The 3D Viewport is used to interact with the 3D scene for a variety of purposes, such as modeling, animating, texture painting, etc.
The header contains various menus and controls based on the current mode. Its items are split into three groups:
- Transform Orientation Comma
Used to change the Transform Orientation, which affects the rotation of the transform gizmo.
- Pivot Point Period
Used to change the Pivot Point, which affects the location of the transform gizmo.
- Snapping Shift-Tab
Offers options for snapping items to others that are nearby. You can hold Ctrl to toggle snapping on/off temporarily (as long as the key is held).
- Proportional Editing O
Used to smoothly transform unselected items that are near the selected ones. See Proportional Editing.
Display & Shading
- Object Type Visibility
Change which types of objects are visible/selectable in the 3D Viewport. See Object Type Visibility.
- Viewport Gizmos
Change how gizmos are displayed in the 3D Viewport.
- Viewport Overlays
Change how overlays are displayed in the 3D Viewport.
- X-Ray Alt-Z
Make the whole scene transparent, allowing you to see and select items that would otherwise be occluded. This is a shortcut to the X-Ray option inside the Viewport Shading popover.
In Pose Mode, this same button controls a different setting with its own separate on/off state. Rather than making the scene transparent, it shows the armature in front of any geometry.
- Viewport Shading
Change the shading of the 3D Viewport.
The Toolbar contains tools depending on the current mode (for example, modeling tools in Edit Mode, brush tools in Sculpt Mode...).
See Tools for more information.
