Wrong Hole / ThreadedFace thread info

[billing5GPFL]

Hello forum

i have a part with 2 holes as shown in the pictures

the info for the one hole M10 are correct

 

the info for the 1/4-20 are not

 

ThreadedFace.Geometry.Radius is correct in both cases, the hole are actual that size

in the 1/4-20 ThreadInfo i looks like the parameters major / minor which are the diameters have values from the close to the radius.

or inventor did the hole double the size or ...

i hope i explained that correctly.

Matches the Threads.xls table in design data:

The document settings control the appearance of the tapped holes...It is set to Minor diameter by default.

no arguments there, you are correct about that but

notice that Geometry.Radius (thats the actual hole Inventor puts on the model) is 0.2 and MinorDiameterMin/Max is also 0.2 or near it, perfectly normal, but the one is RADIUS and the other is DIAMETER, so i am guessing one of them is wrong

That little window, I'm not certain it is converting the Inch units? You have Minor Diameter = 0.196 inches x 25.4 = 4.9784 mm diameter or 2.4892 mm Radius (which is what is measured). The geometry.radius appears to be displaying CM, so 2.4892/10 = 0.24892 cm.

The metric version appears to all be converting correctly. Just not the inches in that little program?

Number in the 1/4-20 is imperial: inch.

Debugger Watch only show number.  No units.

Hey, yes you are correct

they are in different measuring units !

Thanks
