How to convert Intergraph SmartPlant 3D 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.

Intergraph SmartPlant 3D

Intergraph SmartPlant 3D is Intergraph Process, Power & Marine's next-generation, data-centric, rule-driven solution for streamlining engineering design processes while preserving existing data and making it more usable/re-usable. A member of Intergraph's SmartPlant family of plant modeling software, SmartPlant 3D is a full suite of complementary software that provides all the capabilities needed to design a plant, and then keep it as-built throughout its life cycle.

Files can be exported from SmartPlant 3D as MicroStation DGN files and imported natively into Okino software via our dedicated DGN importer. It is also suggested that you read the related 'Tutorial: How to Import Massive DGN Files (PDMS Plants, Oil Refineries, etc)' section

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'.
