Each time you update the assembly, the assembly constraints are enforced.
■ You can make some parts adaptive. Autodesk Inventor allows adaptive
part features to change size, shape, and position based on the applied
assembly constraints.
■ Assembly constraints remove degrees of freedom from components,
positioning them relative to one another. As you modify component
geometry, assembly constraints ensure that the assembly stays together,
following the rules you have applied.
■ The correct application of assembly constraints also permits interference
checking, collision and contact dynamics and analysis, and mass property
calculations. When you apply constraints properly, you can drive the value
of an essential constraint and view the movement of components in the
assembly.
Place Constraints
In Autodesk Inventor, four types of 3D assembly constraints define positional
relationships between components: mate, angle, tangent, and insert. Each
type of constraint has multiple solutions defined by the direction of a vector
normal to the component. The constraint solution is previewed to show the
orientation of the affected components before you apply the constraint.
In addition, motion and transitional constraints simulate intended movement.
■ Motion constraints specify the intended motion between components.
Because they operate only on open degrees of freedom, they do not conflict
with positional constraints, resize adaptive parts, or move grounded
components.
■ A transitional constraint specifies the intended relationship between
(typically) a cylindrical part face and a contiguous set of faces on another
part, such as a cam in a slot. A transitional constraint maintains contact
between the faces as you slide the component along open degrees of
freedom.
Use the Place Constraint dialog box to control the type, solution, and offset
for the constraint.
■ Use the Selection buttons to specify the geometry to be constrained. The
selection buttons are color cued to the corresponding geometry in the
graphics window.
