11. Copyright Theorem Solutions Ltd 2001 1 Create TDP The user creates a STEP file defining the contents of the package This can be exported from a PDM system or using a tool such as PDM AXS The files for the TDP are zipped into a single file (or could be, for example, tarred and compressed in unix) The zip file is connector-mod024.stp Files sent are as follows bolt-m8.stp connector-mod024.stp connector-req.doc frame-connector.stp left-nut-m8.stp left-seatclamp-inner.stp left-seatclamp-outer.stp pict1.gif pict5.gif right-nut-m8.stp right-seatclamp-inner.stp right-seatclamp-outer.stp

13. Copyright Theorem Solutions Ltd 2001 4The supplier logs on to the PDM Exchange@CADverter.com The user uploads the zip file PDM Exchange unzips the file and looks for a STEP file with same root name as the zip file. The file is connector-mod024.stp PDM Exchange processes the file and creates an html representation of the data within the file

14. Copyright Theorem Solutions Ltd 2001 5The supplier accesses the information The user can navigate around the file using the internal references created. The specification for the required work is defined in the file as a managed and versioned document. The user can access any of the files which are referenced in the STEP file and which have a recognizable file format. The user decides which files to translate. If required, the main file with references can be processed as an assembly. Here, the user submits the connector file to CADverter.com and downloads the translated Catia file.

16. Copyright Theorem Solutions Ltd 2001 The new design

17. Copyright Theorem Solutions Ltd 2001 6The supplier uploads the new design to CADverter.com The supplier has to return a STEP file so CADverter.com is used to translate the file into STEP format.

18. Copyright Theorem Solutions Ltd 2001 7The supplier downloads the STEP file

19. Copyright Theorem Solutions Ltd 2001 8The supplier builds the PDM Schema file A new definition is created for just the returned component The supplier adds the technical description to cover the required capabilities of the new component as a managed document. The supplier adds the STEP file for the new component design as an externally referenced geometry file. The supplier also adds a couple of pictures of the new component. This information is created as an XML file and uploaded to The PDM Exchange @ CADverter.com

20. Copyright Theorem Solutions Ltd 2001 9The STEP file is downloaded The new STEP file should be returned to the selected directory with the same root name as the xml file created. PDM AXS will then create a zipped file containing the STEP file and the files referenced in the STEP file as documents. There is an option to encrypt the zipped file. The list of files together with the STEP header information can be created as a comma delimited file and added as input to a spread sheet (or other program). This provides a simple form of transaction logging.

21. Copyright Theorem Solutions Ltd 2001 10 The supplier uploads the new package This can be done direct from within PDM AXS For regular use of a web site, the login address can be configured for easy access within PDM AXS.
