Instructions for doing so can be found at the following link: If Civil 3D returns an “Unknown Command” first check to see if the exporter has been installed. This will bring up a save dialog box asking where to save the NWC file. There are a couple of different ways to bring your Civil 3D information in to Navisworks. The process for this is fairly straight forward, as long as the exporter is installed. You can edit these Materials if you want greater control over the Material graph that defines how each surface appears in Unreal, exposing additional parameters to child Material Instances or chase the way these parameters are processed during rendering.There are times for model coordination that an AutoCAD Civil 3D file needs to be brought in to Navisworks. Each of these master Materials is the parent of at least one of the Material Instances found in the Materials folder. Datasmith assigns these Materials to the Static Mesh assets it creates during the import process.ĭatasmith also creates a set of master Materials that can be found in the Materials/Masters folder, one for Translucent Materials and another for Opaque Materials. You can change these exposed parameters to modify the way the Material looks when applied to a surface. These assets are placed in the Material folder next to your Datasmith Scene Asset.Įach asset that is placed in the Materials folder is a Material Instance that exposes properties set in Navisworks. _MyTab_MyStringProperty = "MyStringValue"įor each surface material in your Navisworks scene, Datasmith will create a Material asset in Unreal with the same name. So in the image above, the resulting data would be: The data is prepended with tab names using the following format: This specific point becomes the origin point (0,0,0) inside of UE:ĭatasmith imports metadata stored on objects in Navisworks as Tabs: For this purpose, when using the Datasmith Exporter for Navisworks users can designate the origin point of the scene. This is not compatible with Unreal and can lead to imprecision on import. Setting the OriginĪutodesk Navisworks uses a double precision coordinate system that allows support for models that are very far away from the origin. If the node subtree contains more than 1M triangles, Datasmith merges objects up to a level where the resulting meshes do not exceed 1M triangles. udatasmith file.

See Installing the Datasmith Exporter for Navisworks.Įxport your Navisworks content using the Datasmith Export button added to the toolbar by the plugin. Install the Datasmith Exporter for Navisworks. This means that to get your content into the editor using Datasmith, you need to: Similar to the Revit or 3ds Max Datasmith Exporters, our Navisworks Exporter uses an export workflow. If you are planning to use Datasmith to import scenes from Navisworks into UE, reading this page can help you understand how your scene is translated, and how you can work with the results in Unreal Editor. It follows the basic process outlined in the Datasmith Overview and About the Datasmith Import Process documentation, but adds some special translation behaviors specific to Navisworks. This page describes how Datasmith imports scenes from Autodesk Navisworks into Unreal Engine (UE).
