I tried to merge these two types of lines I have from using the geometric tools "Intersection & Symmetrical difference". They end up being part of the same line and I want to join them together and remain "smart" with their respective attributes. When I try to merge them with the merge vector command I get the "All layers must have the same geometry type" syntax. I'm wondering if there is anyway to get through this and to combine the two vectors into one. I tried to save-as both of the vectors and then combine them that way but when I save-as the symmetrical difference vector then all unwanted vector lines come back. (Look at the second picture to further understand this).
