About Joining Surfaces

When importing an IGES 3D file, surfaces can be joined into a shell.

You can activate the join in the IGES section of the Preferences.

When this check box is selected, the system tries to knit the surfaces from an importable file into a shell, even if the file contains Groups (402).

Notes:
  • The tolerance value is that of the input file resolution, limited between the modeler resolution and 100 x the modeler resolution.
  • The model must be made of one part.
  • The Join operation may fail in specific topological configurations.
  • This option does not apply to Manifold Solid Brep (IGES type 186): The faces are always imported into a join.
  • When the Import as a Product Structure option is active, the option Join surface of the model is selectable but has no effect.
