System units 3ds max ..distance from origin?

[NOPE]

Does anyone know what is this slider at System Unit setp in 3ds max -Distance from origin ...

I need to know exactly what it does ...

I work in system unit 1unit=1mm (metric scale)

 

but dunno what is this slider for ..as well as resulting accuracy ..

Did you take a look at the Max Help file?

Origin Slider, Distance from Origin, Accuracy

These controls provide a system unit calculator to help you determine the unit scale for your project. The resolution of measurement diminishes as the distance to the origin of space increases, so you need to consider space granularity when you choose a scale for your project. If you're modeling an island, for example, this calculator can help you determine the smallest object you should model on the island. In other words, don't use a unit scale of millimeters if you plan on modeling an island that's many miles across.

 

When you use the slider or the text field to enter a distance from the origin, the Resulting Accuracy changes to show what the round-off error will be at that distance.

 

These controls don't change the unit settings in 3ds Max. They don't reflect the extents of the current scene, either.

 

 

Origin Slider

Move the slider for interactive feedback of distance and accuracy. Right-click the scale to reset the slider to 0. Dragging the slider displays the last slider position as a small square on the scale markings.

The slider covers distances from 0 to the maximum distance that's accurate to one system unit.

 

Distance from Origin

 

Enter the maximum distance you want to use in your project to determine the maximum accuracy, which is displayed in the Accuracy field. Values consider current settings for system scale and unit.

 

 

Note

When you type a distance, you must press ENTER to update the Resulting Accuracy field. Pressing TAB simply moves focus to Resulting Accuracy, without doing the calculation.

 

Resulting Accuracy

 

Enter the minimum resolution you will use to determine the maximum size or distance that is most practical. Values consider current settings for system scale and unit.

 

For example, if units are in feet and decimal inches in Customize menu > Units Setup, and you type (1', 1 foot) in the Accuracy field, a value of 22369620'0.0" is displayed in the Distance From Origin field. If you move an object that's one foot across, at this distance away from the origin of space, a round-off error will occur, and the shape of the object will be compromised.

 

 

As long as Ive made sure my scene is centered around 0,0,0 I've never changed these settings... Has anyone ever changed this??

Yes I read the help .. but still can`t understand this very well ..

 

The slider covers distances from 0 to the maximum distance that's accurate to one system unit.

 

I think it`s something like that : If the scene is too big - like they say if you modeling island and if you working in mm errors will occur in the accuracy...

and if you making something small like a pen ..but work in km again there will be errors.And it you must keep your scene in the center ...X-0 Y-0 Z-0.

Not shure is it like that but...

So it`s best to leave the slider in it default position maybe.

yeah your pretty much right about the island and pen scenario.

and basically the slider is nothing more than a calculator, so changing will do absolutly nothing to your scene, all it does is tells you how accurate one unit will be X amount from origin

thanks !!! very helpful indeed.
