Doors disappearing inside curtain walls

[Stoved-In]

Hi There

I have some regular doors placed in a curtain wall. They insert fine but when I try a edit the curtain grid the doors disappear inside the curtain panels. Picture attached should speak for itself...

If I delete the doors and reinsert them it works fine but it's a load of hassle I could do without.

Using Revit Architecture 2012.

Thanks in advance

How are you hosting the doors to the curtain wall? are you using regular walls as your panels? I didn't think doors could cut multiple panels. I'd try breaking the grids at the doors so they stay entirely on their own panel.

Yeh I'm just using a basic wall type I created as the curtain panels. I'm trying to keep my curtain grids as simple as possible as there are some quite complex pattern elsewhere in my model that are giving me a headache. The doors cut multiple panels when you first drop them in, it's only after I tried moving the horizontal gridlines that cross the door opening that this happened.

Thanks
