To Treat Geometry as Rounds
1. On the Home tab, click the arrow next to Rounds.
2. Click Recognize Rounds. All rounded surfaces in the graphic window are highlighted.
 
• All rounds created in Creo Direct and Creo Parametric are treated as rounds by default. Such rounds or surfaces created by editing tool such as Move or Offset are displayed in green.
• The surfaces not treated (not recognized) as rounds are highlighted in the blue color.
• The following surfaces are displayed in the default model color:
◦ Surfaces that look like rounds but are not created by Round operation.
◦ Round-like surfaces that are imported from Creo Parametric or other CAD systems.
◦ Round-like surfaces, which are created by extruding, revolving, or sweeping arcs and are not recognized or unrecognized as rounds, are highlighted in the assigned model color.
3. Select the rounded surfaces that are not recognized as rounds (blue). An Options Toolbar opens. You can expand the Options Toolbar to open a Floating Dashboard.
 
* You can select only the rounded surfaces that are not recognized as rounds.
4. Click the Recognize Rounds collector and select the rounded surfaces to change the selected rounded surfaces in the graphics window.
5. Middle-click to complete the operation.
