When you’re in the Voxel Room, there are a robust set of tools that you can use for sculpting and to perform different operations.

They are located on the left-side tool panel.
You can always obtain access to the Voxel Tool Panel by pressing “Spacebar” anywhere on the screen. As with any other panel, you can dock it for your convenience.

Grow: Increases or decreases the surface beneath the cursor. None of the Brush Alphas having any effect on “Grow”, just the brush size and the intensity. Press “LMB” and move the mouse to produce an expanded section.
CTRL+RMB to produce a contracted section. On the top panel, the “Growth power” slider controls the intensity of the expansion and the “Thaw power” slider controls the intensity of the contraction.
Smooth: A dedicated tool for evening out any irregular areas of a sculpture. See also Smoothing Options.
Fill: Fills any cavities or voids that you apply the brush to. Its action is similar to the “Smooth” tool, but more precise. It’s useful when you want to make cavities shallower, but not fully level with the rest of the surface. It sometimes requires very high intensity settings to fill areas.
Vox Clay: Lets you blend expansive strokes quickly on the surface of your model. It will also simultaneously smooths the surface after you’ve applied it.
Carve: Lets you place high peaks and deep gouges quickly on your model, but with no smoothing.
Blob: Very much like the “2D Paint” tool, but with fewer options.
Airbrush: This tool provides a very controllable way to add volume to your model. Unlike the Clay tool, it constantly grows underneath your brush as you press the LMB, regardless of mouse or stylus motion.
Build: This tool is similar to the “Grow” and the “Airbrush” tools. But while the Airbrush will continue to build while holding down your cursor, “Build” doesn’t do that. You have to move it, like the “Grow” brush. However, with the Build tool you can determine the Brush interaction by means of the Brush Alphas (no smoothing is applied).
Extrude: This tool is very similar to the Carve tool, but it includes intense smoothing.
Sphere: This tool is a very quick way to create bubbles, bodies, eyeballs, etc. The size of the sphere is dependent on the size of the brush. You can also make it dependent on stylus pressure: click on the icon near the Sphere extrusion slider. The maximum size will be the maximum size of the brush.
You can create separate spheres and long, “pill-shaped” cylinders rounded at the ends, by Left click dragging in open space. Because of this, regular, “button based” viewport navigation needs to be accompanied by holding down the “Alt” key.
2D-Paint: This tool paints voxel thickness on two axes which you specify by right-clicking anywhere in space or on the surface of an object. Notice first that, as you rotate the view and move the brush, it’s moving along the two axes. When you change your view, new strokes will always face the camera. Pick any Brush Alpha you like and just paint!
It also has an important option on the top tool bar:
“Double sided”. With this checked you can paint double-sided strokes.
Plane: This tool acts just like a carpenter’s wood plane does. It will scrape the volume away, from the set position as well as the normal of the brush cursor. You set the brush cursor’s position and normal by clicking and holding the RMB and then dragging along the surface of a voxel object. There are five modes by which you decide the position of the brush:

  • 1. Pick point & forward direction: This will place the cursor at the last location you used the RMB, facing toward the camera.
  • 2. Pick point only: This will place the cursor at the last location you used the RMB only. Its direction is based on the settings in the parameters tab.
  • 3. Pick point & direction: This will place the cursor at the last location you used the RMB, and its direction will be based on the average normals of the voxels that your brush covers.
  • 4. Pick point & direction (local): This will place the cursor at the last location you used the RMB, and its direction will be based on the single normal of the voxel your brush is centered on.
  • 5. Navigate: Lets you navigate the viewport. This can also be done while holding the ALT key.

Now we’ll continue with the other tools:

Scrape: This tool is not affected by pens, just the Size of the brush and the Intensity. It’s very similar to the Flatten tool: it flattens the surface beneath the brush.

Vox Hide: This tool has been improved greatly. You can now hide on a per voxel basis. This lets you to paint the areas you wish to hide, while it also respects other selection methods, like drag rectangle, drawn contours, etc. This new method of hiding makes it much easier to create many hard edged surfaces for objects. The tool also has a few other functions, which you will find in the Voxel menu. They are listed as follows:

  • Unhide all: Unhides any hidden voxels. any voxels you have hidden.
  • Separate hidden part: Creates a new Layer in the Voxtree and places the previously hidden voxels into the newly created Layer.

Continuing with the other tools, they are:

  • Invert hidden: Inverts hidden voxels.
  • Delete hidden part: Deletes those parts which are not visible.

Pinch: This is great for making very nice tight edges, cavities and peaks.

Smudge: This tool drags the surface topology along with the brush. It’s great for producing wrinkles on a character or a piece of clothing.

Voxel Plane Tool: This video provides an updated demonstartion of the Plane tool in 3DCoat's Voxel Workspace. It shows how it can be used as a versatile cutting_trimming tool.
