How to Scale in Revit: Objects, PDFs, Images, Views & Sheets

Updated October 2026: In Revit, “scale” can mean several different things. You can use the Scale command to resize supported elements, change the View Scale so drawings print correctly on sheets, resize linked PDFs and images, correct CAD import units, adjust fill patterns, or fix print output. The steps below are checked against Autodesk’s Revit 2027 help, with a note wherever an older release looks different.

If you only need the shortcut: select the element, press RE, choose a base point, then use either a numerical scale factor or graphical reference points.

What Scale Means in Revit

Before using any tool, identify what you are trying to scale. Revit does not treat every scale problem the same way, and the wrong method can make a drawing look correct while leaving the model inaccurate.

The short version: if a wall, door, or family needs a real size change, use dimensions and parameters. If a drawing only needs to appear at another scale, change the view scale. Text and tags are sized for the printed sheet, so they follow the view scale too; to make them larger or smaller, edit the text or tag type, not the Scale command.

Revit Scale Command

The Scale command is the fastest way to resize supported elements. It is on the Modify tab and uses the default keyboard shortcut RE. Autodesk documents two workflows: Numerical scaling, where you enter a factor, and Graphical scaling, where three clicks set the origin, the current length, and the new length.

Steps

1. Select the element or elements you want to resize.
2. Go to Modify | [Element] > Modify panel > Scale, or press RE.
3. On the Modify | Scale tab, choose Numerical if you know the factor, or Graphical if you are matching a known distance.
4. Numerical: enter the scale factor, then click the origin. This is the point that stays fixed during the resize.
5. Graphical: click the origin, click a second point to mark the current length, then click a third point or type the correct distance for the new length.

To work out a factor, divide the size you want by the size you have. A 3000 mm line that should be 4500 mm needs a factor of 1.5.

For accurate work, graphical scaling is usually better than dragging by eye. Pick two points on the reference, then type the correct real-world distance. The farther apart your two reference points are, the more accurate the result will be.

Tip: Press Tab to cycle through nearby snap points when Revit is trying to select the wrong reference. Revit also remembers your last Scale settings, so check the mode and factor before you click.

How to Scale an Object in Revit

To scale an object in Revit, select it and use Modify > Scale. According to Autodesk, the Scale tool works on lines, walls, images, links, DWG and DXF imports, reference planes, and the position of dimensions. It does not work on every Revit category, and it does not work on loadable families inside a project.

Three rules decide whether the tool is available:

• Unpin first. Pinned elements cannot be resized.
• Keep the selection in parallel planes. If you select several walls, they must share the same base level.
• Select only supported elements. One unsupported element in the selection is enough to grey out the Scale button.

Walls behave differently from lines. Scaling a wall changes its length, while its thickness stays as the wall type defines it, and doors and windows keep their distance from the wall’s midpoint. If the Scale button is unavailable, change the element through its dimensions, instance properties, type properties, or family parameters instead of forcing a manual scale.

• Use dimensions for walls, grids, levels, rooms, and real BIM geometry.
• Use type or instance parameters for doors, windows, furniture, equipment, and loadable families.
• Use Scale for imported references, lines, images, PDFs, and the other supported elements above.
• Use View Scale when the model is correct but the drawing needs to fit a sheet.

How to Change View Scale in Revit

Changing the View Scale changes how the active view appears on a sheet. It does not resize the actual model. This is the correct method for floor plans, elevations, sections, details, drafting views, and orthographic 3D views that need to plot at a specific drawing scale.

Steps

1. Open the view you want to adjust.
2. Use the View Scale menu on the View Control Bar at the bottom of the drawing area.
3. Select a standard scale, or choose Custom and enter a custom scale value.
4. If the option is greyed out, check whether a view template controls the scale.

View scale also affects annotation appearance, detail visibility, lineweight display, and how the view fits on a sheet. If you need more model detail after changing scale, set the Detail Level to Medium or Fine.

Scale greyed out? A view template may be controlling the view scale. Edit the template, remove the template from the view, or use Temporary View Properties if you only need a temporary override.

How to Change the Scale of a View on a Sheet

A view placed on a sheet keeps the scale of the view itself. There is no separate viewport scale. To change it, select the viewport on the sheet and edit View Scale in the Properties palette, or open the view and change it there. The viewport grows or shrinks on the sheet, so check that it still fits inside the title block.

The Scale label in the title block reads from the views on that sheet. If every view uses the same scale, the label shows that scale. If they differ, it shows “As indicated”. A legend or detail at another scale is a common reason this appears when you did not expect it.

From Revit 2026 you can replace that wording. Select the title block, open Edit Type, and fill in Scale Override (Multiple Values) with your office text, such as “AS NOTED”. The field accepts text only, not numbers.

How to Scale a 3D View in Revit

Orthographic 3D views can use a View Scale. Perspective 3D views do not behave like scaled construction drawings, so you resize their crop region when placing them on sheets.

Steps

1. Open an orthographic 3D view.
2. Click an empty area of the view so the view properties are active.
3. In the Properties palette, change View Scale.
4. Place the 3D view on a sheet and confirm the printed size.

For a perspective view, select the crop boundary, then click Size Crop on the Modify tab. Choose Scale (locked proportions) to make the view larger or smaller without changing what the camera sees. Field of view does the opposite: it stretches the crop to a new size and shows more or less of the scene. Learn more about Revit 3D views.

How to Scale a PDF in Revit

PDFs can be imported or linked into 2D views and used as tracing references. Revit manages them the same way as images, so you can move, copy, rotate, and scale them. If the PDF contains vector data, you can enable snaps and use the linework for more accurate alignment.

Steps

1. Open a 2D view such as a floor plan, ceiling plan, drafting view, or detail view.
2. Go to Insert > Link PDF or Insert > Import PDF, depending on whether you want the file linked or embedded.
3. Select the PDF, choose the correct page and resolution, then place it in the view.
4. Select the PDF and enable snaps if the PDF contains vector linework.
5. Move or align the PDF so one known point matches your Revit model.
6. Press RE for Scale and choose Graphical.
7. Click the first known point, click the second known point on the PDF, then type or pick the correct real-world length.
8. Measure the same distance again to confirm the PDF is now to scale.

You can also select the PDF and adjust its Width, Height, Horizontal Scale, and Vertical Scale values in the Properties palette. Keep Lock Proportions enabled unless you intentionally need to correct a distorted scan.

Note: A password-protected PDF must be unlocked before Revit can import it. For more PDF workflows, see how to use PDF files with Revit.

How to Scale an Image in Revit

Images are often scanned plans, site maps, logos, material references, or presentation graphics. You can import or link an image, then resize it with the Scale command, shape handles, or image instance properties.

Steps

1. Open the 2D view where the image should appear.
2. Go to Insert > Link Image or Insert > Import Image.
3. Select the image and place it in the view.
4. Move the image so one known point lines up with your model.
5. Select the image and press RE.
6. Use Graphical scaling with two known points, or use Numerical scaling if you already know the factor.
7. Check the result with the Measure tool.

If the image is covering model elements, set its draw layer to Background or change the view temporarily to Wireframe while you align it. Learn how to crop images in Revit.

How to Scale a CAD File in Revit

For DWG and DXF files, the best scale fix is usually Import Units or Scale Factor. Scaling the linked CAD file manually can work for a quick reference, but it is not the cleanest method if the CAD file was imported at the wrong unit size.

Steps

1. Go to Insert > Link CAD or Import CAD.
2. Before placing the file, set Import Units correctly. Avoid relying on Auto-Detect if you already know the DWG unit.
3. If the CAD file is already placed, select it and open Type Properties.
4. Adjust Import Units or Scale Factor. When you change the import units, Revit updates the scale factor for you.
5. If those fields are blank, reload the link or re-import the file.
6. Confirm scale with a known dimension, grid spacing, or reference line.

Important: Autodesk notes that SAT and 3DM files cannot be scaled this way. For DWG and DXF files, import units and scale factor are the reliable controls. After a manual resize, the read-only Instance Scale value in the Properties palette shows how far the file is from its original size.

If the CAD file does not appear after linking, check the units, coordinates, and placement option. Large coordinate values or incorrect origin settings can make a linked CAD file appear far away from the Revit model. Learn more about importing CAD files into Revit.

How to Scale a Revit Family

You cannot resize a family with the Scale command inside a project. Families are controlled with dimensions, constraints, type parameters, instance parameters, or by editing the family itself. This keeps the BIM data accurate and avoids broken geometry or incorrect schedules.

Steps

1. Select the family instance.
2. Check the Properties palette for size parameters such as Width, Height, Length, Radius, or Diameter.
3. If the correct parameter does not exist, click Edit Family.
4. Add or edit dimensions and associate them with type or instance parameters.
5. Test the family at multiple sizes inside the Family Editor.
6. Load it back into the project and overwrite the existing version if needed.

If you downloaded a family that has no useful size parameters, the safest long-term fix is to rebuild it with parametric dimensions or choose a better family. Manual workarounds can save time for presentation objects, but they are risky for doors, windows, equipment, casework, or anything that must schedule correctly. If you are new to this, start with reference planes and parameters in the Family Editor.

How to Scale a Hatch Pattern in Revit

Fill patterns in Revit can be either drafting patterns or model patterns. Drafting patterns stay the same size relative to the printed sheet. Model patterns represent real model spacing and scale with the model as the view scale changes.

Steps

1. Select the filled region or material using the pattern.
2. Open Edit Type or the material’s Graphics settings.
3. Choose the foreground or background fill pattern.
4. Edit or create the pattern.
5. For a basic pattern, change the line spacing. For a custom pattern loaded from a PAT file, change the Import scale.
6. Click OK and check the result at the target view scale.

Revit 2027.1 also added a rotate option for custom fill pattern definitions. For the full workflow, see how to use hatch patterns in Revit.

How to Add a Scale Bar in Revit

A scale bar, also called a graphic scale, is an annotation that helps people understand the size of a view on a printed sheet. It is useful for presentation drawings and reduced-size PDF sets where the plotted scale might not be reliable.

1. Open the sheet or view where you want the scale bar.
2. Go to Annotate > Symbol.
3. Click Load Family if the graphic scale family is not already loaded.
4. Choose the correct scale bar annotation family.
5. Place it near the view title or inside your office-standard title block area.
6. Confirm the graphic scale matches the view scale.

How to Print to Scale in Revit

To print to scale, the model should be correct, the view should have the correct View Scale, and the sheet should use the correct title block size. The print or PDF export settings must also use the correct paper size.

Steps

1. Set each view to the correct View Scale.
2. Place the views on a correctly sized title block. Learn how to create title blocks in Revit.
3. Adjust crop regions so the views fit inside the printable area.
4. Go to File > Print or File > Export > PDF.
5. Choose the correct paper size.
6. Avoid Fit to Page when you need an exact printed scale. Use 100% zoom/scale instead.
7. Open the output PDF and measure a known dimension to confirm accuracy.

If a PDF measurement is slightly off after printing, export to PDF directly from Revit when possible and verify that the output is not being scaled by the PDF printer or reader. Autodesk also recommends using 100% zoom/scale instead of fit-to-page when exact output scale matters.

Scale Troubleshooting

Scaling in Revit is simple once you choose the correct method. Use the Scale command for supported elements, images, PDFs, and references. Use View Scale for drawings. Use import units for CAD files. Use family parameters for Revit families. Use 100% print or direct PDF export when the final sheet must measure correctly.

FAQs

What is the Revit scale shortcut?

The default shortcut for the Revit Scale command is RE. You can also access it from the Modify tab after selecting a supported element.

How do I scale a PDF to a known dimension in Revit?

Place the PDF in a 2D view, move one known point into position, press RE, choose Graphical, pick the first known point, pick the second known point on the PDF, then enter the correct real-world distance.

Does changing View Scale resize the model?

No. View Scale changes how the view appears on a sheet. It does not change the real size of walls, families, rooms, or model geometry.

Can you scale a Revit family?

Not with the Scale command inside a project. Revit families are resized with type or instance parameters. If a family has no size parameters, edit the family and add parametric dimensions or use a better-built family.

How do I fix CAD scale in Revit?

Set the correct Import Units when linking or importing the CAD file. For DWG and DXF files already in the model, select the file and use Type Properties to adjust Import Units or Scale Factor.

Why does my title block scale say “As indicated”?

The views on that sheet use different scales, often because of a legend or detail. Set the views to one scale, or in Revit 2026 and newer enter your own wording in the title block type parameter Scale Override (Multiple Values).

Is there a Revit practice file for this tutorial?

Yes. The Revit project file for this lesson is available to Mashyo members on Patreon for $5.5/month, together with the practice files for the other Mashyo tutorials. You can cancel at any time. Open the scale practice file on Patreon.
