Merge mirrored sheetmetal pieces
I have modeled half of a sheetmetal part. I then selected the part in the model tree and mirrored it. In the options for the mirror I have selected "Merge to model". How do I join these two parts along the seam created by the mirror, on the top surface? I would have thought that "Merge walls" was the tool I needed, but I can't get that to work with any combination of selected surfaces.
