Structure Management on Active Workspace ─ Usage

Pack or unpack structure elements

You can group similar elements in an assembly by packing them together in a single level of the assembly. This results in a shorter and simpler structure display. The packed elements are represented using a single row in the structure with a numeric value appended to this row to indicate the number of packed items.

You can individually pack or unpack the selected elements in the structure that meet the packing criteria. You can also pack or unpack all elements in a selected structure simultaneously with a single click.

When you select a packed node in the tree, all the part instances packed in that node are highlighted in the 3D viewer.

Note

While finding elements within a structure or filtering a structure (Smart Discovery-indexed), the state of the structure remains the same, regardless of whether the structure elements in it are packed or unpacked manually or by default. However, the search results on the Find panel are always displayed as unpacked.

You can specify the reference designator values in the International Organization for Standardization (ISO) and in the American Society of Mechanical Engineers (ASME) formats. In the ASME format, the reference designator value is in the capital letter followed by a number and suffix letter. For example, S1A. In an engineering change notice (ECN), if you modify the reference designator value or quantity for one or more elements in the packed and unpacked mode of a structure, these modifications are highlighted in redlines.
