I posted this in the families forum as well, but thought I would try here too:
I have created a wall opening family. It is based on the OOTB Revit door opening family.
There were a few reasons for creating this opening:
1. The brick wrap was not working correctly, so I modified that. This part of the family seems to work fine.
2. The opening tools that come with Revit do not show openings below in a wall. Example: I have a door on the first floor in a structural wall. I would like to use dashed lines on the second floor to indicate there is an opening below.
3. In some instances we require a steel lintel above long openings. Example: Again, I have a long opening on the first floor in a structural wall. I would like to use a heavy solid line on the second floor to indicate the steel lintel above this opening(similar to how framing would be shown in plan).
I would ultimately like to then schedule these openings in a lintel schedule. I believe I can do this with a multi-category schedule.
I created a new reference plane that I placed model lines for both the heavy lintel line and the dashed lines on in the family. This reference plane is set above the opening. I used a dimension and parameter to control the height of this reference plane above the Ref. Level. Ideally I would like this to be the height from the first floor to the second floor. I assumed that because these model lines are locked to this reference plane, they would only show in the model at the elevation of said reference plane. This is true in 3D and elevation, but not plan. For some reason in plan the model lines also show on the first floor where I do not want them.
The second problem with this is that I also assumed that if this reference plane was located somewhere within my view range on the second floor, that the model lines would show up nicely (that's why I wanted to used the floor to floor height from first to second) on my second floor plan. This does not seem to be the case. I actually have to set the reference plane to be at the TOP of the view range or ABOVE it! This does not make sense to me. If something is out of the view range, how can you see it in plan?
I have attached the family. Maybe I blew it and created the family wrong, but any help is greatly appreciated.
EDIT: Just found another new problem - on screen each edge of the opening shows up solid as you would expect, however when plotted, the dashed lines in the family override the solid lines. Very annoying.
