheet. How do I calculate it, 

1. Does Zeiss inspect have an inbuilt feature? If so, how do I do it?
2. If not, can I export all the deviation values on a .csv file and calculate by myself? If so, how do I do it?

Edit:

1. I do see the option for standard deviation, which would be the rms from the mean points(the fitting plane), but what I want to understand is, is the surface rms of my scanned file should be calculated from the mean or the actual CAD file? If from the CAD file, how do I do it?

Hi,

you can calculate the root mean square of a surface comparison with a user defined check:

sqr(avg(pow(inspection.value,2),index='geometry'))

It is also possible to export deviation values as ASCII:

Hi,

As instructed I executed the same function. I am getting this error. Kindly guide me to solve

Hello,

this might not work for flatness checks and it looks like you are using the free version, which does not support user defined checks anyways.

Thank you for the response. Some more doubts to clarify and images below can give you an idea.

1. Scanned .stl file (grey) 
2. Reference CAD .stl file (teal)
3. The aim is to achieve the best alignment possible for the two files.
4. After referring to some of the videos available online, I am unable to pre align the two models in any orientation that I try to keep. 
5. How do I resolve this?
6. Kindly guide me, what would be the procedure to attain the best alignment?

Apologies for tagging you again but it would be great help if you can guide me and walk me through the right steps for the above problem that I mentioned.

Hi,

if the prealignment cannot be computed, please use a manual initial alignment like 3-2-1. or 3-point-alignment. I think the geometry has not enough features in every direction for the prealignment.

Referring to the doubt for calculating the RMS. I now am using a company account with a license, but now the issue persists with the error "The element does not support points". Kindly guide me on how can I fix this issue and proceed ahead?
Refer the image below.
