Administering structure cloning

Configuring how assemblies in context are cloned and replaced

The Clone Assembly in Context and Replace Assembly with Any Item Type commands are available in Teamcenter MBOM Product or Workarea views when you choose Edit→In Context. How you configure these commands affects how structures are cloned in context within the same MBOM and how items and item types are replaced within in-context assemblies.

Clone Assembly in Context

By default, the Clone Assembly in Context command clones an MBOM subassembly and pastes the clone within the same MBOM. This command:

  • Retains all in-context edits in the cloned subassembly.

  • Lets the MBOM author copy, reference, or exclude in-context attachments from the structure being cloned, and optionally, split occurrence effectivity dates or ranges between the assembly being cloned and the cloned assembly.

Direct and in-context attachments of the new (cloned) line, cloning of children below the new line, and attachments on referenced children below the line added in the context of lines above the new line, are controlled by cloning rules. Cloning rule names are listed in the preference MECopyAssemblyInContextTemplates.

Paste Assembly in Context

This command pastes a copied assembly with in-context edits elsewhere in the same MBOM, creating a new absolute occurrence of the assembly while retaining in-context edits and attachments.

Copied and referenced children are again controlled by cloning rules. Cloning rule names are listed in the preference MEDuplicateAssemblyInContextTemplates.

Replace Assembly with Any Item Type

The Replace Assembly with Any Item Type command replaces an MBOM subassembly item with a new item of a different item type while retaining the original subassembly's in-context edits. The procedure is similar to the File→New item command, but retains in-context edits and also copies, references, or excludes attachments from its original structure.

The Replace Assembly with Any Item Type command always preserves in-context attachments of the new line. Direct attachments of the replaced line, cloning of children below the replaced line, and attachments on children below the replaced line—in the context of lines above the replaced line—are controlled by cloning rules. Cloning rule names are listed in the MEReplaceAssemblyInContextTemplates preference. Properties on the new line can be mapped from properties on the replaced line using the MEReplaceAssemblyInContextAlignProperties preference.
