# View Templates — Modify **Panel:** View Templates | **Menu:** Modify button icon Tools to propagate filter and category overrides from one view template to many others in the current project. Three of the four tools work **from a source template**. That source selection is the first thing they ask for, and it is easy to miss: > **source template → target templates → what to propagate → apply** --- ## Apply Filter Overrides icon Apply Filter Overrides Copies the graphic overrides of selected view filters from a source template to target templates. **Workflow:** 1. Select the **source view template** — the one whose overrides are correct. 2. Select the **target view templates** to update. 3. Select the **filters** whose overrides you want to propagate. Only filters present in the source template are offered. 4. The overrides are applied. - A filter that does not exist in a target template is **skipped** for that template. - Only the graphic overrides are copied. The filter rules themselves are untouched. **Use when:** You have corrected a filter override in one template and need the same correction in many others. --- ## Add & Apply Filter Overrides icon Add & Apply Filter Overrides Identical to **Apply Filter Overrides**, except that a filter missing from a target template is **added** to it before its overrides are applied. **Use when:** Rolling out a new filter standard, where the filter needs to reach templates that do not yet have it. --- ## Apply Graphic Overrides icon Apply Graphic Overrides Copies **category** overrides and visibility settings from a source template to target templates. **Workflow:** 1. Select the **source view template**. 2. Select the **target view templates**. 3. Select the **categories** to propagate. 4. The settings are applied. **Use when:** Propagating cut patterns, projection line weights or category visibility that are set directly on the template rather than through a filter. --- ## Delete Filters icon Delete Filters Removes filters from view templates. This one has **no source template** — the order is reversed: 1. Select the **filters** to remove. 2. Select the **view templates** to remove them from. The filter definitions remain in the project; only their assignment to the selected templates is removed. Progress is printed per template to the output window. --- ## Notes - These tools act on **view templates**, not on individual views. Views using those templates pick the changes up through the template. - Test on a single target template before applying across a large project — there is no built-in undo beyond Revit's own. - If a tool reports that no filters or categories are available, check the source template actually carries the overrides you expect.
