Considerations for Creating an Auto Round Feature
Note the following rules when you create an Auto Round feature:
Convex edges in the model are rounded first. However, edges adjacent to narrow surfaces are not rounded.
Narrow pairs of chains with same convexity are not rounded.
Narrow pairs of chains with different convexity are rounded under different Auto Round members.
Short chains are rounded only if this rounding does not affect the rounding of neighboring chains.
Edges that share a vertex with a chain that cannot be rounded are not rounded, as rounding one of these edges may cause problems in the rounding of other edges.
You can exclude edges from the Auto Round feature by selecting them in the graphics window or in the Troubleshooter dialog box. You can also use the Search tool to select edges to be excluded.
You can exclude edges or a chain of edges from an Auto Round feature. The Auto Round feature does not fail even if the excluded edges disappear from the model due to changes in the model. However, these edges remain excluded if further changes to the model cause the disappeared edges to reappear.
You can select multiple edges chains to be excluded from the Auto Round feature. Edge chains can be regular chains or intent chains.
An Auto Round feature fails if it cannot create any geometry.
You cannot pattern an Auto Round feature.
The Model Player (Tools > Model Player) moves forward and backward through the Auto Round Members, but does not regenerate an Auto Round feature if Regenerate features is not selected. However, if you select Regenerate features, the Model Player regenerates the Auto Round feature but does not move forward or backward through the ARMs.
