Patches Between the Guides

Panel: Sidebar ‣ QuadGuide ‣ Options ‣ Fill with Patches

With Fill with Patches on, every region the guides close off is filled as its own patch of quads, with the guides as its exact borders.

Left: a box drawn as a network in Draw, every region tinted with a grid sketched in each. Right: the box remeshed, each face one grid and the round port a circle in a square

Fill with Patches

Off On
Fill with Patches off: the quads flow along the lines, the port has a pole Fill with Patches on: every face one grid, the port a circle in a square

Off (the default), the guides steer the flow. On, each region is filled as drawn.

The Tint

With Fill with Patches on, Draw tints each region: one that can be one patch (a closed outline with three to eight corners) gets a color. A blue-gray region is filled freely; if it should be a patch, it is usually open somewhere: glue the loose end (see Junctions).

To choose how a region is filled (grid or free), hold K and click it; see A Region's Kind.

Fixing the Drawing

The panel lists what keeps the drawing from filling, with a button for each fix, and Fix All.

N loose ends ‣ Connect
Runs each loose end on to the next guide.
N loops cut in two by a line ‣ Free
Stops the line just short of the loop.
N places where lines nearly touch ‣ Part
Moves one line apart from the other.
N regions need a line
Draw a guide across the region, corner to corner.

Reading the Result

"except N region(s) remeshed freely"
A region is too big for its outline. Draw lines across it.
"above the N asked"
The outlines need more quads than Quads asks. Draw fewer lines.
"your patches were not used ... marked red"
A patch folded at the red mark, usually two guides too close or a corner far from square. Move a guide and remesh.

Notes at the bottom of the panel lists what the engine changed, with a button to jump to each place.
