Well, let me juct copy paste a post from AC 21, seems like the same thing happened again.
Graphisoft please give us new bugs, don't repeat the old ones!
Is is just me or the polylines in AC 23 do not work properly with the "adjust" command?
They will extend/adjust only if you want to make them shorter, if you want to extend them to a point further down the line they just stand there, looking, waiting, like it's none of their business.
