It seems Xsteel CAD files (.nc1) are supported in Autodesk AutoCAD (possibly with a plugin) and as such, it should be possible to convert them to STEP product files (.stp, .step) or other similar formats. Sadly, we haven't found any other relevant information for this conversion or other programs

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned nc1 to stp. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
