A Component That Moves Unexpectedly
Root-cause analysis for loose subcomponents that shift under rebuild commands due to missing rotational anchor references.
Educational Assembly Cases
Educational Mechanical Assembly Cases
Independent walk-throughs of single mechanical assemblies. Each case isolates how mating intent, constraint stacks, and reference choices behave under real diagnostic conditions.
Documented Review Cases
Every case examines one assembly in isolation: which motions the design requires, which mates provide them, and which relationships fail after revision.
Diagnosing an Assembly After Revision
A systematic walk-through for isolating broken mate symbols, missing entity tags, and topological nomenclature shifts.
Understanding Redundant Constraints
Techniques to resolve conflicting assembly mates without weakening the physical definition of mechanical joints.
Interactive Featured Case
The Hinged Arm Assembly
A base bracket, an axis pin, and a pivoting arm examined across three states: correct single-rotation intent, an overconstraining parallel mate, and a dangling reference after boss redesign.
