Mirror, Clone & Multiply

Three Voxel Mode features make more of what you already have. Mirror sits in the Modify accordion beside Move, Rotate and Scale; Clone has an accordion of its own, Multiply; and Extrude lives in the Extend accordion just below it. Mirrors and clones are live: the copies keep following the shape they came from until you deactivate or flatten them.

Mirror mode

Mirror is a mode, not a one-off action. Click it and it stays on under every other tool until you click it again: new shapes get a live mirrored copy, deforms happen on both sides of the mirror, and deleting a shape deletes its reflection too. Turning it on also opens the Numeric window, where its settings are. If no plane is chosen when you turn it on, X is switched on for you, since a mirror with no plane would do nothing.

While the mode is on, a Mirror Settings section appears at the bottom of the Numeric window, under whatever else the window is showing:

Control	What it does
Mirror across X / Y / Z	The planes new shapes and tools are mirrored across. Turn on more than one to mirror into several quadrants at once. Shapes that are already mirrored keep their own planes.
Plane positions	Where each mirror plane sits along X, Y and Z, in metres from the origin. Moving a plane also moves the mirrors already made on it.
Mirror Selected	Mirrors what is selected now, so shapes made before you turned the mode on get their mirrored copy too. Needs a selection.

In the Top, Front and Side views each active plane is drawn as a line with a circle at either end. Drag a circle to slide the plane; hold Ctrl while dragging to snap to the move step.

How linked mirrored copies behave

A shape and its mirrored copies form a linked group. In the Voxel Tree every member shows a link icon at the right of its name. Hovering it on the original reads “Mirrored: its linked copies follow every change to it”; on a copy, “A linked mirrored copy: it and its source change together”.

• Clicking any member of the group selects the whole group.
• Move, resize or deform the original and the copies follow on the far side of the plane.
• The original has a fold arrow even with no children; it hides or shows its mirrored copies in the tree (Hide this node's mirrored copies).
• Right-clicking a live copy just tells you A live copy: edit the original and it follows. — edits go through the original.

Clone (Multiply)

Select one or more shapes, open the Multiply accordion and click Clone. It makes copies of the selection, each moved, scaled and turned a step further than the one before. The button is disabled until something is selected. The settings appear in the Numeric window and the copies update as you type.

Control	What it does	Range
Grid checkbox (before the label)	Make a grid instead of a row: a count along X, Y and Z, each including the original. The offsets then become the spacing along each axis.
Number of Clones	How many copies to make, each one step further than the one before. With the grid on, this becomes three counts; 3, 2, 3 makes 18 in all.	1–1000; grid 1–100 per axis
Offset X, Y, Z	How far each copy moves on from the one before.
Scale X, Y, Z	Each copy's size against the one before, about Center. 100% keeps it.
Rotation H, P, B	How far each copy turns on from the one before, about Center. Combine with an offset and the copies climb in a spiral.
Center X, Y, Z	What the copies scale and turn about, measured from the middle of the selection. 0 turns them in place.
Apply	Keeps the copies. Return does the same; Esc, or clicking Clone again, drops them.

Once made, the window counts the live copies: they follow the original until it is flattened, or deactivated from the Voxel Tree.

Making copies ordinary

Live clones and reflections stay tied to their original. When you want to change one copy on its own, or simply stop the copies following, there are two ways out, both on the original's right-click menu in the Voxel Tree:

Menu item	What it does
Deactivate (keep the copies)	Turns the node's live clones and reflections into ordinary nodes beside it, where they are now. They stop following it and can be edited one by one.
Flatten	Bakes the node and everything under it, copies included, into one object. The parts are gone for good, though Undo still takes it back.

Extrude (Extend)

Extrude, in the Extend accordion, pulls a face of the model out and leaves the extruded outline behind it. Select the surface to pull with Select (Face) or the mask, then drag in a view — or, with nothing selected, simply click a flat face and drag it out. Hold Ctrl to keep the drag straight out of the face; in a view looking straight at the face, drag up or down.

Control	What it does
Extent X, Extent Y, Extent Z	How far the face is pulled out, in world axes. Pulled into the model, it digs straight in instead.
Apply	Keeps this extrusion (Return does the same) and leaves the tool on for the next face. Esc drops it. Click Extrude again to put the tool away.
