A Revit key plan is a small diagram on a sheet or title block that shows where the current view sits inside the larger building, floor, campus, or project area. The cleanest workflow for most sheets is to create a Generic Annotation family, draw a simplified plan outline, add filled regions for each zone, and control those zones with instance visibility parameters.
That gives you one reusable key plan symbol. You can place it on sheets, load it into a title block, or nest it in your office title block family, then turn on only the zone that applies to each sheet.
Quick answer: To create a key plan in Revit, go to File > New > Family, open a Generic Annotation template, draw the simplified building outline with lines, add one filled region for each zone, associate each filled region’s Visible property with a Yes/No instance parameter, then load the family into your project or title block.

What Is a Key Plan?
A key plan, sometimes written as keyplan, is a small locator diagram used in drawing sets. It shows the overall project shape and highlights one area, zone, wing, phase, or sheet coverage area.
For example, if a house has a main building, patio, and garage, the key plan can show all three parts in a small simplified outline. On the main house sheet, the main house zone is shaded. On the garage sheet, the garage zone is shaded. The reader immediately understands where the sheet belongs in the overall project.
In Revit, key plans are usually made as one of three things: a generic annotation family, a live floor or area plan placed on sheets, or a title block family with nested key plan symbols. Each method works, but they are best for different situations.
| Method | Best For | Tradeoff |
|---|---|---|
| Generic Annotation | Simple sheet key plans with zones, phases, wings, or matchline areas. | Manual outline updates when the building shape changes. |
| Live Floor or Area Plan | Complex plans that must stay coordinated with live model geometry. | More views to manage and possible sheet scale notes such as “As indicated”. |
| Nested in Title Block | Office standards where every title block should include the same key plan location. | Requires careful instance parameters so each sheet can show the right zone. |
For most architectural sheets, the Generic Annotation method is the most practical. It prints consistently, stays lightweight, and can be controlled per sheet with simple Yes/No parameters.
Before You Create the Key Plan
Do not trace every wall, door, room, or detail from the model. A key plan should be readable at a small size, usually in the title block area or near the sheet view title. The goal is location clarity, not a miniature floor plan.
Before opening the family editor, decide:
- How many zones you need: for example, Zone A, Zone B, Zone C, Garage, Patio, North Wing, South Wing, Phase 1, or Phase 2.
- Where the symbol will live: directly on sheets, inside the title block family, or in a drafting view used for setup.
- Whether the shape is stable: if the building outline changes every week, consider using a live area plan instead of a manually drawn annotation.
- How the zones should read: use simple shaded regions, clean labels, and line weights that still print clearly at the final sheet size.
If your title block is not set up yet, read this guide to title blocks in Revit first. A key plan is much easier to standardize when the sheet title block is already stable.
Step 1: Create a Generic Annotation Family
Start with a Generic Annotation family. This creates a 2D annotation symbol that can be placed on sheets or nested into other families. In Revit 2026, default annotation templates are typically installed under %ALLUSERSPROFILE%\Autodesk\RVT 2026\Family Templates\<language and locale>, but your office may use a custom template location.
- Go to File tab > New > Family.
- Select Generic Annotation.rft or your office’s generic annotation template.
- Click Open.
- Confirm the family category is Generic Annotations from Create > Properties > Family Category and Parameters.
Keep the symbol close to its final printed size. If you draw the key plan extremely large and scale it down later, line weights, filled regions, labels, and minimum line lengths can become harder to manage.
Step 2: Draw the Key Plan Outline
Use simple annotation lines to draw the outer shape of the building or project. You can trace from a printed reference, sketch a simplified version manually, or create a cleaned-up outline from an exported plan. Keep only the information needed to identify the area.
- In the family editor, go to Create tab > Detail panel > Line.
- Choose a thin or medium line style that prints clearly in the title block.
- Draw the overall outline of the project.
- Draw the internal separation lines for each zone or phase.
- Add short text labels only if they remain readable at sheet size.
If you want to understand other 2D symbol workflows, see this guide to annotation symbols in Revit.
Step 3: Add Filled Regions for Zones
Filled regions create the shaded areas that make the active zone easy to see. Add one filled region for each zone, wing, phase, or sheet area you want to control.
- Go to Create tab > Detail panel > Filled Region.
- Use Pick Lines or normal sketch tools to trace the first zone boundary.
- Make sure the sketch is a closed loop.
- Click Finish Edit Mode.
- Repeat the process for every zone that needs to be selectable.
Use a muted fill color or hatch pattern that is strong enough to read but not so dark that it hides the outline. For black-and-white construction documents, a light gray solid fill or a simple drafting pattern is usually safer than a saturated color.
For more control over region graphics, read how to create filled regions and hatch patterns in Revit.
Step 4: Add Visibility Parameters
The important part of this workflow is making each filled region visible or hidden from the sheet. Use Yes/No instance parameters so each placed key plan can show a different zone.
- Select the filled region for the first zone.
- In the Properties palette, find Visible.
- Clear the checkbox if you want the default state to be off.
- Click the small button beside Visible to associate it with a family parameter.
- Click Add Parameter.
- Name the parameter clearly, such as Show Zone A or Key Plan – Garage.
- Set it as an Instance parameter.
- Group it under Graphics or Visibility, depending on your Revit version and office standard.
- Click OK, then choose that parameter for the selected filled region.
Repeat the same process for each zone. If the key plan has three parts, you might create Show Main House, Show Patio, and Show Garage. Because these are instance parameters, every placed key plan can use a different combination.
Common mistake: Do not make the zone parameters type parameters unless every instance of that family type should show the same zone. For sheet-by-sheet control, use instance parameters.
Step 5: Load the Key Plan into Revit
Save the family, then load it where you need it. You can load the key plan directly into the project, or load it into a title block family so it appears as part of the sheet border.
- Click File > Save As > Family.
- Name the family something clear, such as GA_Key Plan_Zones.rfa.
- Click Load into Project.
- Select your project or title block family when Revit asks where to load it.
- If loading into a title block, place the key plan in the correct title block location.
- Save and reload the title block into the project.
If the key plan will be used on many sheet sizes, a strong office workflow is to keep the same Generic Annotation key plan and nest it into each title block size. That way the key plan graphics are managed in one family instead of redrawn in every title block.
Step 6: Show the Correct Zone on Each Sheet
After the key plan is placed, select it on the sheet or title block and use the Properties palette to turn the correct zone on or off.
- Open the sheet where the key plan should appear.
- Select the key plan family or the title block that contains it.
- In Properties, find the zone visibility parameters.
- Check the zone that applies to that sheet.
- Clear zones that should not be highlighted.
- Repeat for the next sheet.
For example, a first-floor partial plan sheet might show Show Zone A, while a garage elevation sheet might show Show Garage. Since the visibility parameters are instance-based, changing one sheet does not change the key plan on every other sheet.
Revit Key Plan Best Practices
Use this checklist before issuing sheets:
- Keep the outline simple enough to read at the printed title block size.
- Use one filled region per zone, not one giant filled region for every condition.
- Name parameters clearly: Show Zone A is easier to manage than Visibility 1.
- Use instance parameters for sheet-by-sheet control.
- Keep the active zone fill visually stronger than inactive outlines.
- Avoid tiny line segments and overly detailed CAD imports.
- Test the key plan on a printed PDF before using it across a full drawing set.
- Update the key plan family when the building outline or phase diagram changes.
If your sheets are split by matchlines, use the same naming logic in the key plan. For example, Area A, Area B, and Area C should match your sheet names, matchline tags, and view references. Consistent names reduce confusion for both the Revit team and the people reading the drawings.
If your key plan represents scope boxes, dependent views, or partial floor plans, connect the terminology to your view naming standard. You can also read scope boxes in Revit and matchlines with view references to coordinate the full sheet workflow.
Generic Annotation vs Live Plan Key Plan
A Generic Annotation key plan is usually best for title blocks and simple zone diagrams. A live plan key plan can be better when the key plan must always reflect model changes, show egress zones, display internal markers, or include information that would be too costly to redraw manually.
| Situation | Recommended Method | Why |
|---|---|---|
| Simple zone locator in title block | Generic Annotation | Lightweight, reusable, and easy to control with instance parameters. |
| Large project with many partial plan sheets | Generic Annotation or nested title block setup | Avoids managing a separate live view for every sheet. |
| Key plan must update from model geometry | Live floor plan or area plan | Model changes can flow into the key plan view. |
| Key plan includes egress, areas, or plan-specific annotations | Live plan or area plan | More flexible for view templates, area boundaries, and coordination graphics. |
There is no single perfect method. The best method is the one that gives the drawing reader a clear locator while staying manageable for the Revit team. If the key plan is only a simple shaded locator, do not overcomplicate it with live views.
Troubleshooting Revit Key Plans
If the key plan does not display correctly after loading it into the project or title block, check these issues first.
| Problem | Likely Cause | Fix |
|---|---|---|
| Key plan does not appear | Generic Annotations category is hidden, or the family was loaded into the wrong place. | Check VG/VV > Annotation Categories > Generic Annotations and confirm the family is placed on the sheet or in the title block. |
| Filled region is missing | The region visibility parameter is off, the fill is white, or another masking region is covering it. | Turn on the zone parameter, test with a dark fill, and check draw order or masking regions. |
| Every sheet changes at once | Zone controls were created as type parameters. | Rebuild the zone controls as instance Yes/No parameters. |
| Key plan is too small or too large | The family was drawn at an awkward size for the sheet. | Resize the family linework and text in the family editor, then reload it. |
| Parameters do not show on the sheet | The key plan is nested in a title block and its parameters were not exposed through the host title block. | Select the nested annotation in the title block family and associate its visibility controls with title block instance parameters. |
If you use Revit LT, be careful with advanced family nesting and visibility controls. Revit LT supports families, but it has limitations compared with full Revit, especially when managing more complex nested family workflows.
Revit Key Plan FAQ
What is a key plan in Revit?
A key plan in Revit is a small locator diagram that shows the overall project and highlights the area shown on the current sheet. It is commonly created as a Generic Annotation family or as a small live plan view.
How do I create a key plan in Revit?
Create a new Generic Annotation family, draw the simplified plan outline, add filled regions for each zone, connect each region’s Visible property to a Yes/No instance parameter, then load the family into your project or title block.
Should a Revit key plan be a generic annotation or a live plan?
Use a Generic Annotation for simple sheet locator diagrams and title block key plans. Use a live floor plan or area plan when the key plan must stay coordinated with model geometry or show more complex plan information.
How do I control key plan zones per sheet?
Create one Yes/No instance visibility parameter for each filled region zone. After placing the key plan on a sheet, select it and check only the zone that should be visible on that sheet.
Why is my Revit key plan filled region not showing?
The filled region may be hidden by its visibility parameter, covered by a masking region, using a white or invisible fill, or placed in a Generic Annotation category hidden by the view. Check the parameter, fill type, draw order, and Visibility/Graphics settings.
Final Thoughts
A good Revit key plan should be simple, readable, and easy to update. For most projects, a Generic Annotation family with filled regions and instance visibility parameters is the best balance between control and speed.
Use a live plan only when the key plan needs model coordination more than sheet simplicity. Otherwise, keep the key plan lightweight, place it in the title block or sheet, and let each sheet control its own highlighted zone.
