About Quilts
In Creo Parametric, when you create or manipulate nonsolid surfaces, you are working with quilts. A quilt represents a "patchwork" of connected nonsolid surfaces. A quilt may consist of a single surface or a collection of surfaces.
A quilt contains information describing the geometry of all the surfaces that compose a quilt and information on how quilt surfaces are "stitched" (joined or intersected). A part can contain several quilts. You can create or manipulate quilts using a surface feature.
Accessing the Surface Functionality
You can access most surface commands in the Surfaces group on the Model tab.
