In Autodesk Revit, filled regions are currently view-specific, which leads to repeated drafting, inconsistencies, and extra coordination effort when the same graphic is required in multiple views.
This idea proposes a new element type: Model Filled Regions.
Model Filled Regions would behave like standard filled regions (sketch-based, using drafting patterns), but instead of being limited to a single view, they would be visible across multiple views, similar to how model lines differ from detail lines.
Key Features
- Multi-view visibility
A single filled region is visible in all views that intersect its host plane. - Edit anywhere = update everywhere
Changes made in any view update the element globally across all views. - Sketch-based workflow
Created and edited like standard filled regions (no new tools required). - Plane-based hosting
Hosted to:- Levels
- Work planes
- Reference planes
- Optional visibility override
Parameter: “Ignore host level for visibility”
Allows the region to be shown across multiple levels regardless of view range. - Uses drafting fill patterns
Maintains current behavior with view-dependent scaling. - Dedicated category
Controlled via Visibility/Graphics under a new category:
Model Filled Regions - Non-rendering
These elements are purely for documentation and are never visible in rendered views. - Conversion tools
Ability to convert:- Detail Filled Region → Model Filled Region
- Model Filled Region → Detail Filled Region
Problem This Solves
Currently, repeating filled regions across views requires:
- Copying and pasting
- Grouping
- Redrawing
This leads to:
- Inconsistencies between views
- Increased drafting time
- Coordination errors
Why This Fits Revit
This follows an existing and familiar pattern in Revit:
- Detail Lines → Model Lines
- Detail Components → Model Components
- Filled Regions → Model Filled Regions (proposed)
It introduces no new paradigm, only extends existing behavior to improve efficiency.
Summary
Model Filled Regions would provide a simple, lightweight way to create consistent 2D graphics across multiple views, reducing duplication while keeping the flexibility of filled regions.
