Skeleton Tools is an Autodesk Inventor add-in for multi-body and skeleton-based modeling workflows. Top-down designs are often built as a single multi-body part and then broken out into individual parts and assemblies — Skeleton Tools collects those steps into one-click commands on the Bas Automation ribbon tab. Derive individual part files from the solid bodies of a multi-body part, convert a multi-body part into a full assembly in one step, or explode a multi-body part into its component solids. Commands operate on the active part document and keep associative links back to the source geometry so downstream edits propagate.
