Hello everyone. I am facing difficulty as whenever I import STL file and save it as new STL file, that new file does not have same coordinate with the previous one, whereas I want to keep the same position of new STL file like the old one had.

Herewith I also attached the example of my problem (including the STL file). There are 2 screws, the brighter one is the original one, while the darker one is from importing the brighter one to Solidworks and save it as a new STL file.

I would be very grateful to get some advice on how to keep the same coordinate between old and new STL. Thank you very much.
