There are many reasons why models imported in SOLIDWORKS from IGES, STEP or Parasolid files have topological errors. The various CAD products used for creating geometry "speak" different languages and, in order to understand each other, they need translators. These translators are the neutral formats mentioned before. Whenever you get an extra link in the communication chain, bits of information could be lost and topological errors could be introduced. Examples: gaps in the body, self intersecting faces, faces with more than one closed contour, faces that are piercing the solid body, unsimplified geometry. Once the errors are identified they need to be repaired, otherwise the consequences can be severe: long opening and saving times for assemblies and drawings containing those components, graphics glitches, rebuild errors and even crashes. This presentation will focus on multiple tools and techniques for quickly identifying topological errors and fixing them with minimal effort.
