How to convert DWG (AutoCAD, DXF) to OrcaFlex (.yml,sim,.owr)?

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.

DWG

DXF and DWG are the native file formats of the Autodesk AutoCAD product since 1982. DWG is the binary file variation to the ASCII DXF file format. These files can be viewed by many programs including Autodesk's free DWG TrueView application. It is a closed file format but has been documented by the Open Design Alliance.

At Okino we consider DXF/DWG to be one of the worst 3D file formats when translating 3D model data between applications (depending on its contents). There is very little understanding about this in the 3D graphics world. As outlined in our "CAD Data Sourcing Suggestons and Rules" page you should ideally use the DWF-3D file format when sourcing from either AutoCAD, Navisworks, Revit and optionally Autodesk Inventor.

Due to deep history, Autodesk software can embed ACIS SAT "BREP solids" data in some of its DXF/DWG files. This is the ideal case as the "BREP solids" geometry definitions lead to cleaner and higher fidelity MCAD file conversions. But even so, it would generally be a safer bet to use a STEP AP214 or "IGES BREP solids" file in such cases.

OrcaFlex

OrcaFlex is a leading package for the dynamic analysis of offshore marine systems. OrcaFlex is renowned for its breadth of technical capability and user friendliness. OrcaFlex is used by offshore engineering business, with others in seismic, defence, ocean engineering, oceanographic research, aquaculture and related fields.

Converting data from Okino's conversion software into OrcaFlex can best be achieved using the DirectX file format, using Okino's bullet-proof DirectX export conversion system. The Orcina WEB site recommends that the exported models not be too large. If you are converting CAD models then you can set the mesh density on each Okino CAD importer. You can also use Okino's CAD-biased polygon reduction system to reduce the models prior to re-export to DirectX file format.
