Hey Specklers! 
The 2.20.3 release has some great enhancements for your structural workflows 
. Check out what’s new when working with ETABS:
Enhancements:
-
Grid Systems: Send and receive grid definitions, including rotated grid systems. To or from Revit? To or from Grasshopper? No problemo
- Stiffness Modifiers: Assign stiffness modifiers to 1D and 2D elements in Grasshopper.
- Diaphragms: Create and assign diaphragms to your floor plates directly in Grasshopper.
- End Releases in Revit: Send Revit members with end release information to ETABS and SAP (and yes, these can also be defined in Grasshopper)
Can’t wait? Already available as a 2.20.3-rc prerelease for your testing.
Need some template Grasshopper scripts for the above? We got you!
