I downloaded the PVC-U library and i selected this specific Elbow that i want to use but as soon as leave the Routing tab and go back to the assembly the pipe line breaks. I really don't know how i could fix this as this is straight from the PVC-U library and i don't know why it does that, i assume it has to do with the Connection points but i don't know which modifications i have to do.

My objective is to get something like in which the pipes goes straight into the elbow
