You could overwrite the dimension.
There's no need to overwrite the dimensions. In fact it's a bad suggestion (I had something stronger written but deleted it). See How do I change my units from inches to mm (or vice versa)?. The title doesn't directly direct your issue, but the information is there.
Whassamatta Glenn... Afraid of getting moderated?
One point first, the smaller ANSI threads are drilled with lettered or numbered holes, so I'll suggest leaving these as decimal.
One solution would be to set the drawing's units to inches as the primary unit and mm as secondary.
Then you can override the dimensions that need fractions on the Other tab.
Downsides are it's a kludge and all of your dimensions will have reversed units.
And yes, Mr. Schroeder is correct on not overriding dimensions.
I'd rather not have this option at all, but if there is a reason for it someday, somewhere somehow, then I'll say at least move it to the Other tab (or even better put it on the Never tab ).
Besides, you can't override hole callouts.
Hi, Thank you all I appreciate.
1- I would love to apply what fox recommend but is not possible....
2- the primary units remain metric, second will be inches
3- I find a solution to add the second hole diameter and set in inches type fraction is the only way what I find it
4- I will not overwrite the dimensions...please is not a joke.
5- I know how to change units from metric to inches and vice versa, I was interested in something more fast reliable and of course parametrical. THANK YOU.
thank you, so much I appreciate, is what I search.
