If you want to document Blender 2.5 features please edit pages under Doc:2.5/Manual.
If a "2.5" page doesn't exist please copy the text from 2.4x Manual and edit the new page (i.e. you should paste the wikitext from this 2.4x page to this new 2.5x page and then update the latter with 2.5 features)[edit] Grab/Move
Mode: Object and Edit modes
Hotkey: G
Menu: Object/Mesh/etc. → Transform → Grab/Move
[edit] Description
One of the fastest ways to move things in 3D space is with G. Pressing this hotkey will enter the “grab/move” transformation mode where the selected object or data is moved according to the mouse pointer’s location. The distance from the mouse pointer to the manipulated object has no effect.
[edit] Options
- Proportional Edit
- The circle of influence, changed by WheelUp
to make smaller and WheelDown
to make bigger, is shown and will move vertices within that circle by the proportional method/falloff chosen.
See the rest of the Manipulation in 3D space section for additional options available within the transformation modes.
[edit] Rotate
Mode: Object and Edit modes
Hotkey: R
Menu: Object/Mesh/etc. → Transform → Rotate
[edit] Description
Pressing R will enter the “rotate” transformation mode where the selected object or data is rotated according to the mouse pointer’s location. This mode uses the angle from the pivot point to the mouse pointer as the angle for rotation, so moving the mouse further from the object/data will give more fine-grained precision (i.e. the mouse movement will affect the rotation less, for the same mouse distance moved).
[edit] Options
- R (Trackball)
- Pressing R while already rotating toggles the rotation mode between a single axis rotation (either aligned to the screen or around a certain axis) and a two axis, “trackball” rotation. In “Trackball” mode, the rotation of the object is controlled by both the X and Y location of the mouse pointer, similar to the trackball view rotation mode. This can be a quick way to rotate an object into place, without having to keep changing the view rotation while adjusting. However, it is more difficult to use than the simple rotation.
See the rest of the Manipulation in 3D space section for additional options available within the transformation modes.
[edit] Scale
Mode: Object and Edit modes
Hotkey: S
Menu: Object/Mesh/etc. → Transform → Scale
[edit] Description
Pressing S will enter the “scale” transformation mode where the selected object or data is scaled inward or outward according to the mouse pointer’s location. The object/data’s scale will increase as the mouse pointer is moved away from the pivot point, and decrease as the pointer is moved towards it. If the mouse pointer crosses from the original side of the pivot point to the opposite side, the scale will continue in the negative direction, making the object/data appear flipped. The precision of the scaling is determined by the distance from the mouse pointer to the object/data when the scaling begins.
[edit] Options
- AltS (only in Edit mode)
- Scales along the selected normal direction.
See the rest of the Manipulation in 3D space section for additional options available within the transformation modes.
[edit] Precision
Mode: Object and Edit modes
Hotkey: Ctrl, ⇧ Shift
[edit] Description
Holding Ctrl and/or ⇧ Shift during a manipulation can be used to control the precision more finely.
[edit] Options
- Ctrl (Snap)
- Snap the transformation:
- For grab/move and scale, on 1 blender unit (or 10BU, 1/10 BU, etc., depending of the zooming view).
- For rotation, on 5 degrees step.
- ⇧ Shift (Precise)
- Allow finer transformation control but not by precise values (i.e. by fixed steps).
- ⇧ ShiftCtrl
- Snap the transformation on finer steps than with only Ctrl:
- For grab/move and scale, on 1/10 of the precision with only Ctrl (e.g. if with Ctrl you have steps of 1BU, with ⇧ ShiftCtrl you have steps of 1/10 BU).
- For rotation, on 1 degrees step.
[edit] Numeric transformations
Mode: Object and Edit modes
Hotkey: G/R/S, then + NumPad/- NumPad and 0 NumPad-9 NumPad or Keyboard 0-9
[edit] Description
When doing a transformation, instead of using the mouse (imprecise work), you can directly pass a precise numeric value.
Hit - NumPad (on a French keyboard, the minus is under the number 6 key, so you must use the Numpad) if you want negative values, and then a numeric value. You can see the values in the header of the 3D View. If you were using an axis constraint (global or local), the value is applied to that axis. If there is no axis constraint and you want to choose which axis to control, you can use ⇆ Tab to switch from any of the axis (a cursor appears after the value). You can also return to a mouse control with ← Backspace.
[edit] Cancel transformations
Mode: Object mode
Hotkey: AltG, AltS, AltR
Menu: Object → Clear/Apply → Clear Location, Clear Scale, Clear Rotation
[edit] Description
You can clear any transformation done in Object mode.
[edit] Options
- AltG
- Clear the location of the selection.
- AltS
- Clear the scale of the selection.
- AltR
- Clear the rotation of the selection.
[edit] Align
Mode: Object mode
Hotkey: CtrlAltA
Menu: Object → Transform → Align to Transform Orientation
[edit] Description
Align selected objects to a specific Transform Orientation.
