Effects of Assembly Structure Editing

When you dissolve a sub-assembly, or reorganize the components at any level, the mates and any features that reference the selected components are affected. Therefore, decisions about hierarchical groupings should be made early in development of a complex assembly, in order to minimize the effects on these items.

  • Mates move to the Mates folder of the lowest common parent.

    For example, assume that there is a mate between P1 and P2, in the Mates folder of the nested sub-assembly S3.

    • If you move P1 up one level (into S1), the mate moves to the Mates folder of S1, the lowest common parent on the same branch.

    • If you move P1 into S2 (a different branch), the mate moves to the Mates folder of the top-level assembly A, because A is the only common parent.

    • If you dissolve S3, the mate moves to the Mates folder of sub-assembly S1.

  • Component patterns have these specific limitations:

    • If you move the seed component of a pattern into a different assembly, the pattern feature and all the instances generated by the pattern are deleted.

    • If you dissolve a sub-assembly that has a component pattern, the pattern feature and pattern instances are deleted. The seed component becomes a component of the assembly at the next higher level.

    • You cannot move individual instances generated by the pattern.

  • Assembly feature cuts and holes are deleted.

  • Equations may not be solved. This is because, in many cases, the instance number suffix <n> of the components changes when you reorganize or dissolve an assembly. This is done automatically, to prevent conflicts with existing components in the destination assembly.

  • The reorganized component is removed from any explode steps where it appears.

  • Routing sub-assemblies are subject to some special rules. See SolidWorks Routing Help for more information.
