Not at that stage. One column did end up becoming the basis for a symbol then I replace the others with that symbol. But the 'walls' were never symbols. The strange part is that the different shaped 'columns' were from different parts of the layout process, hours aways from each other. A system reboot with 'Open Current Windows' turned off combined with opening a backup seems to resolve the issue. It's definitely a memory issue whether it's Vectorworks or MacOS hopefully it won't happen too often.
