With version 7, CopyCAD’s ability to repair holes with multiple patches is improved. The software now automatically sketches a new boundary as each part of the hole is filled and so speeds up the repair process. It is also now possible to improve the tolerance within a model having badly-connected triangles, without having to repair all the individual problems first. While CopyCAD has been able to generate triangle models of primitive shapes like spheres, cones and cylinders for several releases and so, for example, add internal features like bosses and ribs to reverse engineered models, this functionality has now been extended to include the generation of extruded primitives from sketched or imported profiles. The creation of split lines that can be used to produce tooling designs from component designs has also been improved in two areas - splitting better along sharp edges, with fewer left-over or badly-connected triangles; the snapping of the split line onto the model has been improved and the curve fitting made more accurate. The triangle-based POL file format used by Polyworks can now be read into CopyCAD. In addition, it is now possible to copy, cut and paste whole models or selected triangles, points, surfaces and curves from CopyCAD directly into Delcam’s PowerSHAPE CAD system.
