I want to separate all the edge from the default plane. I have the default plane and deleted the faces. With the all edge selected Press the P key and select the by loose Parts. But that did not work to separate all the edge. I have select single edge Press P key and select selection. I have to do this for 3 times for a single plane. Any other way or how can i separate all the edges on to different layers. Any suggestion or help. Thanks.
The following answer works with already extruded walls, but you can do it the same way if you only have edges. And to show different options I've made a more complex shape than a square.
- If you simply want to make all faces separate objects, select them all with A.
- Press Alt+M > Split > Faces by Edges. If you only have edges instead of faces, using V (Rip Vertices) will work, too.
- Now all faces are separated from each other. Press P > Separate > By Loose Parts.
- Now each face is a single object.
If you on the other hand maybe want parts of the wall with more than one face to stay together as an object, you can of course join those objects after you did the above steps. Or you can do it a little differently:
- Alternate selections between faces - for example, select three adjacent faces you want to keep together. Then leave the next face(s) - which should be separated from them - unselected. Select the next one(s) that should be separate, too (sounds more complicated now than it is).
- Hit Y to Split Selection. This way all selected faces get split from unselected faces, while adjacent faces with the same "selection status" are kept together.
- Now press P > Separate > By Loose Parts.
- As a result, the alternating selected and unselected faces are single objects.
Of course, depending on the number of faces and selections you are going to make, maybe with the second method you will have the problem that there are two adjacent faces, both selected or unselected, although to be separated they need to be one selected, the other unselected. In these cases you have to split one of those faces in a second turn of the select/split process.
