SMLib Kernel Fillets

Use this skill when edge blends, chamfers, variable-radius fillets, fillet removal, previews, or local blend topology fail or produce invalid geometry.

Purpose

Diagnose and change fillet/chamfer/blend behavior from Python and SM_API through SmFilletExecutive, solver selection, corner handling, topology insertion, and post-processing.

Prerequisites

• Know the target edges or vertices and verify they come from the live Brep being mutated.
• Record radius, cross-section, continuity, and nearby face sizes before kernel debugging.
• Use usd-brep-test-selection for focused fillet and local operation validation.
