With Dynamo Extension for Advance Steel 2023 about 40 new nodes were added to complement some of the functionalities added in the last release..
Another important change is that Dynamo Core has moved from Python 2 to Python 3. This comes with a component change as well, from IronPython to CPython. Check your add-ins and scripts for python scripts and upgrade them. Dynamo offers a tool for upgrading each of your Dynamo Python nodes from version 2 to version 3.
The Geometry.GetDistance node was removed because it was duplicating the Dynamo Core node Point.DistanceTo.
