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.
Elements of the Snap Bar
- Snap Spacing Range Displays the range of snap spacing values. The range updates automatically, depending on the model size and zoom level.
- Snap Spacing Value Displays the current snap spacing value. The snap spacing automatically updates as you zoom in and out. Enter a value to override the automatic snap spacing.
- Slider Shows the position of the current snap value on the scale. Drag the slider to override the automatic snap spacing.
- Units Glyph Displays the current document units. Pause the cursor over the glyph to display the units list. Select from the list to change the units.
Dynamic Snap Spacing
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.
Override the Snap Spacing
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.
Set the Units
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.
There are two Inch unit systems:
- In Arch (Inch Architecture) The snap range and spacing values adjust in fractional inch increments.
- In Eng (Inch Engineering) The snap range and spacing values adjust in decimal inch increments.
