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. File Load: Units Mismatch Dialog Change the system unit scale. > Open, Merge, XRef, or drag geometry from a file with a different unit scale. This dialog appears when you open or merge a file that has been saved with system unit settings that are different from those of your current 3ds Max session. The default system unit setting is Inches. If you open a file with the system unit set to meters, for example, you will see this dialog. File Load: Units Mismatch Dialog | 7815
