Adding Grids in Revit: Step-by-Step Guide for Beginners

Introduction: Why Grids Matter in Revit

If you’ve ever looked at a set of professional architectural drawings, you’ve probably noticed the lines running across the plans with numbers and letters at the ends. These are grids, and they are one of the most important tools in Revit.

Grids serve as datum elements—guides that help align structural and architectural components. They make drawings easy to read, ensure precision, and improve communication between designers, engineers, and contractors. Without grids, it’s easy for elements to be misaligned or for drawings to feel disorganized.

In this guide, we’ll explore everything you need to know about adding grids in Revit. From creating your first grid line to propagating changes across multiple levels, this tutorial will walk you step by step in a simple, beginner-friendly way.

Step 1: Basics of Grids in Revit

Before we start placing grids, let’s understand what they are.

In Revit, grids are reference lines used mainly in floor plans, elevations, and ceiling plans. They don’t appear in 3D views, but they guide the placement of elements like columns, walls, and beams. Think of them as invisible scaffolding that keeps your design organized.

You can quickly access the grid tool by using the shortcut GR. Or, go to the Architecture or Structure tab and find the grid option in the Datum panel.

Grids can be straight lines, arcs, or multi-segmented lines. The choice depends on the complexity of your project. For most buildings, straight lines are enough, but if you’re working on a curved façade or unusual geometry, arc grids come in handy.

Step 2: Creating Grids in Floor Plans

Now that you know the basics, let’s place your first grid.

Open a floor plan view.
Activate the Grid tool (shortcut: GR).
Click to start drawing your grid line.
Drag it across the floor plan and click again to finish.

As soon as you place a grid, Revit automatically labels it. The software uses numbers (1, 2, 3…) for horizontal grids and letters (A, B, C…) for vertical grids. This numbering system makes it easy to identify intersections, like “Grid B3,” which tells you exactly where to look on a plan.

If you want to rename a grid, simply click on the bubble text and type a new label. Revit will warn you if the name already exists, ensuring you don’t accidentally duplicate labels.

Step 3: Editing and Adjusting Grids

Placing grids is only the beginning. Editing them ensures accuracy and readability.

Aligning Grids: Use the Align tool (AL) to snap grids precisely with walls or reference points.
Adjusting Lengths: Click and drag the end segments to extend or shorten grids as needed.
End Segments & Colors: In properties, you can change grid bubble appearance and color. Many architects prefer grey end segments to keep drawings subtle yet clear.
Bubble Placement: You can display bubbles at the top, bottom, or both ends of a grid, depending on drawing clarity.

If grids overlap or get too close, you can drag one bubble to the side without affecting the grid line. This is useful when multiple bubbles cluster together at the edge of a sheet.

Step 4: Using Breaks and Propagating Grids Across Levels

In multi-story buildings, grids need to remain consistent across all levels. This ensures that what you see on Level 1 matches Level 10.

To do this, Revit offers two key tools:

Breaks (Elbows): When grids are too close to read, you can add a break (elbow). This bends the grid temporarily for clarity, without breaking its alignment.
Propagate Extents: If you adjust a grid in one view, use Propagate Extents (under Modify tab) to apply the same adjustment across other levels. This keeps your drawings consistent.

For example, if you drag a grid bubble outward in the Level 1 plan, Propagate Extents will copy that adjustment to all floor levels.

Step 5: Best Practices for Managing Grids

Grids may look simple, but they play a big role in keeping drawings professional. Here are some best practices:

Plan early. Add grids at the beginning of your project so walls, columns, and beams align properly.
Be systematic. Use numbers in one direction and letters in the other for clarity.
Keep spacing consistent. Irregular spacing can confuse contractors reading your drawings.
Check against structural plans. Coordination between architectural and structural grids avoids misalignment.

By following these rules, you’ll save yourself from confusion later in the project.

Case example for Grids in Revit

Grids are Datum elements used for marking the alignment for the structural elements (columns/structural walls) in a building design.
Grid can be created in floor plans and elevation – Section – ceiling plans views.
Grids cannot be placed in 3d views.
Datum panel which contains Grids can be found in Architectural and structural Tab.

GR is the Shortcut for Placing Grid in plan.
Once grid is selected under Draw panel can find Line, Arc Pick lines and Multi segment. Select Line
Just click on the Floor plan near wall the wall intersection will be highlighted just click and drag straight lines to a draw grids.
Once the grid line creation started it will be 1,2,3.
The change the grid name just click on the text with the bubble and edit the text. If its given A then it will be continued by B,C,D etc.,

When you place the grid the angle option also is shown which allows to set the

Angle of the grid if required.

If the grid is wrongly placed it can be set back to correct position by Align command.

Short form of Align is AL or can select from Modify Tab.

Under Align panel select Center of core.

On click on the grid it gets highlighted and check box appears on the start and end of the grid by selecting the check box the grid name is abled.

On clicking on Edit type of grid can change some parameters of grid.

Edit type – Type properties dialogue box opens.

Color of the end segment can also be changed to grey so it not prominent in the Print out and helps in effective reading of the plan.

End segment length can also be altered because for more complex plan we require more space for placing dimensions.

If center segment is set to None the grid does not pass through the plan even in the section it will not be shown.

Non Plan view symbol if set to top the Bubble will appear only in top.

If Both is selected can see bubble on either end of the grid.

Break helps to add elbow to the grid, when the grid spacing are too close it helps to creating breathing space to identify grid and its name.

Common Mistakes and How to Avoid Them

Beginners often make small mistakes with grids that can cause big issues later:

Misplacing grids. Always use the align tool to avoid inaccuracies.
Overcrowding drawings. Too many grid labels make drawings messy—use breaks and adjust bubbles.
Forgetting propagation. Edits on one level should be propagated to all levels to maintain consistency.
Rotating grids unnecessarily. Grids should stay straight unless the building design requires otherwise.

Avoiding these mistakes helps keep your project clean, professional, and easy to read.

FAQs on Adding Grids in Revit

Can grids be added in 3D views?
No, grids only appear in 2D views like floor plans, elevations, and ceiling plans.

What’s the shortcut for adding grids in Revit?
The shortcut is GR.

How do I rename a grid?
Click on the bubble text and type a new name. Revit prevents duplicates.

Can I control where grid bubbles show?
Yes, you can choose to show bubbles at one end, both ends, or none.

How do I apply grid edits across all levels?
Use the Propagate Extents feature to synchronize changes.

Conclusion: Grids as the Backbone of Revit Design

Grids might seem like simple lines, but they’re much more. They act as the backbone of your Revit model, keeping walls, columns, and beams aligned while making drawings clear and professional.

By learning how to create, edit, and propagate grids, you’re building strong habits that will carry into every project. Whether you’re a student preparing for submission or a professional delivering construction drawings, mastering adding grids in Revit is a must.

So next time you start a project, remember to lay down your grids early. They’ll save you time, reduce errors, and give your drawings the polish they deserve.
