Imperial feature on metric part 1

[JHTH]

Is there a more cunning way of putting an inch-size feature onto a metric part than multiplying or dividing your mm values by 25.4?

In my example I'm mating to a fairly unique optical thread form of 1.035"-40 so for the thread diameter I'm entering 1.035*25.4. In my previous software (Inventor) I could enter '1.035 in'. Is there an equivalent in NX?

Thanks in advance,

JH

When you enter the value for the feature you can set the value and units like 100mm or 3.937in
the system converts it to the bas units of the part when you look at the expression table.

Haha! I'd written it with a space before, which is why it didn't work... So close and yet so far.

Thanks!

Or if you're going to be creating a series of features/operations using an alternate unit of measure, go to...

Analysis -> Units...

...and simply select from a list of pre-defined alternative measurement schemes or you can even set-up you own custom ones (ever need to compute velocity in 'Furlongs/Fortnight').

Once you've selected or defined an alternate unit of measure, the system will now act as if that was the part defualt until you set it back to normal. Now the units of the part file have NOT changed, just that the system will pretend that it did and all your entries will be recorded as such. Note that this will ALSO allow you to change the units for the items UNDER the Analysis menu. So lets say you have a Metric part file, but you'd like to get mass properties in Imperial units. Therefore use the above steps to set the desired units and then do your 'Measure Bodies' operation or make the Measurement that you need. Or you might have this scenario; you've modeled in Inches but would like to get a volume in cubic feet, this is how you would accomplish that.

Now remember, this does not alter the part file as this is just a temporary change nor will this setting be retained when you exit the session and start a new one.

Anyway, give it try as it might be more efficient to do it this way than to remember to alter your parameters for every entry you make.
