What CADfix DX is

CADfix DX is a paid Windows and Linux application for translating, repairing, healing, defeaturing, and simplifying CAD models for engineering data exchange and reuse. Automatic and interactive tools can remove short edges, thin or sliver faces, holes, protrusions, fillets, chamfers, and selected features such as ribs. CAD-to-CAE preparation combines geometry repair and simplification with partitioning for planar cuts, general splitting, mid-surface extraction, CFD, and structured hex or swept meshing. The product can morph original CAD geometry to match CAE displacement results, then export it for CAD reuse or CAE remeshing. Reverse engineering converts faceted JT, STL, or CATIA models into CAD BREP models using NURBS and analytic surfaces. Interface matrices cover formats including ACIS, CATIA, Creo, IFC, IGES, Inventor, JT, NX, SolidWorks, STEP, and STL, with availability varying by format. Batch conversion and API access are supported. CADfix DX 14 is listed with build 14.0.0.2/12661.
