3DS max, shift issues for small-sized objects

Valentris

Greetings!

I got a question regarding to 3Ds max (2015 in my case) coordinate rounding topic which seems pretty fundamental, yet I somehow missed it before:

Working with quite a small sized objects (> 0,01m) I find out that simple act of clicking at coordinate position fields (X/Y/Z) leading to object in viewport making a shift in corresponding direction, and it happens for all sub-objects as well (one time for each of the objects).
My questions are: does it happen because of coordinate rounding? How to prevent this kind of shifts?

Thanks.

You don't usually get issues at 2-3 decimal places. What are your system units set to?

Valentris

It was set to inches, and as I can see smallest units (mm) cause strongest shift (with no visible shift for meters/km).

you can change the precision settings in unit setup - you'd have to check the docs for a decent explanation because I've not touched that stuff in 12-13 years. 

Fwiw the unit setup I use is to set system units to cm and ui units to generic. I find you can work up to 9.9km and down to a hundredth of a mm without any real inconvenience or precision issues.

Many thanks, I'll try this settings

Try adjusting your spinner precision in the preferences.
