Visit: Downloads Page to download AccuRender nXt for Revit.

You will need to be an administrator to install AccuRender nXt for Revit.

Select and download the file: AccuRender nXt for Revit. Then, unzip the file and run the installation program that it contains.

During the installation, after installing the program files, a dialog will be displayed to help you configure AccuRender nXt for Revit as an Add-In for the version(s) of Revit that you are running.


Simply click on the "Add to..." button for the version(s) of Revit that you are running.

For example. if you are running Revit 2013, click on "Add to Revit 2013". The configure button will then be checked for Revit 2013, and AccuRender nXt for Revit will appear as an Add-In on the Revit Add-In bar the next time that you run Revit 2013.

If you are running Revit 2009 or Revit 2010, click on "Configure Revit 2009 or 2010". You will then be prompted to specify where Revit is installed, by browsing the the Revit.exe file in the Revit folder, so that we can add the necessary lines to the corresponding Revit.ini file for that version.

For example, the Revit.exe file is normally located in “Program Files\Revit Architecture 2009\Program” or “Program Files (x86)\Revit Architecture 2009\Program”. Once you find and select the Revit.exe file and click on "Open", you should get a message box indicating a successful configuration.

After selecting and configuring the version(s) of Revit that you are running, click "Continue" to complete the installation.


  • AccuRender nXt for Revit only works with Revit versions 2009 through 2013.
  • On Vista and Windows 7: Revit will likely need to run as an administrator in order to load its plug-ins. You can do this temporarily, by right-clicking on the Revit icon and selecting “Run as Administrator”. You can also change any Revit shortcut to always run as an administrator by right-clicking on the shortcut, selecting Properties…, going to the Shortcut tab, clicking Advanced, and finally checking Run as Administrator.

Starting nXt

For Revit 2010 through Revit 2013

Revit 2010 addin.png

  1. Open Revit and load a model. An additional menu item, Add-Ins should appear.
  2. Make sure you are not in a Camera or Perspective View*
  3. Select Add-Ins, and the Add-Ins Ribbon should appear, with the External Tools button.
  4. Select nXt From the External Tools drop-down list, and the Control Panel should appear as shown above.
  • Revit Add-Ins can only be activated in non-perpspective views. You can switch back to the perspective view later, after loading the Add-In and the Control Panel. Just leave the Control Panel visible, so that you can render the perspective view.

For Revit 2009

  1. Open Revit and load a model. An additional menu item, nXt should appear.
  2. Load a non-perspective 3D view, so that the nXt menu items are enabled.
    (You can switch back to perspective later.)
  3. From the nXt menu, choose Control Panel.
  • Revit 2009 Add-In Menu items can only be activated in non-perpspective views. You can switch back to the perspective view later, after loading the Control Panel. Just leave the Control Panel visible, so that you can render the perspective view.

Control Panel

The nXt for Revit icons on the Control Panel are:

Revit render.png Render Model, using the current 3D view.
You decide when to Stop the rendering—it will continue refining the picture until you stop it. Try rendering a small to medium sized model first—before you throw something very large at it.

Revit setup.png Load Setup Options Tab Dialog. Set rendering options.

Revit sun.png Load Sun Position Dialog. Set the sun position.

Note: The Sun Position button appears in Revit 2009 and 2010 only. Revit 2011 uses the Revit Sun Settings on the Revit Rendering dialog for the current view.

Revit materials.png Load Materials Dialog. Map a nXt material to a Revit material with the same name.

Revit leaf.png Load Plants Dialog. Map an AccuRender Plant to a Revit family, by family name.

Note: If you wish to render a non-perspective view, select the view while leaving the Control Panel visible.

You can leave the control panel up while selecting different models and views. nXt for Revit will always render the currently active model and view.

Setup Options Tab Dialog

The Setup Options dialog is used for rendering settings in nXt for Revit. Settings are grouped in the following tabs:

  • Presets Tab - Lighting Presets and the settings they affect
  • Render Tab - Render window size, lights per pass, bounces, etc.
  • Lights Tab - Overrides for Lighting Defaults
  • Sky Tab - Sun and Sky modes, colors, and intensity
  • HDRi Tab - HDRi Sky Settings
  • Background Tab - Background Image and Ground Plane settings
  • Foreground Tab - Foreground or Watermark Image settings
  • Image Tab - Automatic Save Image and Image Quality settings
  • More Tab - Other miscellaneous settings

Sun Position Dialog

Revit sun position.png

In Revit 2009 and Revit 2010 and 2010, we are not able to read the Sun position from Revit, so you will have to set the sun again before using nXt for Revit, using our Sun Postition dialog shown here.

In Revit 2011 to 2013, we use the Sun Position from the Revit Sun Settings dialog, accessible from the Revit Rendering dialog, so this Sun Position Dialog is not used.

Materials Dialog


You can create a nXt Material for any of the Revit Materials in your drawing.

Select a Revit Material on the left and Use the tabs on the right to define the nXt Material to match it.

The nXt Material will have the same name as the Revit Material.

The material named nXt_Ground_Plane is the material name used to set the AccuRender nXt material to be used for the ground plane.

Map Materials

  • Advanced - Use the AccuRender nXt Image Editor to create a custom AccuRender nXt material to be mapped to the selected material.
  • Browse - Browse for an AccuRender nXt material to be mapped to the selected material, from a list of pre-defined materials, or from favorites that you have saved as 'User' materials.
  • Groundcover - Define an AccuRender Groundcover to be mapped to the selected material .
  • Load - Load a saved AccuRender nXt material from the disk.
  • Save - Save the current AccuRender nXt material to a file on the disk.

  • Import - Import and re-use the material mappings from another project, where you have already created and mapped AccuRender nXt materials.

Default Tab

Use the Default tab to start with one of these pre-defined materials.

  • Matte - Colored material with a matte finish
  • Glass Thin - Thin should be used for glass created with a single face
  • Glass Thick - Thick should be used for glass with two faces - one for each side.
  • Plastic - low transparency, and somewhat blurry
  • Reflective - medium reflection
  • Metal - highly reflective, with Metallic highlights.
  • Mirror - 100% reflective

See Thin - Thick

Settings on the Glow tab

See: Glow
  • Self Glow - the face glows, but does not illuminate other surfaces. This is the best setting or Neon lights.

Set the glow percentage - 0 to 100%



Select a material from predefined materials, or use "Browse..." in the list tree control to select a texture image from your disk. Use the Parameters tab to set the transparency, reflection and image tile sizes for the new material.

  • Project - AccuRender materials already saved in your project
  • User - Materials you have saved by category as favorites
  • Libraries - Predefined materials based on image files or colors
  • Browse... - Start a new material by selecting an image file from your disk

You will be asked to give the material a category and name, for displaying under Favorites section in the list tree control.

Use the Colorize buttons to select a different color for a texture, either selecting from our list of predefined colors, or by clicking on hte color box to set the actual RGB values for the new color. Reset will reset the material to its original color.
