The Feature Options dialog box allows you to toggle self-intersection checks on and off. Perform self-intersection checks is toggled off by default. In general, self-intersection is possible only when you are creating features with complex geometry, such as loft features (for more information, see What is lofting?, and Self-intersection checks). If you know that your features do not self-intersect or if you plan to remove the self-intersection during a subsequent operation, you can leave Perform self-intersection checks toggled off to speed up feature regeneration. |
