We are running into weird glitches here...

We have a curtain wall that we need to change a few mullions, glass panels, move doors, etc...

It was originally pinned, but now we "un-pin" anything, change it, and for some reason, when we pin those objects they revert to their previous state. Sort of like doing an Undo. (Didn't happen in 200

Are we missing something here? Or is it a Revit bug?

Are you sure you have a curtain wall? 

REVIT has not done us any favours by their naming convetions of curtain wall and storefront.  Users tend to use those terms interchangably when architecturally they are different and in REVIT they are different.  The REVIT storefront has automatic grid spacing that is pre-defined by the user and you will see that in the types.  The trouble is that users rename these as curtain walls.  REVIT curtain walls have to have grid-lines and elements added. 

REVIT store fronts are hard to edit unless you know what you are doing.  You can delete a gridline today and come back tomorrow and it's back in. 

So what are you using - not what you named it.

Can you put a screenshot with that "Curtain Wall" selected and where we also can see the properties of that?

here are the properties...

you can see two offset panes of glass on the latch side of the door, that is what I'm talking about.  No matter what you do to them, they come back... And can't pin them after correcting anything, cause I'll undo everything....

It is driving me nuts!

I had some storefront in the project, and it almost make me kick this computer with the reappearing grids and unexpected changes... I know it must be the default settings, but it is just not too intuitive.

Thanks guys!

If you see the picture, it has all the curtain wall properties listed in the help file, so I guess it must be a curtain wall and everything is set to "none".  Yet some glass panes get weird offsets and some don't although they are the same type.

Our problem is that REVIT choose to include an automatic storefront/curtain wall system in their package and they call it storefront.  As we all know, storefront systems and curtain wall systems are not the same but in the REVIT world, they use the same components so they are interchangeable - right?  Yes but...  

I think we should correct our terminology.  In REVIT, the differnce out of the box is that the "storefront" is an automatic system.  All of the components and spacings are setup in the wall type.  The other system they call curtain wall is a manual system.  You have to add the grids and components to it.

You have used the automatic system.  So, whever you try to change it, REVIT trys to fix it and make it conform to the type rules you either set up or just accepted by default.

To fix your problem either

1. redo it as a non-automatic system
2. to move grids - tab in elevation to choose the grid line(not the systemm, panel or mullion) - goto the grid properties and switch the type association to independent.  Now you can adjust them.
