The data base is an Microsoft access database, the best way to edit this is with ‘Access’. Note: to see this you may have to enable hidden files and folders under the windows explorer options. Which Databaseįor the SDNF mapping the database is the GTC mapping.MDB database, this is found under the Advance\data folder of Autodesk within your program files. Using Advance Steel 2021 version and the for the Export to SDNF option via the ribbon, we look at how to make a section group into the Export systems. Also, the entries for the table can be created using the ‘ Autodesk one to one mapping’ or can use the ‘ expression format’ that is common within the database entries. The conclusions of this and approach is explained in the attached document link, but the summary is that for the export process the GTC mapping database, that is located under the Advance folder of Autodesk within your program files, is where you need to look and it is using the table called the ‘Profile Export conversions’, under the Advance Steel type. So, with this goal in mind, we looked into the actual database and more importantly which table and how the entries in the table are completed. The simple answer is that the SDNF export uses the Databases called the GTC mapping, but which one, as there are two locations and then which tables, as there are several within the database. Within Advance Steel there are many different types of Export/import options, the core one of these is the SMLX options for transfer from Advance steel to Revit to Advance Steel, but sometimes over more traditional export formats are needed, in this case the SDNF format (Steel detailing neutral format) was being used to link to a Steel and piping software, the user was using Advance steel to complete their steel process but wishes to update within their piping platform.

So, this is what is behind todays idea for the blog. Recently this question came up from a colleague on how and where you find the Database entries behind the SDNF Export from Advance Steel.
