Wrong slope for NPT hole tap?

Wrong slope for NPT hole tap?

Wrong slope for NPT hole tap?

(OP)
Can someone answer why Pro E does not show the correct slope on a NPT pipe tap when using the Hole Tool. It is half the value it should be; 17.899 degrees vs 3.579 degrees. This error has been in place for years in the program when at the same time, the feature's attribute data is correct. Look up the definition PTC; 1 on 16 slope based upon diameter. Minor issue I know, but ntl Absurd QC control for a $10k plus program.

Creo WF5 is certainly in a class by itself & my impression is PTC does not care....Mark

Sorry, got a decimal shifted 17.899 should read 1.7899 degrees. 3.579 is correct
