    Groups - Fascias Not Updating

    A user is working on a project where they have created groups for dormers, since it repeats around the project. Included in the group are fascias, however they are not consistent between the groups. In the attached file, the group with element id 1156564 & the group with element id 1156228 you can see what I'm talking about. When I try to correct the fascias with the gap on top, it changes the fasicas in the group in another manner. We tried deleting them and replacing them, but that doesn't seem to have worked.

    This happening with other dormer groups in the project, this particular one happens to be the most problematic.

    How were the fascias created? With the Roof/Fascia sweep tool? If so, this could be the problem when used in Groups.

    As a test, for the fascia, try creating a face-based family outside the project, load it into the project and place it on the dormer wall, then Add to Group
    and see if it "survives" better or remains in its correct shape.

    Just a thought, not knowing exactly how things were modeled.

      Yes, they were created with the Fascia tool. I'll try a face-based family.

        When I tried a face-based family I realized that the groups that appeared incorrectly were mirrored from the other instance of the group. When I mirror it back to its original orientation, the fascias (created with the fascia tool) are correct.

          Yes-- mirroring in Groups is a long-standing problem, so we tend to avoid it where possible and make independent elements.

            The good news is you don't have to mirror that group.

              VERY, VERY long standing

                Groups in general and mirroring groups specifically are Revit's Achilles's heel.

                  I mirror groups all day long. Have for years. You just have to know the rules of what can and cannot be in that group, and they work fine.

                    Aaron - Would you be able to point us to a location where we could find out what those rules are?
