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.

Codeware Interface Drawing Options

  • General Arrangement

Efficiently create and customize front, side and isometric views of your vessels.  The front and side views include attachment angle, ordinate, length along with height/width dimensions.

  • Heat Exchanger Drawings

Customizable heat exchanger drawings include bundle, channels and tubesheets.  Applicable height, width, thickness and tube layout dimensions are available for automatic application.

  • Custom Flanges (Appendix 2 Designs)

Custom flange detail drawings automatically include the component identifier and dimensions.

  • Nozzle Detail Drawings

Nozzle drawings automatically include details such as WPS notes, weld symbols and dimensions.

  • Drawing options include specifying the drawing order along with specifying component drawing marks for the General Arrangement Drawing.
  • General arrangement drawing layout and dimension options can be enabled/disabled through this dialog.
  • COMPRESS includes the Codeware Interface which automatically generates tube bundle and other detail drawings
  • The automated channels drawing has available dimensions that include Angle, Height/Width, Length and ordinate.
  • Dimensions related to the tube layout along with a Tubesheet Data Table can be enabled/disabled.
  • Automated Saddles drawing include a front, side, and web plate view can be placed with corresponding dimensions.
  • Information like the WPS note, weld symbols, and dimensions can be enabled/disabled.

COMPRESS + CWI = Detailed Solid Models

COMPRESS\CWI created solid models provide the details needed to produce accurate 3D renderings and fabrication drawings.  An example of this is a CWI generated heat exchanger drawing showing a stepped tubesheet:

Nameplates Created Automatically

Every pressure vessel needs a nameplate.  The CWI handles this detail by including a nameplate, as specified in COMPRESS,  in the generated solid model.  This feature also creates a matching nameplate bracket and shows the appropriate nameplate details on the drawing.  Automatic nameplate creation minimizes transcription errors and helps ensure that the nameplate is placed in a convenient location.
