How to convert Navisworks (NWD,NWC,NWF) to STL (StereoLithography)?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

Navisworks

Autodesk Navisworks products deliver project review software for 3D coordination, 4D planning, photorealistic visualization, dynamic simulation, and accurate analysis. Create a whole-project model by integrating design and construction information, including complex building information modeling (BIM), Digital Prototyping (DP), and process plant data. With Autodesk Navisworks project review software, you can collaborate, coordinate, and communicate more effectively to reduce problems during design and construction.

Navisworks is a key and core product from which Okino customers often receive and/or coordinate their data files. At Okino we have spent the good part of 2 decades writing our DWF-3D importer specifically to import super-ultra-massive files from Navisworks datasets, such as oil & gas rigs, oil refineries, 3D plants, marine vessils, etc.

Note: you would ideally pre-center the model at the origin and pre-scale the model to be of a "sane size" within Navisworks before exporting the DWF-3D file for Okino software consumption. This will ensure that the model displays properly in your final destination 3D software.

STL

STL (StereoLithography) is one of the industry's oldest (and simplest) 3D file formats created back in 1987 for 3D Systems' first commercial 3D printer. It is widely used for rapid prototyping, 3D printing and CAM. Okino has provided one of the very first and still primary STL export conversion systems for close to 3 decades.

Please take note that there is no 3D file format which is much simpler than STL. It is not a high-end, high fidelity 3D conversion file format as many people have come to wrongly believe. Rather, STL defines just a raw triangulated polygon mesh with no smoothing information (vertex normals), no uv texture coordinates, no assembly hierarchy part naming or any material assignments. 3MF and VRML2 are often much better file formats for moving 3D datasets into downstream programs and/or 3D printers.

The Okino STL exporter WEB page provides good graphical tutorial about how to convert CAD file data into STL and also how to clean a 3D model which is 'almost water tight'.
