Creating Sketch Features
Each sketch line you add to your image is called a feature.
Each feature type uses a different color. Try to make sure that features do not overlap.
Green solid line
Defines the vertical direction of the texture.
Define the Warp and Weft before you define other features. Follow the outside contours of the object. You don't need to draw the full length of the Warp or Weft.
Blue solid line
Defines the horizontal direction of the texture.
Black and yellow dashed line
Defines the visible edges of the surface, where the texture disappears behind the object.
Draw Horizon Edges after you define the Warp and Weft. Draw edges at the edge of the masked area of the object. Draw the entire length of the edges.
Black and white dashed line
Clothing seams, darts, vents, and so on, where the fabric may not line up on either side of the feature line.
Add Cut/Seams after you add edges. Draw the entire length of the cut, seam, dart, or vent.
Yellow solid line
Defines places where the texture folds under itself, and the visible texture may not line up on either side of the feature line. If the texture is obscured by another object, use Hidden Area instead of Fold.
Add Folds and Ridges last. Use either a Fold or a Ridge for peaked areas. Use a Fold if the fabric doesn't line up on either side. You don't need to draw the full length of Ridges or Folds.
Violet solid line
Defines places where the texture peaks along the center of the feature line and levels off around its edges.
Use a Ridge if the fabric lines up on either side.
Black and white dashed loop
Defines the perimeter of areas that are hidden by other objects. This prevents the object from being treated as two separate objects and influences the texture distribution on the visible parts of the object. If the fabric is hidden because the object folds over itself, use Fold instead of Hidden Area.
Use this feature to connect parts of a single object that disappear behind another object. For example, if a blouse is partially obscured by a scarf, define the scarf areas as hidden parts of the blouse.
Continues a texture seamlessly across adjacent objects.
You can add one *Object Connector* feature per object. Solve the underlying object before you solve any connected parts.
When you draw a feature other than Warp and Weft , you draw the feature's centerline. Image Authoring adjusts the area surrounding the centerline in accordance with the type of feature and the current settings.`
