Brush reference

Shapeaway has nineteen brushes. The first ten are on the number keys; the other nine are on Shift with a number. Hold Space for the radial tool menu, or rebind any of them in Settings.

Brush	Shortcut	What it does
Add	1	Builds clay up under the brush, like pressing on a small pellet of clay
Carve	2	Removes clay under the brush
Smooth	3	Evens out bumps and blends forms together
Flatten	4	Presses the surface towards a flat plane, set where the stroke starts
Inflate	5	Pushes the surface out along its own direction, swelling forms evenly
Pinch	6	Pulls clay towards the middle of the brush, tightening creases and sharpening ridges
Grab	7	Drags a whole region of clay with the pointer, for changing proportions without sculpting
Shape	8	Stamps a solid where you click: a ball, cube, cylinder or ring, standing up along the surface
Paint	9	Brushes colour onto the clay
Mask	0	Paints a mask that protects the clay from every brush, paint included
Clay Strips	Shift + 1	Lays flat strips of clay along the stroke, building form in layers the way you would with real clay strips
Crease	Shift + 2	Cuts a sharp groove along the stroke, or raises a sharp ridge when inverted
Snake Hook	Shift + 3	Pulls clay out along the stroke, tapering as it goes: horns, tentacles, tails, spikes
Layer	Shift + 4	Raises (or lowers) the surface by an even height, without stacking up where strokes overlap
Noise	Shift + 5	Roughens the surface with a fine noise pattern: skin, stone, bark
Trim	Shift + 6	Cuts down only what stands proud of the plane under the brush, and never fills hollows: planes and bony edges
Polish	Shift + 7	Flattens towards the brushed area’s own plane while keeping edges crisp: polished, hard surfaces
Dam Standard	Shift + 8	A narrow, sharp, pinched crease: lids, lips, wrinkles and seams
Move	Shift + 9	Grabs and moves the surface

Every brush works on detail meshes as well as clay. Hold Ctrl (or use the pen’s eraser) to invert a brush, and Shift to smooth.
