How do I know where some lines belong to which shapes

Rsober

Hello,
a friend helped me with building a house model, but he didn't name the shapes and groups and components, and when I received the file I found out that his groups are not very accurate.

after renaming them, I still have 3 items in the outliner:
1- a line: how do I know to which shape?
2 & 3 - show on the outliner but when I choose them nothing is displayed on the screen

thank you,

How the outliner works. Nothing will be displayed on the screen when you select things in the outliner, It only selects (and highlights) objects that are already in the current context and visible layers

You may not be looking in the right direction (zoom extents) or you don't have the right layers visible (Make them all visible).

From the sound of it, your friend only sent you a file where you can see one edge. I doubt it, but if it looks like that, I'd ask your friend--what gives?

You can post the file here.

By logic, if everything is a component or group ("shape" doesn't describe anything) and you have only one edge left, it doesn't belong to anything else.

What is 2 and 3? One problem you might have is if your friend drew anything on other layers. All edges, arcs,cicles etc. should be drawn on Layer0 in fact Layer0 should always be the active layer. You can check this by editing the components and select different edges to see what layer they are on. There's a plugin (should be built-in) called "default layer geometry" which moves all selected geometry (edges faces etc) to Layer0. It's very useful. It leaves components on the layer they are currently on and it operates on geometry both outside and within components (you don't have to edit or "open" the components to make it work). I would usually run it on files I get from others.

you have a line in the Outliner?
