The Interface
The ProGrids Panel displays the following buttons and options:
1. Snap Size and Settings 
Click this button to open the snap settings window, where-in you can set snap increment and other settings.
Units are in meters by default, or you can choose inches, feet, etc. See the Preferences section for more details.
Hint Use the
+and-keys to quickly change the Snap Size
| Setting | Description |
|---|---|
| Snap Value | Set the increment to snap objects to in world coordinates |
| Major Line Increment | How many lines to show between highlighted lines |
| Snap on Scale | When enabled, applies snapping to object scale values |
| Snap as Group | When enabled, multiple selected objects retain their relative positions to one another when moving |
| Grid Units | Defines the unit of measurement that snap value is measured in |
| Angle | When in orthographic views an additional line is drawn at this angle |
| Predictive Grid | When enabled, ProGrids will automatically set the rendering grid plane according to object movement |
2. Grid Visibility 
Toggle the grid visuals on or off.
Note that objects will still snap with grid visibility toggled off.
3. Snapping Enabled 
Enable or disable snapping to the grid when moving objects.
4. Push to Grid 
Move all selected objects to on-grid positions, on each axis.
5. Lock Grid 
6. Set Grid Plane X 
7. Set Grid Plane Y 
8. Set Grid Plane Z 
9. Perspective Grid 
Angle Visibility 
Toggle the visibility of the angle guides when in orthographic scene rendering mode.
Angle Size: Set the angle used for the Angle Guide- The Degrees used for the Angle Guideline visual
- If you need to ensure multiple items are fully on the Grid, use this button
Perspective View Only: The following buttons only effect how the Grid is displayed in Perspective views:
X Grid: Show the X Grid- Choose this mode to display a Grid perpindicular to the X axis, in the Perspective view
Y Grid: Show the Y Grid- Choose this mode to display a Grid perpindicular to the Y axis, in the Perspective view
Z Grid: Show the Z Grid- Choose this mode to display a Grid perpindicular to the Z axis, in the Perspective view
Z Grid: Show the full 3D Grid- Choose this mode to display the full 3D Grid, in the Perspective view
Grid Lock/Follow: Choose whether the Grid “follows” the selection, or is locked in place- See “Using the Perspective Grid” for more details
Snapping Multiple Objects:
When you select and move a single item, it will snap to the grid exactly. However, when you have multiple items selected, and move them all at once, ONLY the active object will snap to the grid- all other items will simply “follow” the active object.
For example, if the active object moves 1 cm to the left, 2 cm down, and 8.5343843 cm forward- so will all the other selected objects, REGARDLESS of whether their new position is on the grid or not.
This is very useful for when you are moving many objects, but only want a certain one to snap.
If you need to make sure all selected objects are snapped to the Grid, click the “Push to Grid” button (see “The ProGrids GUI Panel”).
Axis Constraints:
ProGrids has 2 Axis Constraint modes: “No Constraints”, and “Use Selected Axis”. “No Constraints” is the default mode, and will automatically snap objects on ALL 3 axis, always. “Use Selected Axis” will constrain snapping to only the currently selected axis (ie, when you click and drag on just the X, Y, or Z arrow in Unity).
You can hold down the S key to swap into the alternate Constraint Mode- letting go of S will swap back into the default Constraint Mode.
Note that you can choose which Axis Constraint Mode is the default, in the ProGrids Preferences- see “Customizing ProGrids”, below.
Keyboard Shortcuts
Keyboard shortcuts are great- use them!
+ or - : Hit the “plus” or “minus” key to make the grid larger/smaller by one increment (see “Customizing ProGrids”)
[ or ] : Use the bracket keys to nudge the X, Y, or Z grids perpendicular to their facing direction, by one increment.
S : Hold S to swap between Axis Constraint Modes (see “Axis Constraints”, above)
