Im trying to find a way to lock to z axis in 3d view.
You can pick your editing plane to be vertical before you create or modify any element, pls check these 3 screenshots from Archicad 25 reference guide they may help.
I prefer using lock to guide command and activate it once you are in the z plan of your movement.
Thanks. I have just realised that when the 3D grid is on there is an z axis guide. I dont usually have the 3d grid on. You are right, its the way to go.
Thanks, Im going to start to do this.
