| Software Suite | Primary Modeling Kernel | Owner / Vendor | B-Rep Representation | Cross-Platform Translation Nuance | Action |
|---|---|---|---|---|---|
| SolidWorks | Parasolid (.x_t, .x_b) | Siemens Digital Industries | Exact analytical & NURBS B-Rep | 100% zero-loss native import into NX & Solid Edge; Parasolid kernel translation is seamless. | |
| Autodesk Inventor | ShapeManager (ASM) | Autodesk (Forked from ACIS 7) | Exact analytical & NURBS B-Rep | Best translated to Revit via SAT/DWG; STEP translation introduces minor edge tolerances. | |
| Siemens NX | Parasolid (.x_t, .x_b) | Siemens Digital Industries | Synchronous technology B-Rep | Native Parasolid exchange without geometric translation stitching or surface healing. | |
| PTC Creo | Granite One | PTC Inc. | Analytical surfaces & procedural | Translates cleanly via STEP AP214/242; imports Parasolid via ATB (Associative Topology Bus). | |
| CATIA V5 / V6 | Convergence Geometric Modeler (CGM) | Dassault Systèmes | Exact topological B-Rep | Direct CATPart import into SolidWorks via 3D Interconnect; high-tolerance stitching required. |

Every input change triggers an instant client-side recalculation across all coupled dependent variables, enabling rapid sensitivity analysis during preliminary and detailed CAD design phases.
Applicable Codes, Standards & CAD Integration
Validate unit system headers ($INSUNITS in DWG/DXF, FILE_SCHEMA in STEP/IFC) and enforce watertight manifold topology before dispatching files to downstream CAM, 3D printing, or BIM coordination.
Engineering Verification Note: Analytical models assume homogeneous material behavior, steady-state boundary loading, and consistent dimensional units. Always apply appropriate service factors, corrosion allowances, or load and resistance factor design (LRFD / ASD) safety margins required by your governing code.
