Max-Min points on scan

usrpcdmis
Hi,
how can i find the Max and Min points on scan along X or Y or Z ?
I need these values based on the actual reference sistem
Thanks

    When you dimension out the scan (profile?), set the "textual" mode to yes/on whatever name it is. That will give you max and min values.

    Thanks but i need some suggestions how create a procedure to find these values automatically.
  • Here's a sample of how I have extracted the High Point from a scan. I've included comments in the sample

    Hope this Helps Slight smile

    This will give you the MAX and MIN deviation of a scan when using the profile of a surface button. If you only want the MAX part you can delete the MIN.
  • Under Parameter Setting
    You Can Turn On Maxmin On The Dimension Output Format.\
    And It Will Display Max Min

    Good answer. Nobody wants to do anything easy these days. I should have thought of that.
