CAD Healing Component

Overview

Today`s multi-CAD world has made translation between CAD, CAM, and CAE systems a common engineering practice. It results in inconsistencies that may prevent the use of some transformation operators and lock further processing of imported digital mockups. Open Cascade CAD Healing Component includes a number of functions to help you to solve inconsistency problems. Healing features include detecting and filling gaps, merging small edges, detection of dirty items and open edges, inverting parts and autohealing.

The CAD Healing Component also contains basic data management algorithms and supports assembly-level operations, such as model loading, saving, restructuring, extracting subassembly to file or retrieving information about data node, recognizing canonical geometry, etc. The Component functionality is available for evaluation with Open Cascade`s end-user product CAD Processor.

Features

• Merging Small Edges into longer ones prevents stability and performance problems.

• Invert Orientation operator first checks whether the part is indeed inverted by sampling a point at infinity. If the point is found to belong to the part in question, then the problem is confirmed, and the operator proceeds to invert the body.



Solid Invertion in CAD Processor




The SDK allows inversion not only for solids but also for shells. The latter is especially important when dealing with CAD parts and assemblies prepared in surface modeling software that doesn’t restrict orientation of shells (such software is popular in the automotive industry). For shells, CAD Healing Component does not perform the membership classification of an infinite point and simply flips the orientation of faces.

• Gap Filling is used to construct a new face on a closed contour in case of missing faces, which may occur due to imperfections in the translator.

• Automatic healing is helpful for healing defects in the model without diving into particular problems. It attempts to fix typical topological imperfections like bad sub-shape orientation or missing seams.
