Unused Parameters

Find project parameters that have no values on any element and unbind the ones you no longer need.

When to use it

Use this after a standards change, a family library swap, or when a model has collected parameters that nobody fills in.

Why it exists

Unused project parameters slow schedules, confuse users in the properties palette, and make shared-parameter audits harder than they need to be.

How to use it

  1. Open Unused Parameters

    On the ✚ Annon App tab, open Purge and choose Unused Parameters.

  2. Search the list

    The tool shows project parameters that currently have no values on any element.

  3. Check parameters to remove

    Select only parameters that should not stay bound to this project.

  4. Purge

    Purging unbinds them from the project. Shared parameter definitions remain in the shared parameter file.

Keep in mind

  • Shared parameter definitions are not deleted from the .txt file - only the project binding is removed.
  • If you still need the parameter, bind it again with Shared Parameters.
