I am pretty new to blender, trying to cut a mesh in different pieces. I know I can cut a mesh and then separate the mesh using the bisect tool, but I don't want to cut the plane, I want to separate based on a cut I made earlier. I have already made the cut using the cut-through function, but I am a bit lost once I have made the cut.
I want to be able to select one of either sides and separate it in two different meshes, but so far no luck. The picture is seen from above, but I want to select all the vertices left from the drawn line and separate them, thus having 2 different objects.
