Set the precision for the measure tool in the application options. I am always extending this out. It currently has to be set each day at each document level. I just want to set it once, not reset it 50 time a day.
Also, the ability to set all measurements to DUAL UNIT in inches and mm.
The precision should apply to all fields in the Measure box.
In the example below, the precision (8 decimals) is not applied to the Position or Delta values.
Lack of precision can cause round-off errors. When incorrect values are used in Tube & Pipe runs, overcomplicated routes result because an aligment may be off in the 4th or greater decimal place.
Projecting or including geometry does not always resolve the issue for the pipe route.
While routing pipe a misalignment of 0.0000001 can turn what you think is going to be a straight-line pipe run into a pretzel. Then try and find where the problem is, when you can't set the Position and Delta unit precisions fine enough. If the piping requires umpteen decimal place precision while routing, Inventor needs to have an option to show that same precision when checking X/Y/Z locations and deltas.
