CAD Import Options

•     Healing: This option controls the healing of topological data during the translation process. Set this option to true to enable healing. This can be applicable on both the source as well as the target components during the translation. The input file for translation might contain bad data, which means that the translated target file might possibly contain corrupted information. In addition, the geometrical or topological errors might occur during the translation process. To ensure precise and valid translation, connect provides this option for repairing and healing the translated files. Repairing involves checking the translated file for corrupted data and fixing the invalid data. Healing corrects the differences in precision between source and the target entities

•    Operations Performed: The repairing process can be categorized as follows:

o  Tolerizing of Target Entities (edges and vertices): Tolerance (precision) of the source entity might be coarser than the target kernel tolerance. This usually results in tolerance-related errors. Edges which perfectly connect at ends in the source system might show gaps in the target, or the vertices that lie on faces may give gap errors. To repair this error, tolerizing is performed on the entities. An appropriate tolerance is computed and applied to every edge and vertex of the body.

o  Healing of Entities: Healing of entities can be categorized into three types:

-   Modification of topology of body: This process involves the removal of duplicate and overlapping vertices, removal of small edges, removal of sliver faces from the body, and splitting of edges having large G1 discontinuities in their curves. If the target system is Parasolid, then this involves removal of small edges, and removal of sliver faces from the body.

-   Modification of geometry of body: This involves reconstruction of self-intersecting and irregular curve geometry of edges, co-edges, and surface geometry of faces, as well as the trimming and sub-setting of underlying surfaces of faces to a uv-box of a face. If the target system is Parasolid, then Translator does not modify the geometry of the body under this option; however, the Deep Healing option does.

-   Fixing of other invalid data in the body such as loop errors.

•     Translate Free Curves: This option controls the translation of free curves and wire bodies. Set this option to true to enable the translation of free curve data and wire bodies in the destination format.

•     Translate Free Surfaces: This option controls the translation of free surface data. Set this option to true to indicate that Translator is to read and translate free surface data.

•     Translate Solid As Sheets: This option controls whether to export a solid body as a sheet body. Set this option to true to enable translation of a solid body as a sheet body in the destination file format.

•     Convert Free Point To Marker: This option controls the translation of free point data and convert to the Marker. Set this option to true that the Translator is to read and translate free point data and create the Marker at that position.

•     Assembly Option (CATIA)

•    Divide to each Body: This option is the default option in previous versions.

•    Merge To Single Body: If this option is selected, the multiple imported bodies from one CATPart file or CATProduct file are automatically merged into one body.

•    Preserve Assembly Structure: If this option is selected, the assembly structure defined in the file is preserved. (only for CATProduct file)

•     Solid Import Option (STEP)

•    No Trim and Stitching: This option is the default. If this option is selected, Trim and Stitching option does not work.

•    Trim and Stitching: If this option is selected, solids are read as trim and stitching is performed.
