The Restyle Workflow
The general workflow for creating a model in Restyle is as follows:
• Open or insert the required facet feature in Creo.
• Click Model > Surface > Restyle to open the Restyle tab.
• Analyze using various surface analyses such as maximum curvature, Gaussian curvature, third derivative, slope, and so on. Use the shaded view to understand the structure of the required surface model.
These analyses can also help you identify:
◦ The analytical surfaces such as planes, cones, cylinders.
◦ The procedural surfaces such as extruded and revolved surfaces.
◦ The significant nonanalytical surfaces, or complex precise surfaces with well-defined boundaries such as aerodynamic surfaces, that you need to create.
◦ Organic shapes where the boundaries of individual surfaces are not of utmost importance.
◦ The parts of the required surface model that you can create using standard Creo features such as rounds.
• Start by constructing the simpler and bigger surfaces that you can use as direction references for more complex procedural surfaces and for surface analyses.
• Create surfaces using the various surface creation tools such as creating curves on facets, from analyses, from intersection with a plane, or 3D curves.
• You can also create a domain on the facet representation. Use this domain to create an analytical surface that is influenced only by the domain.
* 
It is not necessary to create a domain for creating analytical surfaces. You can create analytical surfaces by selecting one or two points. All analytical surface creation tools work with or without the creation of domains, though without a domain the resulting analytical surface may not follow the faceted geometry. Domains can be used for creating partial analytical surfaces like a portion of a cylinder, cone, or a revolution. You can also use domains where an extruded surface needs to be created only at a local area in the model even though the section plane may be intersecting the complete facet model.
• For freeform surfaces, you can also use the Fit Surface to Points and Projection tools. A surface must have a domain or reference points assigned to it in order to fit it.
• If the surfaces have to be intersected with each other, you may need to extend these surfaces. In some cases, it is necessary to re-fit the freeform surfaces after extending them.
• If required, you can assign a domain to an existing surface in order to fit it or to see the deviation diagnostics.

In some cases it is useful to create datum entities using facet representation or other required geometry. You can use datum planes and axes as direction references for analytical surface creation and for analyses. All datum entities (planes, axes, coordinate system, points, curves) created in Restyle use standard Creo user interface for asynchronous datum entities. However, once created, they lose their parametric feature definition and cannot be redefined within the Restyle feature.
• You can align curves or surfaces to make the curves or surfaces position continuous. You can edit or remove the constraints if required for proper modification of individual surfaces and curves.
• You can also automatically create spline surfaces on a facet feature. You can then modify the surface using the existing tools for curves and surfaces.
• You can also create symmetry planes on facet models. The symmetry plane enables you to build and mirror individual halves of a geometry.
• Use the Restyle Analysis tool to dynamically visualize the characteristics of surfaces and curves.
• Use the Restyle Tree tool to display a hierarchical list of the Restyle feature components. Select the required tree components to edit and resolve design issues.
• After completing the Restyle feature, you can use the created geometry for creating regular Creo features.
