ℹ️ This function is only available when the project uses the Molio standard.

With a project-wide building part specification (PFBB), you write shared content once and reuse it in other building part specifications. You only write the content that differs.

Derive a building part specification

1. Go to Spec → Manage.
2. Open the context menu on a Molio building part specification and choose Derive.

The original document becomes the PFBB, and a derived copy is created in its place. The copy includes variables and notes, but not the history.

How derived documents work

• Each section in the derived document shows the content of the matching PFBB section.
• If a section is added, renamed or deleted in the PFBB, the change carries through to all derived documents.
• In a derived document, you can't add, delete or rename sections.

Override a section

When a section in a derived specification needs different content from the PFBB:

1. Open the derived specification.
2. Open the context menu on the section and choose Toggle PFBB section override.
3. Write the content for this section.

An icon in the section tree shows which sections are overridden. To return to the PFBB content, choose Toggle PFBB section override again.

Note: A PFBB section can't be deleted while a derived document overrides it, and the PFBB itself can't be deleted until its derived specifications have been deleted.
