# Purge Unused **Panel:** Purge Unused | **Menu:** Purge button icon Tools to remove unused graphic styles, patterns, parameters, views and templates from the current model. **Every tool in this menu asks you what to remove before it deletes anything.** None of them runs unattended. What differs is *how* they decide what to offer you. ## Two families of tool **Try-and-delete tools** — Line Styles, Line Patterns, Fill Patterns, Shared Parameters. These attempt to delete each candidate and keep only the deletions Revit accepts; anything still in use is rejected and survives. Each has a plain button that sweeps everything of that kind, and a **By Selection** twin that runs the same sweep restricted to items you pick. **List-and-choose tools** — Filters, Unplaced Legends, Unplaced Schedules, Templates, Unplaced Views. These work out the unused items up front and present that list for you to choose from. There is no By Selection twin because the selection *is* the tool. --- ## Line Styles icon Line Styles By selection icon Line Styles / Line Styles By selection Removes line styles not referenced by any element. The **By Selection** variant lists **every** line style in the model, not just the unused ones — the try-and-delete pass still refuses to remove any that are in use, so a selection that includes used styles is safe, it simply won't remove them. --- ## Fill Patterns icon Fill Patterns By Selection icon Fill Patterns / Fill Patterns By Selection Removes fill patterns not used by any material, surface pattern or element override. Same selection behaviour as line styles. --- ## Line Patterns icon Line Patterns By Selection icon Line Patterns / Line Patterns By Selection Removes line patterns not used by any line style, grid, level or other element. Same selection behaviour as line styles. --- ## Shared Parameters icon Shared Parameters by Selection icon Shared Parameters / Shared Parameters by Selection Removes shared parameter definitions not bound to any category in the project. Same selection behaviour as line styles. --- ## Filters icon Filters Collects view filters not assigned to any view or view template, then asks which of them to purge. --- ## Unplaced Legends icon Unplaced Legends Collects legend views not placed on any sheet, then asks which to purge. --- ## Unplaced Schedules icon Unplaced Schedules Collects schedule views not placed on any sheet, then asks which to purge. --- ## Templates icon Templates Collects view templates not applied to any view, then asks which to purge. --- ## Unplaced Views icon Unplaced Views Collects views not placed on any sheet — floor plans, sections, elevations, 3D views — then asks which to purge. --- ## Notes - Save or back up the model before purging. Deletions cannot be undone once the file is saved. - The list-and-choose tools show nothing to select when there is nothing unused of that kind; they report so and exit. - Running Revit's built-in **Purge Unused** afterwards can free up further items these tools do not target. - These tools cover specific element types. They are not a substitute for a full model audit.
