Hi,
Just noticed perhaps a bug
I created numerous buildings using the default building parameter [landuse = mixed use]
Subsequently, I changed the default building parameter [landuse to School ]
All my previously defined building also changed their landuse to school...
Cntl Z undid the change to the predefined buildings but still kept the default building parameter landuse as school
Therefore I was able to continue with new default buildings as school... but I am sure the original change to already defined buildings was not intended.
Regards
