lights scheduling in groups problem

[RevitGary]

I have lights in groups. On the main floor quantities are scheduling fine.
20 type LT-A lights, 30 type LT-B lights etc
I am counting type marks within in the light family

The groups are copied to many floors. On upper floors the light schedule count is hit or miss.
They do not count properly. If I "select all instances" in the view it is the correct number that should be in the schedule.
I can see them all. If I try to "tag all" the lights that are not showing up in the schedule will not get a tag.

Any thoughts?

Phases? Filters? Design Options? Open / Closed Worksets? What's the building total looking like? If that's right but the levels are wrong then there's a problem with associated levels and offsets.

[RevitGary]

No phases
Filter is level equal, type mark contains
No design options
All worksets are open
Building totals seem to be fine

What would the problem be with associated levels and offsets that would cause this?
if I am in the rcp and "select all instance in visible view" the count is correct.

thanks

To be sure that missing matches to your filter on Type Mark is not the problem, make a copy of the schedule without the filter but with sorting rules instead. I hate Filters on Schedules, dangerous stuff, so I always have a QA copy with no filters.

Otherwise it sounds like you have some lights associated with a different Level than the Plan View in which you are seeing them (via select all in view). How is the Family constructed? If it's face based and put on a wall, some of them could have moved up to the next Level but still associated with the level in which they initially were placed.

I'm not 100% sure that's possible, but I'm pretty sure I've seen it happen with Families built in certain ways, especially face based.

How do you make a schedule without filters?
I have a schedule set up with no filters for working reference.

The filter is by level then by type mark
The sorting group is type mark.

The lights are face based families connected to the ceilings

I am pretty sure this is a group issue.
Everything was probably fine in the beginning then it slowly got screwed up.
Due to editing of the lights and ceiling.

So in your schedule without filters, if you group by Level, are there some instances which schedule on a different level than the level you find them on?

Groups in Revit are a gift from the devil, I don't use them, they create all sorts of problems if users are not very very careful, all of which are too time consuming to fix.

What happens on a level where the scheduled number is wrong if you break up all the groups and their subgroups on that level?

[RevitGary]

I am not currently at work so I cant look at things.

How would you do a multistory building without groups?

[RevitGary]

Many lights are not scheduled on any level at all. They are there if Isolate them and look at them, they are in a group on the correct level. In the schedule the group column is blank and it lists all the lights that don't seem to be associate with any level. Any ideas how to fix this?

[RevitGary]

I have been experimenting. Nothing has worked.
The good group is level 3. I deleted the group on level 5. I copied level 3 to level 5. Nothing changed.
I created a reference plane on level 3 and attached lights to it. Then copied it to level 5.No luck there either.
Instead of coping I tried placing the group . No luck.
anyone have any ideas?
