We use holes a LOT, and if we need to remember what a particular hole is tapped with (i.e. 1/4-20), measuring the hole itself is of no use, because Inventor uses the Tap-Drill diameter from its spreadsheet. Unless you have the tap-drill diameters commited to memory, it doesn't do a lot of good to measure that.
My idea is to somehow have a way to measure the threading on a hole, rather than dig down to the assembly/part find the particular hole you're looking for, edit it and check what threading you have it at.
Could this be added to the measure tool? Distance, Angle, Loop, Area... Threading?
Just a thought...would save a lot of digging.
Cheers!
