Add/split: This tool lets you simply add edges by pointing and clicking in the location you would like to add the edge. See also Add/split addendum.

Select

  1. Select tool has selection modes, allowing you to select Vertices, Edges and Faces.

Select Transform:

Select Path: Define a seam for Unwrapping by designating a path composed of vertices you select in linear order. Press “Enter” when you have established your path to create the seam.

Quads: The basic usage of this tool allows you to select an edge of a polygon, and then drag out and click the placement of the edges for a new polygon. See also Quads.
You can use 4 different methods for defining new topology, one quadrangle at a time. They are: 2-clicks method, Parallel, Direct and Trapezoid.




Points to Polygons: Use this tool to create either quadrangles or triangles, point by point hovering the mouse cursor over the area defined by the points and “Right-Clicking” to establish the new polygon. You can move vertices by “Right-Clicking” and dragging it.
Use Special Submenu to clear points.

Cap: Hovering the mouse cursor over a hole surrounded by connected topology and “Right-Clicking” creates a “pole” and the connecting triangles which serve to close the hole.

Strokes Draw strokes and press ENTER to create a polysurface. Press ESC to clear strokes. Draw with CTRL to add splines, and connect and break existing strokes. You can also draw closed splines/curves. Start drawing in empty space to slice. You can join several slices or circles with a single stroke to create cylinders.

  1. Curves/Strokes: Create topological “cuts” which form loops through an area of a model, or draw freeform splines with an even spacing of vertices which you define in advance. One use for this tool is to define a surrounding cylinder of polygonal rings by first drawing a sequence of loops (start drawing in empty space and finish in empty space), then draw a freeform spline along the length of a model “appendage” (arm or leg), and pressing “Enter” to finalize and create a cylindrical set of faces which define the appendage.

There are a few commands local to this tool under Special SubMenu:

  1. Clear. This will clear all draw lines.
  2. Smooth. Smooths all current drawn lines.
  3. Delete. This will delete your currently selected line.

RFill: This video demonstrates the usage of the RFill tool in 3DCoat's Retopology workspace. It may be renamed “Quad Fill” in the near future, as it fills openings in the mesh with quads.
This is a Quad Fill tool, designed to fill holes in a mesh with proper topological flow.

Knife Cut a face by Knife. Draw the line and press ENTER or DblClick. Also, you can draw a polygon, by two points.

Smart Retopo The video shows what we call Smart-Retopo feature, based on using the Curves toolset. Smart-Retopo Tool (Using Curves)
Smart Retopo - mode Quadrangulation In mode Quadrangulation you must click on Apply 2 time.

Spine Tool Extrude selected faces along Arc. Angle and Axis of the Arc can be edited by a Transform Gizmo. You can edit the Quantity of Segments and Scale factor. In Spline Mode, you may LMB drag points to move in 3D space and use the Scroll Wheel on Mouse (or equivalent on Wacom Tablet) to interactively scale the geometry of the edge loop surrounding the point the cursor is over. Each spline point represents a new extrusion. Hitting the ENTER key or the NEW EXTRUDE button, in the Tool Options panel, creates a new extrusion/point. Double-Clicking along the spline creates an intermediate (edgeloop) extrusion/(spline) point, while double-clicking a point removes an (edgeloop) extrusion/(spline) point.

Smart Extrude Extrude face or edge in any direction. Hitting the ENTER key creates a new extrusion. You can also scale (RMB + Drag) and rotate (SHIFT + Drag) selected faces or edges, interactively.

  1. Free Extrude Extrude in any direction. Pay attention that new vertices will not be snapped automatically, but they will snap in further operations if you don't turn off Auto snap.
  1. Normal Extrude Extrude along average normal direction. Pay attention that new vertices will not be snapped automatically, but they will snap in further operations if you don't turn off Auto snap.
  1. Extrude Faces Extrude faces so that each face will be moved on the same distance whenever possible. Pay attention that in some cases exactly parallel faces displacement is impossible but 3DCoat tries to displace as exactly as possible.

Free Moving Moving selected faces/edges/vertices. By using mouse or Gizmo. If nothing is selected entire mesh will be moving. You can move a previously selected group or by pointing with the mouse cursor by pressing the left button. The [Auto pick] option must be activated.

  1. Free Rotating Rotating selected faces/edges/vertices. By using mouse or Gizmo. If nothing is selected entire mesh will be Rotating. You can Rotating the previously selected group or by pointing with the mouse cursor by pressing the left button. The [Auto pick] option must be activated.
  1. Free Scaling Scaling selected faces/edges/vertices. By using mouse or Gizmo. If nothing is selected entire mesh will be Scaling. You can Scaling the previously selected group or by pointing with the mouse cursor by pressing the left button. The [Auto pick] option must be activated.

Primitives: Add simple primitives to scene. Model library of meshs, splines and latheable objects. Use Tool Option Panel to transform model before apply.

Retopo Primitives: This video demonstrates the Primitives Tool in 3DCoat's Retopo Workspace. It helps to create Retopo mesh objects quickly, but can be used as a starting point for poly modeling in 3DCoat, as well.

FreeForm Retopo Primitives: This video demonstrates the usage of Retopo Model presets as FreeForm Deformation Primitives, within the Retopo workspace of 3DCoat, and a tip on modeling interchangeably between the Retopo and Sculpt environment.


Retopo Edge Tools and Selection Tips

Retopo Room Pt.7: Manual Retopo Tools: This video covers some of the Manual Retopology tools in 3D Coat, such as the ADD/SPLIT tool, POINTS & FACES tool, and QUADS tool.

Quick Tip: Using RFill as a Bridge Tool: This video shows how to use the RFill tool in 3DCoat, as a Bridge tool (Bridging two open ended meshes), even though it is designed to Cap ends or openings.
