To change a face's facet accuracy
You can modify the graphic resolution of faces in a similar way to modifying the resolution of entire parts.
To modify the facet model of a face,
1. Click Modeling and then, in the Modify 3D group, click More.
2. Click Face in the Properties section.
3. Select a face in the viewport. The Face Properties dialog box opens.
4. Click Facets.
5. Specify new accuracy values in one of the following ways:
◦ Click a refinement factor (applied to the current values) from the Refine by cascade list. For example, 3 results in three times as many facets in the face; whereas a value of 0.5 results in half as many facets. The Distance and Angle fields are updated to show the calculated tolerance values.
◦ Enter specific values in the Distance and Angle data entry fields.
6. Click Close.
Note that the new values are taken to be the maximum allowable error when refining the faces. The actual accuracy after the refinement may in fact be better for some or all faces.
You also have two options to specify predefined settings:
• Copy - You can copy the facet accuracy of another face. After selecting the face to refine and opening its Facets menu in Face Properties, click Copy from and then specify the face whose values you want to apply. The fields in the menu are updated to show the selected face's values.
• Default - The default Creo Elements/Direct Modeling faceting can be recalled and applied to the selected faces. After selecting the face to refine and opening its Facets menu in Face Properties, click Set to Default. The fields in the menu are cleared to show that the default values have been adopted.
Creo Elements/Direct Modeling uses the given values or refinement factor to change the number of facets on curved faces. A high number of facets results in improved color shading and improved volume calculation accuracy, while low numbers result in improved performance. There are limits on the number of facets Creo Elements/Direct Modeling can use. For example, a complete cylindrical face can have no fewer than 8 facets.
