STEP import part modification problem

I imported a part in STEP format and I cannot modify, if I reduce or increase a value, it returns to its initial value and shapr says “operation failed because the resulting body wouldn’t valid”

Can you help me solve this problem?


Hello! There can be many reasons, can you please upload the file and a screen recording of the workflow that ends up in the error message? They would help a lot.

Yes, of course, as this procedure is done, I have never done it
