Split / Cut An Object From An Object

Box

While you have the component open for editing, Draw a selection box from left to right over the wall that you want to separate. (This should highlight only the parts you need.) Right click and Make Component, being sure to tick the box that says Replace selection with component. Now you have a separate nested component.

Thanks... i've tried that but it's impossible to select all the edges and lines of the wall without selecting the other wall.

The second wall was originally created by pulling out from the other wall.

I have loads of these walls that i now need to separate

It isn't impossible to do it. You can use a selection box to get most or maybe more than you need and then, while holding shift, either add to or subtract from the selection set.

If you've got a large number of these to do it, it may well be more efficient and less time consuming to redraw the walls making them groups or components as you go.

You'll probably find that the bottom face is continuous, you need a line like the one on the top at the corner to separate the walls.

Thanks Dave and thank you box... lesson learned

Suggesting plugins to perform simple actions to people who are learning the rudiments of the program is counterproductive, IMHO.

You maybe right but that was not the "Beginner section"

Box

Pauly's profile says beginner, Pauly's questions says beginner, many people, usually beginners, are not sure where to post. Understanding their skill level is more important than where they put the question. But I might be wrong.

For example, how can i separate these two walls as separate groups easily without having to re-draw
.

Now Slice 2 by Suforyou makes that in 2 clicks! But it's $ !
That can't be more speedy!
Just make your 2 Clicks View Top/Camera Parallel

Thanks guys... this is all really helpful, and much appreciated - thank you.

The slice plugin does not finish the job in this case. If you note the forward group in Pilou's example contains a face belonging to the other wall --see the bounding box (you have to try it to see what actually happens). About the same amount of cleanup required as selecting the wall sections and making a group.

Ah damned betrayed by the technology!
So there is a major bug!
Phone to Suforyou!
