1- Revit & Robot Public RoadMap https://www.autodesk.com/blogs/aec/ro...

2- Bidirectional transfer of local coordinate systems
Transfer of analytical panels made by extrusion
Transfer of linear and surface loads housed on members and panels
Data transfer of the code types of steel elements (if for example I have EC3 it will be saved for the link – this is for bars not for general models)
Because Revit is the central element for coordinating physical and analytical models, and the geometry of its analytical model can be accurate and completely versatile, the nature of Revit-Robot interoperability has been changed.
The link now provides improved bi-directional transfer of local coordinate systems for analytical elements and panels, resulting in greater consistency between programs.
In addition, the transfer of items that have been split has been improved.
All to better support BIM-centric structural analysis workflows.
We keep the LCS local from Revit to Robot or from Robot to Revit

3- Elements transferred bidirectionally after splitting
The original element has been preserved, we maintain the load ownership even when cutting the analytical beam, in the 2 directions

4- Improving the quality of moment reduction results on walls and linear constraints
Note: This option should be used with caution. The option works correctly when the dimensions of the Finite Elements next to the edge are less than or equal to half of the cross-section of the column/wall. So in my case, the wall is 20 cm thick, so the mesh of the Finished Element should therefore be 20/2 = 10 cm.

There is 2 check box, one for FEM, one for rebar analysis.
for FEM "Reduction of forces above colums and walls"
For Rebar/As "Reduction of forces (at supports or above colums and walls)" before EC2/ACI/Snip/.. analysis

Robot 2025 : Until now, the reduction has only been carried out for the first row of finished elements in the slab - even if several rows (in the case of a very fine mesh) are inside the wall/column

5- Improved Interactive Warning Messages for Loads
We finally have numbers for loads, so it's easier to find, for example, errors in the tables and graphically.
Load Distribution control capabilities have been enhanced to communicate load dependency on structural elements and load conditions.
Additional details have been added to the load description in the calculation messages dialog.
Added an explanation on how to identify the load in tables and views.
The graphical display of the selected load has been improved.
We've exposed the load number in the tables for consistency with the calculation messages.
Detailed information has been provided about the source of the automatically created load.

6- Fire Resistant RC Column Eurocode 2 -1-2 / A1 update
Robot Structural Analysis Professional 2025 includes EN 1992-1-2:2004/A1:2019 and NF EN 1992-1-2/NA/A1 March 2021 for the fire protection design of structural columns with Annex C.
It also offers improvements to the reinforced concrete design listed in the release notes document.

7- USA & Canada Load Combinations
The following standards have been implemented for load combinations
* IBC 2018
* IBC 2021
* ASCE 7-22
* NBCC 2020

8- Steel Bar design ANSI/AISC 360-22
Design of steel bars according to ANSI/AISC 360-22 standard
The following updates have been introduced:
* Calculation formulas
* Seismic calculations
* Required Databases
* User Interface After Standard Updates
The regulation is set as the default in the relevant regional settings (USA).

9- Seismic Analysis ASCE 7-22
The USA regulation ASCE 7-22 is include in two methods Response Spectrum analysis & Equivalent Lateral Force method.
