Create Drawings Automatically With The Codeware Interface®

The Codeware Interface (CWI) saves designers time and reduces errors by quickly generating SOLIDWORKS® or Inventor®  pressure vessel solid models from COMPRESS and INSPECT designs.  It also includes Drafter 3D, a feature which generates pressure vessel drawings from CWI created solid models.  The CWI is available as an add-in for SOLIDWORKS or Inventor and is supplied at no extra cost to Codeware clients.  It manages the data associated with the imported design files through the use of iProperties (Inventor) or Custom Properties (SOLIDWORKS).  The CWI also supports the use of advanced solid modeling techniques such as Assembly Representations, Configurations, Features, Sketches, Sheet Metal, and Mates.
