Autodesk Revit is a computer-aided design (CAD) software used in building information modeling (BIM). Revit enables architects and civil engineers to generate floor plans, elevations, 3D views, and renderings with great precision and scalability, thanks to built-in intelligent elements such as walls, doors, windows, etc.

If you're still indecisive about the right BIM solution, check out our comparison of Archicad vs Revit to determine which software suits your projects best.

While Revit is certainly useful for streamlining the design and build of any BIM project, it’s also well known for taking a long time to render projects, especially those with large-scale drawings or high-quality settings. That’s because the Revit render engine uses your computer’s central processing unit (CPU) quite intensively.

While Revit is a powerful BIM tool designed for architects and engineers, you might also want to explore how it compares to AutoCAD if you're choosing software for specific design needs.

What are the best computers to run Revit?

You might be tempted to go out and upgrade your current CPU to a multi-core processor with 16 cores/32 threads in order to handle heavy-duty rendering projects. Yet with a price tag of $1,000 and above, this is quite an expensive investment.

Instead, check out our tried-and-true suggestions below to shave precious minutes off your rendering times.

Tip #1: Use “Draft” to Start With

Select “Draft” under the Revit render settings tab before rendering. This will render the image with reduced quality and thus speed up the rendering significantly.

Tip #2: Adjust DPI Settings

It’s really important to consider where your rendered images will be used: Will it be displayed on screen or used for high-quality print?

For projects that require printing, a DPI (dots per inch) of 300 will be necessary, while on-screen models rarely need to be much more than 72 DPI.

When adjusting the DPI settings for a project, keep in mind that the lower the DPI number, the less time your computer will spend rendering the model. Which means a 72-DPI project will render at 4x the speed of a 300-DPI one.

Tip #3: Pick the Right Quality/Size Settings

Select “For screen” instead of “For printer” on the Revit render settings tab. This will make the image of a smaller media, which means fewer pixels of the image. This in turn makes rendering much faster.

Tip #4: Reduce the File Size

Make sure that your Revit files are not too large. Every byte means another second for rendering, so whether your file is 2GB or 10MB will make a great difference in the minutes or hours you spend waiting for the rendering process to complete.

One of the easiest ways to lower the size of your projects is to use Revit’s “Purge Unused” option under the File menu, which allows you to eliminate materials and definitions that aren’t necessary for your project.

Additionally, integrating top Revit plugins into your workflow can help manage file sizes and improve project efficiency.

Tip #5: Unlock Revit’s Full Potential with Vagon

Is your current hardware slowing you down in Revit? It’s time to experience the power of Vagon’s cloud PCs. With Vagon, you can switch to GPU rendering and gain access to 4 x 16GB CUDA activated Nvidia GPUs, turning those boring rendering tasks to a nice and smooth experience.

No need to invest in pricey workstations; with Vagon, you get superior rendering performance right from your existing device within just a few clicks.

If you’re considering upgrading your hardware, take a look at the best GPU for Revit or even the best CPU for Revit, depending on your specific rendering needs. Mac users can also take advantage of Vagon’s cloud PCs to run Autodesk Revit on macOS without any performance issues.

Tip #6: Reduce the Number of Lights

The number of lights on the screen is directly proportional to the rendering time. In scenes with many light sources rendering may slow down. That’s why lights are one of the most contributing factors to rendering times.

In general, an indoor view takes longer to render than an exterior view. An exterior view with no natural light (that is, at nighttime) that shows many interior lights turned on takes an extended time to render.

By turning off artificial lights that are not required for rendered image, you can reduce the number of lights and significantly reduce rendering time. You can use Section box that work for linked files, daylight portals and lights to turn off lighting fixtures, so reducing the number of lights that will impact the rendered image.

Tip #7: Exclude the Scene Backgrounds

Select “No Background” on the Quality tab in Revit. If you exclude a background, the rendered image will appear much faster because the program does not need to process the excess images such as the sky or clouds.

Tip #8: Adjust Render Quality Settings

People usually want a high-quality rendered image and, you may want to change the rendering preferences to a high level. However, high quality rendered images may be slow to generate. So, using higher settings for rendering will require more time to render and may add to your rendering time.

Revit Quality Setting limit options on the rendering dialog such as image precision, reflections, illumination, shadows, light and bounces. Render Quality Settings allow you to specify the best quality for the rendered image. So, for faster rendering process, you might avoid setting these quality settings higher than necessary. For complex projects that require enhanced performance, consider leveraging Autodesk cloud rendering gallery services, which can speed up processing time.

Tip #9: Keep Only the Current View Open While Rendering

Close all view windows while in Revit. These can be seen simply by minimising the current view. Click the close series button at the top right of all views except the one to be rendered.

To further enhance your efficiency in Revit, try using Revit keyboard shortcuts to navigate tasks faster and optimize your workflow.

Frequently Asked Questions (FAQs):

1. What are the best render settings in Revit for faster performance?
   Adjusting settings such as DPI, render quality, and lighting can drastically reduce rendering times. Using "Draft" quality or disabling unnecessary scene elements are quick ways to optimize performance.

2. Is Revit good for rendering?
   Yes, Revit is capable of producing high-quality renders, especially for architectural and BIM projects. However, its rendering engine is CPU-intensive and may require optimization or cloud-based tools like Vagon for faster results.

3. How can I speed up 3D rendering in Revit?
   To speed up 3D rendering in Revit, use draft-quality renders, reduce file size with the “Purge Unused” option, and turn off unnecessary lights or backgrounds. Upgrading your hardware or using cloud-based PCs can also make a significant difference.

4. What hardware is best for Autodesk Revit rendering?
   The best hardware for Autodesk Revit rendering includes a powerful multi-core CPU and a high-performance GPU. For large-scale projects, consider cloud-based solutions like Vagon for enhanced rendering capabilities.
