Ok, so i ran your program thru a script i wrote a while ago to check the accuracy of arcs ( as i say we have had this problem occur at work ) The output is below.
As I suspected the warnings you are getting is when an arc start, end and center point are not perfect.
Just note the “N” numbers for each error below. They are the same as the Location numbers in your warning screen from above (except for line N65 - which was the worst deviation of them all - strange).
Since the file still ran fine then i think that means the 1F controller is set to tolerate deviations greater than .003 inch on arcs. So it is nothing to worry about unless you want to do super accurate work.
I will test some more tomorrow on my machine.
tclsh check.tcl -test “arc test.nc”
