Introduction. This is a blog post describing the integration of REVIT and Navisworks and how it can improve the Building Information Modeling workflow integration. Autodesk Revit is a Building Information Modeling (hereinafter BIM) tool for architects, structural engineers, engineers, designers and contractors. It allows users to: Design a built asset and its components in 3D; Annotate a digital model with 2D drafting elements; Access building information from the associated model’s database.
Autodesk Navisworks is used largely as a complement to 3D design packages (including Autodesk Revit, AutoCAD and MicroStation). It allows users to: open and combine 3D models; navigate them in real-time; review the digital model (via comments, redlining, viewpoint, measurement). Generally speaking Autodesk Navisworks 2018 seeks to improve connectivity and interoperability by improving BIM workflow integration, in other words collaboration, including through a focus on its compatibility with Autodesk Revit 2018. This is explored further here.
Capitalizing on Autodesk Navisworks 2018 and Revit 2018 improvements
Here we summarize the essence of the Autodesk Navisworks 2018 and Revit 2018 improvements. 1) Using Navisworks 2018 it’s now possible to: Ensure Navisworks stays up to date with file formats and data types; Integrate Navisworks with Autodesk cloud solutions, other desktop solutions and complementary suites products (including the Revit 2018 underlay feature); Fix blocking bugs and major regression; Open .nwc and .nwd files and import them using model origin or shared coordinates through ‘Coordination Model’ feature. 2) Using Revit 2018 it’s now possible to : Visualize the Revit “coordination model” in either plan, elevation, section or a 3D view; Bring all supported Navisworks formats directly into Revit; Work with the same large datasets in Revit as in Navisworks; Perform the same in Revit as in Navisworks. There are four areas of Navisworks – Revit integration that merit further consideration to understand how together they can improve BIM Workflow integration.
Improved design team integration through a “direct context” workflow.
Revit 2018 “Direct context” workflow can fundamentally change how your design teams integrate, or collaborate, for the better. It provides a “direct context” workflow and large digital models can be used as the context for projects at a scale that was previously impossible. Rather than design teams working independently and then coordinating with others after design production, users are now be able to design and collaborate within the context of the whole project view through what is termed a “direct context” workflow. This is a big step towards a team’s “clash avoidance” target. Design team members can now create coordinated, clash-free data as a seamless part of the design process.
Improved fabrication and detailing capability from a design development phase to through to an onsite installation phase.
Latest Revit updates extend fabrication and detailing capability on its platform from design development through fabrication and coordination to installation onsite. Navisworks 2018 is a key part of this workflow and provides support for new Revit fabrication parts properties.
Improved IFC interoperability through integrated IFC file reader.
Navisworks has a completely new, default, integrated Industry Foundation Class* (IFC) file reader. This leverages the benefits of work already done by Revit to support IFC. The Industry Foundation Classes (IFC) data model sets out to describe the data of a built asset. It is a software agnostic platform neutral, open file format specification. It also has the benefit of parity with Revit by using the same open-source code to handle IFC files. This gives greater consistency for workflows and illustrates Navisworks investment in open-source format. The direct benefits of it include: support for additional IFC property and object types (including IFCSpace and IFCZone); PSets and improved IFC hierarchy handling; more than 80% of IFC bug backlog addressed.
Reduced file size through “optimize on load” function.
Navisworks new “optimize on load” function has a dramatic impact on file size when working with its previous versions. It was reported by one user that a Navisworks 2016 file of 4.7gb was reduced to 200mb using it, saving several minutes each time the model was opened.
