In manufacturing, a unit fitted together from manufactured parts.

A constraint solver is used to calculate the degrees of freedom available for movement, and then minimize the (small) errors resulting from conflicts, if present.Īssembly Hierarchy of components and subcomponents showing relationship within a design, as shown

It is very important to note that, because conditions constrain movement, it is possible to create conditions where a desired movement is not possible. See the printable Assembly constraints reference chart for descriptions of the constraints created between different combinations of geometry. The large cylinder can be moved vertically without moving the small cylinder, but both cylinders move if either is angled because tangency between them must be maintained. In the animated example below, two cylindrical components (one large and one small) are constrained with a tangent condition. These conditions constrain the components so they can't be moved in ways that violate the condition.
