autocad 2017 does not save change settings

[Hybrid]

Hello. I have this problem: if I click on options>visualization>resolution accuracy of strings and try to set the value 2000, whenever I open an old file, I create a new one, autocad reopen, restart the pc, I always find the basic values of 100. Why? the rest of the other settings keeps them!

by memory:
is a value linked to the single file. for the old there is no solution, for the new you have to save it in the dwt

but I have a doubt: I opened an old design where the circles saw themselves as octagons and set the command viewris putting it at a very low value (5). all octagons have become curved. What's the story? I thought the number indicated how many segments to use to make the curve!

No. It is a value that indicates how the arches and circles must be approximated to speed up rigen operations, at the expense of visualization.
if in the dwg is represented the hole of a bolt of a wheel and you are looking at the whole car, in fact this hole will always be represented as a dot, whether accuracy is 5 and 20000.
If you zoom in on the wheel you will see polygonal (with accuracy 5) or circular (with accuracy 20000).
but if you see it polygonal, and give a rigen, you will see the hole again circulate, except then having to remake a rigen if you want to review the whole car.
was a parameter linked more than anything to the computing power of the old video/processor cards, when to make a regeneration it took a nap of time.

thanks for the explanation. what do you recommend setting by default? take into account that I work mainly on single pieces, max axle from a dozen pieces

I'd set it up at 20000. modern machines have no problems with long regeneration times.

Okay.
