Parametric Modeling End of Life
Beginning with SDS2 2023, Parametric Modeling will no longer be available due to the upgrade to Python 3. You will still be able to create and run Python scripts, members, components and tools. This change will only affect your ability to record parametric scripts within the Parametric Modeling framework.
You will still be able to record scripts in previous versions of SDS2, keeping in mind that those scripts may need to be adjusted for the Python 3 upgrade used in SDS2 2023 and newer versions.
