Coincident Versus Concentric Relationships
A practical geometric study illustrating when axial cylinder concentricity should precede planar face contact mating.
Mating Intent
Constraint Intent & Mating Logic
Mates are not just solver inputs — they record engineering intent. This section covers how geometric relationships should mirror the physical function of each joint.
Expressing Design Intent Through Mates
Choosing coincident, concentric, or width relationships is a decision about how the mechanism must behave. These guides explain the intent behind each choice.

Structuring team standards for mate folder hierarchies, descriptive naming conventions, and pre-release audits.
The One Rotation That Should Remain
How preserving intentional rotational degrees of freedom prevents over-constraining concentric fastener stacks and spherical linkages.
