Archicad Grasshopper Live Connection - Port Number can't be changed.

Aaron Bourgoin

I have the connection installed on AC25, but I'm doing a bunch of work in Archicad 24 sessions. 


It appears that unless my AC25 is the first AC started, it latches onto another art that Grasshopper can't see and, contrary to what the manual says, I cannot change the port number inside Archicad or Grasshopper. 


If that's true, can we please have access to the port number setting restored?

@Aaron Bourgoin i agree with you. i have also noticed that when i'm running several AC25. While rhino grasshopper is somehow locked into one port while AC25 will have different ports since the other AC25 that was opened earlier is locked onto that one port.

The only work around i did was if i planned to use grasshopper i would close all AC25 and open a new one to match the port of which rhino grasshopper is locked in.

Hopefully the devs can resolve this. 😎

In the end what is your Objective?
ArchiCAD 9 onwards


I'm having the exact same problem and frankly I cannot understand how this issue is still present. When can we expect this to be fixed? AC39?


yeah, not sure if they over look this. 😆
