The symbolic lines will not be visible when the family is hosted on a Face or Workplane that is not parallel to the view in which the symbolic lines were added (in the family) => in your model the symbolic lines will only be visible when the family is hosted on a workplane that is NOT parallel to the Level datum.
- However, if the family is hosted on the Level datum, the lines might be hidden by the floor element when the sub-elements of the floor are modified. A possible solution is to host the lines on a reference plane above the Ref. Ebene in the family.
Question: Don’t you need to add a void to cut the floor element? Since this is a drain/drain cover, shouldn't there be an opening (brauchst du kein Durchbruch, oder?)? This might effectively solve the issue of the floor hiding the cover, ensuring the symbolic lines remain visible.
If you need to host the cover on an inclined plane, you might want to use model lines instead. However, keep in mind that model lines will also be visible in 3D. Ideally, such families should be modeled as adaptive, where the 3D object follows the host while the 2D symbolic lines remain parallel to the Level datum (Global Normal).
Another important aspect to consider is the Scheduled Level. I've noticed you changing this arbitrarily. This parameter neither affects where the family is hosted nor its elevation—it only determines how and where the family appears in schedules.
