The Snap Bar displays in the lower right corner of the graphics window. It displays the document units, snap value range, and snap spacing. The snap range and spacing automatically update as you zoom in and out.
Snap spacing is used for sketching and modeling. You can turn snapping off by clicking the Snap Mode icon on the status bar. See the Status Bar topic for more information.


The Snap Bar dynamically updates the snap range and value based on the model size and current zoom level. The snap range becomes small when you zoom in, and large when you zoom out. The default snap spacing value is the first division of the snap range.
To override the snap spacing value. drag the slider, or enter a value. The snap range still updates when you zoom, but the snap spacing does not change unless the value is outside the range. If your snap spacing is too large or too small for the zoom level, the value temporarily updates.
For example, enter a value of 25 when the range was 0-100. If you zoom in until the range changes to 0-20, the snap spacing is greater than the range, and the value changes to 5. When you zoom out so that the range includes 25, the snap spacing changes back to the original value.
The units system is set for each document. Pause the cursor over units glyph to display the units list. Select from the list to change the units system.
