Move, Rotate, Scale & Pivot

·

Voxel Mode places, turns and resizes shapes with an on-screen gizmo. The Move, Rotate and Scale buttons sit at the top of the Modify section of the Voxel sidebar. Under the sidebar's sections are the controls that shape how every one of those tools behaves: the X / Y / Z row with its axis locks, the four pivot buttons, and snapping.

The gizmo tools

No handles are shown until you pick a tool, so the viewport stays clear while you block out a form. Pick a tool and its gizmo appears on the selection; click the same button (or press the same key) again to put the handles away. Only one gizmo is ever shown at a time.

ToolDefault keyWhat it does
MoveTMove the selection with the gizmo: drag an axis arrow to slide it along that axis.
RotateYTurn the selection with the gizmo. Its axes are named H, P and B (heading, pitch and bank).
ScaleHResize the selection with the gizmo. The drag is deliberately gentler than the cursor, so small forms do not jump in size.
BoundsShift+HResize by dragging the corners of a box that hugs the selected node. The corner follows the cursor directly. Bounds has no sidebar button; use its key.

These keys only act in Voxel Mode, and they can be rebound. Outside Voxel Mode, T and H keep their usual jobs.

Holding Ctrl while you drag a handle snaps the drag for as long as the key is held, whether or not snapping is turned on. If the node you drag has children, Ctrl also edits that parent on its own: its children stay where they are in the world.

A locked node can be moved and turned but not resized, so Scale and Bounds show no handles on it. When you are done, press Apply in the Numeric window (or Return) to finish the edit and put the tool away.

Moving several nodes at once

The gizmo sits on the active node, but everything selected moves as one unit. The other nodes get the same change rather than the same position, so a selection keeps its layout: a turn swings them around the pivot together, and a scale spreads them apart in proportion instead of piling them on top of each other. The selected nodes do not need to share a parent.

Pivot

Four buttons choose the point the gizmo sits on, which is the point a turn or a scale works about. One of them is always on. The Twist tool uses the same choice.

ButtonWorks about
MouseThe point last clicked on empty space in a view. Clicking there leaves the selection selected.
SelectionThe middle of everything selected.
PivotThe selected node's own origin.
OriginThe world origin.

Bounds always works from the node's own origin, whatever is chosen here, because its box is measured from that point.

Axis locks and the X / Y / Z row

The row above the pivot buttons has one button and one field for each axis. Under Rotate the buttons read H, P and B. Each button is the tool's lock for that axis. A lit button means the axis is free. Click it to lock the axis: the gizmo drops that handle and no drag can change that axis. Click it again to free it. If you lock all three axes, the tool treats them all as free, so the gizmo can't disappear without explanation. Each tool keeps its own locks. Bounds has no per-axis locks.

The same locks appear beside the fields on the Move, Rotate and Scale pages of the Numeric window, so a locked axis is locked in both places.

The fields follow the selected node and edit it: position under Move, size under Scale and Bounds, and the turn in degrees under Rotate. Drag left or right on a field to slide its value (Shift for finer steps), or click it to type a value, with a unit or simple math such as -10 cm or 90 + 45. The small box at the end of the row cycles what the numbers mean:

LetterMeaning
RRelative: how far the node has moved, turned or grown since the last drag began. Type a value to move it that far from there.
LLocal: the node's placement in its parent.
WWorld: where the node is in the scene.

The row shows something different at two moments. With the mouse over a Top, Front or Side view, it shows where the mouse is in the world, and the axis that view cannot show is left blank. While you scale, each axis is shown as a percentage of its size when the scale began, where 100% means no change.

Snapping

Beside the Units dropdown are a checkbox and a step field. Tick the checkbox to round the current tool's drags and typed values to the step. Each tool keeps its own setting, so turning on rotation snapping doesn't affect moves.

ToolStep
MoveThe snap step, as a length (one value for all three axes).
RotateThe rotation snap step, in degrees, from 0 to 180.
Scale / BoundsThe snap step, as a length. Bounds shares Scale's setting.

The step field is greyed out while snapping is off. Holding Ctrl during a drag snaps to it anyway.

Move, Rotate and Scale with falloff

While Move, Rotate or Scale is on, its page in the Numeric window ends with Falloff controls. Each tool keeps its own setting. With None, the tool applies in full everywhere, as usual. Pick Linear or Radial and, with something selected, the tool becomes a falloff edit. The page is titled Move with falloff, Rotate with falloff or Scale with falloff. The gizmo now drags a handle, and the selection is moved, turned or scaled more in some places than others. The page's fields show the offset, the turn, or the scale as a percentage, measured from where the edit started.

ControlWhat it does
FalloffNone applies in full everywhere. Linear ramps along a range. Radial ramps out from a centre, like a sphere of influence.
ShapeLinear only: four buttons for where the ramp starts. Choose the near end, the far end, the middle, or both ends.
Presets, Ease in, Ease outHow the ramp leaves nothing and how it arrives at full. The preview beside them shows the weight across the range.
RangeAutomatic runs the range across the selection. Fixed lets you set it: for Linear, drag the two circles on the axis line in the views. For Radial, use the Radius and Center rows, or right-drag in a Top, Front or Side view.
AxisLinear only: the world axis the range runs along.
ModeDeform bends the whole selection as one piece, and Apply keeps it as a locked group. Rigid moves, turns or scales each selected part whole, by the falloff's weight at its centre, so nothing bends.

Apply or Return keeps the result as one undo step. Esc puts everything back. Bounds has no falloff. Taper and Drag Net are ready-made versions of these: Scale with a linear deforming falloff, and Move with a radial one. See Taper, Twist, Bend, Shear & Drag Net.

Cut, copy and paste

In Voxel Mode, these keys work on whole nodes:

Default keyWhat it does
Ctrl+CCopy the selected nodes, children included.
Ctrl+XCopy the selected nodes, then remove them. Undo puts them back in their place in the tree.
Ctrl+VPaste. With a node selected, the copy goes in after it. With nothing selected, it lands back where it came from, so a cut followed by a paste leaves the scene unchanged.

What you paste becomes the selection, so the next drag moves the copy rather than the original underneath it.

Tip

Alt-click in a view to paste at the point you click. In a Top, Front or Side view, the copy keeps its depth and moves within that view's plane. In the perspective view, it lands on the surface you click.
