Hello. When I export a RAM ELEMENTS SDN, which contains double tee sections of variable inertia, when opened in TEKLA it reads me as W profiles but with the wrong height.

We have not touched the Steel Detailing Neutral file code for many years. Have you tried using iTwin Analytical Synchronizer? I'm not sure if the latest version of Tekla supports integration with ISM, but if so that would be a preferred way to transfer data.
