Hi All,
Based on a file we received, this is a known error. If the Partial Structural Display is set to 'Core of Load-bearing Elements Only' the opening contours are not displayed correctly. As a workaround, please set the PSD to 'Core only' in combination with possibly putting the non-load-bearing elements on hidden layers. If this is not an option, contours can be drawn on 3d documents.
best, k
