Re-measure a feature according to a condition

[[Ri...]]

Hi everyone! I am trying to find out how to re-measure a feature according to a result, for instance, I've created a feature circle "c1" and characteristic "d1" and in the feature "c1" I placed on post-condition a code to check the error form like this:

result=getActual("c1").form

if result > 0.001 then

   activateFeature("c1")

   meausure()

end if

The idea is: if the result is bigger than 0,001 the measurement of the circle should be perform again, but it doesn't work.

I will really apreciate if anyone has an idea how to do this.

Thanks in advance//

What you are looking for is a method generally referred to as "retrace" (or re-scan).  This is very difficult to accomplish reliably. I am interested to see what our community has come on with on this topic.

I would probably follow instructions from the PCM examples in the help manual :

also the post adjacent to this at the time of this reply is asking the same question with nearly the same response.

I tried this code but it doesn't work because when I check for instance the form of a diameter and I choose option 3 to re-measure, it evaluates the diameter without measuring the circle again, because the loop is applied to the characteristic, not to the feature.

I may be way off target, with PCM can you "Delete Characteristic and Feature actuals" or "Delete actuals" (Delete actuals is for the feature) and force a rerun?

Some brief idea would be with the following code in the pre- and post parameter settings of the feature "c1".

Thank you very much Michael! I will try like this

Hi Richard!  I don't know if is possible to delete but maybe is not necessary, when you re-measure, the new values should replace the old one.

We just use two characteristics.  If a diameter of a bore is out of spec from a simple scan, it un-masks characteristics that re-capture the feature with an intensive long boring scan.  Concerning parts just automatically have an extra report page with the intensive scan and graphics.
