# Assembly Editing

Qonic supports hierarchical relations between parts in the form of assemblies. For example, a curtain wall could consist of members and plates, or a staircase could consist of stair flights, slabs and railings. Nested assemblies are also supported; the railing in the aforementioned staircase could in turn consist of some plates and members. To see hierarchical relations between parts, select the parts and open the [Inspect panel](/documentation/qonic-application/querying-and-reporting/inspect-panel.md). In the image below, a stair is selected consisting of 2 stair flights, a slab and a railing, which in turn consists of 13 members and 4 plates.

Qonic comes with some tools to manage these relations: [*Create Assembly*](/documentation/qonic-application/modeling/modifying/assembly-editing/create-assembly.md), [*Dissolve Assemblies*](/documentation/qonic-application/modeling/modifying/assembly-editing/dissolve-assemblies.md), [*Add to Assembly*](/documentation/qonic-application/modeling/modifying/assembly-editing/add-to-assembly.md) and [*Remove from Assemblies*](/documentation/qonic-application/modeling/modifying/assembly-editing/remove-from-assemblies.md).
