Hi FriedhelmK,
I know it was you who gave me the tip. But I thought that nonetheless you might have left the value for the number of decimal places shown at the default setting of six. As I wrote earlier, when I set that value to six I got the exact same output values as you, so that would have explained the difference in your output and mine. But if you say your value is set to "all" I will take your word for it.
But this is frustrating. I have a second computer with Creo Elements / Direct Modeling Express installed on it and I repeated the process there and got the same values as what I get on my main computer. What am I supposed to think here? This may be some kind of bug in the program.
