Manufacturing has gone further and 3D tube cutting is now state of the art. However, Advance Steel doesn't have any solution to export and to process their single parts.
Right now you can only export a .sat, .dwg, . iges, open them in Inventor and convert them to .step. But then all the information is gone, no posNum or Material. So you need to manually add all the needed attributes to the every single part.
For example, a project with 200 m of handrail, you get 700 different parts. Now adding all the different attributes to the parts does take quit a long time. My job isn't sitting several days for adding attributes to single parts.
