I have a wall with an opening in the middle with half-walls on either side of the opening. When I do an elevation view on one side, the lines between the wall and half-wall show, but when I do an elevation view on the other side, they don't - usually. In plan view, the walls are the same width. I tried this configuration in a new plan, and had similar inconsistencies. See the attached pics. I don't want the line between to show as the wall surface should be continuous. Any suggestions? I know I can do photoshop if needed, but wondered if I'm missing a setting or something. I assume the wall construction should be the same for each, as I don't believe I have changed the default.
