## Command Access:
> **Menu:** Tools \> Drafting Settings
>
> **Status bar:** Object Snap
>
> **Command:** SNAP
## Command Prompts:
> Specify snap spacing or \[ON/OFF/Aspect/Style/Type\] \<10.0000\>:
> Specify a point on desired side or \[keep Both sides\] \<Both\>:
Relative Glossary:
**Snap spacing:**
Activate Snap mode by setting specified value.
**ON:**
Turn on grid Snap mode by using current setting.
**OFF:**
Turn off Snap mode, but save current settings.
**Aspect:**
Specify horizontal spacing and vertical spacing.
**Style:**
Specify snap grid style of standard or isometric.
> **Standard:**
> Specify snap grid that is parallel to XY plane of current UCS. The X space and Y space could be unequal.
>
> > **Snap space:**
> > Specify snap space of all snap grids.
> > **Aspect:**
> > Specify the horizontal spacing and vertical spacing separately.
>
> **Isometric:**
> Specify the isometric snap grid at the original snap location of 30°and 150°. The horizontal spacing and vertical spacing of isometric snap should be equal. The straight line grid could not snap in isometric snap grid.
> The ISOPLANE system variables could determine the cross cursor types. They may be Left Isometric Plane (angle of 30°and 150°), Top Isometric Plane(angle of 90°and 150°) or Right Isometric Plane(angle of 30°and 90°).

**Type:**
Specify snap type:
PolarSnap or Grid Snap. It could also be controlled by the SNAPTYPE system variable.
> **Polar:**
> Specify the polar snap tracking distance. (It could also be controlled by the POLARANG system variable.)
> **Grid:**
> Specify the snap mode to grid snap, then the cross cursor will snap objects along horizontal direction or vertical direction.
