To create figure 8, I just edited the quantity of holes in the array pattern on the flange. This obviously changes the number of holes on the part, but it also automatically changes the number of pegs in the assembly and constrains them accordingly. Bills of materials and parts lists also update automatically. Patterned parts and assemblies are associative. If you change the number of holes in the flange, the assembly automatically adds and constrains more pegs.
Inventor continues to offer active assembly constraints.
This means that it continuously monitors assembly constraints. If you drag one part with your mouse, the attached parts follow appropriately in real time. As well as the usual positional constraints, such as mate and flush, Inventor now includes two motion constraints. The rotational one is suitable for such items as a pair of gears, and the rotation- translation one for a rack and pinion. Inventor can automatically set the ratio by the diameters of the parts involved.
