Thanks Hans,
for a very clear reply, Split walls at the summit of the eve was the easiest

Geoff

Hi,
I have added a sloping piece of wall on top of an end wall to complete a house eve. I need to adjust its angle and to do that I need to select it. The problem is that the lower base wall is selected each time, how can I differential between the two?

Thanks for all your help,
The plugin AdvancedEdit did the trick

Hi Hans,
Your link just gives me a blank page
Where do I find the AdvancedEdit plugin

Hi,
must have missed something, how do I join two walls at 90° without having to zoom in and ajust them. Is there a snap to the end center point? if you get my meaning?
thanks
