How to Configure a Specific DWF Export Setting in Revit

Published in Revit Export Configuration 3 mins read

You can configure a specific DWF export performance setting in Revit by editing the Revit.ini configuration file. This allows you to define the number of worker threads used during DWF export.

Understanding Export Configuration

While Revit offers various ways to define reusable export setups through its user interface for formats like DWG, PDF, etc., some specific performance or backend settings are controlled via configuration files. The provided steps detail how to adjust one such setting related to DWF exports by directly modifying the Revit.ini file.

This particular setting, ExportDwfNumberOfWorkers, allows you to specify how many background processes Revit should use when exporting to DWF format. Adjusting this value can potentially impact the performance of DWF exports.

Steps to Configure DWF Export Workers

To configure the ExportDwfNumberOfWorkers setting, you need to locate and edit the Revit configuration file.

Here are the steps based on the provided reference:

  1. Navigate to the folder below: Find the installation or user data folder where your Revit.ini file is located. The exact path can vary depending on your Revit version and operating system.
  2. Open up the file named "Revit.ini": Use a text editor (like Notepad) to open this configuration file.
  3. In the file, locate the [Export] section: Scroll through the file to find the section header [Export]. If this section does not exist, you may need to add it.
  4. Under [Export], define the setting "ExportDwfNumberOfWorkers" as your desired number: Add the line ExportDwfNumberOfWorkers= followed by the number of worker threads you want Revit to use. For example:
    [Export]
ExportDwfNumberOfWorkers=7

    Replace 7 with your desired number of worker threads.

  5. Save changes to Revit.ini: Save the modifications you made to the Revit.ini file.
  6. Restart Revit: Close and reopen Revit for the changes to take effect.

Example Configuration

Below is an example snippet showing what the relevant part of your Revit.ini file might look like after adding this setting:

[Export]
ExportDwfNumberOfWorkers=4
; Other export settings might be listed here...

Note: The semicolon ; indicates a comment line in the .ini file.

Why Configure Export Workers?

Adjusting the number of DWF export workers can influence how quickly DWF files are generated, particularly on multi-core processors. Increasing the number of workers might speed up the export process by utilizing more CPU cores, but setting it too high could potentially consume excessive system resources. Finding an optimal number often requires testing on your specific hardware.
