I would be happy to script it… I found something called precision, but I do not think that it is related to the display. I always get 2 decimal points displayed in the 3D View.

> Hello, I’d like to add more significant digits to fiducial points when saving to a FCSV file. I can set the values I want using Python, but the Markups table and the output FCSV file show the default precision. I have tried changing the precision under Application Settings-\> Units but this doesn’t impact the fiducial points. Is there a way to do this? Thank you for your help. Sara
