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

Updated July 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.

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.

• Element scale: changes the actual size of supported model, detail, imported, or linked elements.
• View scale: changes how a view is represented on a sheet without changing the real model size.
• PDF or image scale: resizes a placed reference so it matches a known real-world dimension.
• CAD scale: is usually fixed by import units or scale factor, not by dragging the file larger or smaller.
• Family scale: is normally controlled by family parameters, type dimensions, or editing the family.
• Print scale: is controlled by sheet size, view scale, crop regions, and print/export settings.

This matters because the wrong method can make a drawing look correct while leaving the model inaccurate. If your wall, door, or family needs a real size change, use dimensions and parameters whenever possible. If a drawing simply needs to appear at 1:50, 1/8″ = 1′-0″, or another documentation scale, change the view scale instead.

Revit Scale Command

The Scale command is the fastest way to resize supported elements. It is available from the Modify tab and uses the default keyboard shortcut RE. Autodesk documents two main workflows: Numerical scaling, where you enter a factor, and Graphical scaling, where you define the old and new lengths with reference points.

Steps

1. Select the element or elements you want to resize.
2. Go to Modify | [Element] > Modify panel > Scale, or press RE.
3. Choose Numerical if you know the factor, or Graphical if you are matching a known distance.
4. Pick the base point. This is the point that stays fixed during the resize.
5. Enter the scale factor, or pick the reference points for the graphical scale.

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.

How to Scale an Object in Revit

To scale an object in Revit, select the object and use Modify > Scale. This works for supported elements such as many lines, detail elements, imported files, PDFs, images, and some model elements. It does not work for every Revit category.

If the Scale button is unavailable, your selection contains an unsupported element. In that case, 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, detail work, images, PDFs, and supported geometry.
• 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 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 or viewport 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, place the view on a sheet, select the crop boundary, then use Size Crop. Choose Scale (locked proportions) if you want to make the view larger or smaller without distorting it. 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. In modern Revit versions, PDFs are managed similarly to images. 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.
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.

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

Most Revit families should not be scaled with the Scale command. They should be 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.

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. Change the import scale or spacing value as needed.
6. Click OK and check the result at the target view scale.

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

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?

Most Revit families should be resized with family parameters, not the Scale command. 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.

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.
