How to change height offset from level of multiple ceilings at once?

[35pl4ECJ]

Is there a way to select all ceilings with varying "height offset from level" values and add a value (in this case 2") to all of them at once? I tried just doing = <varies> + 2" but this didn't work.

(I know i can select all in a section/elevation and use the move command to slide them all up 2", im just curious if there's another way to do this using a formula)

What about just moving them all up 2 inches in Elevation View?

What about via a Schedule?

Hi @35pl4ECJ,

Only way to do this with a formula is with global parameters. (which would need to be setup before!)

This would only make sense if they ceilings would have a limited number of different offset.

For those global parameters a offset can be included next to it's height offset from level.

For instance:

Ceiling_offset = 2

Ceiling_height_level_1 = 100 + Ceiling_offset 

Ceiling_height_level_2 = 200 + Ceiling_offset 

Ceiling_height_level_1 and Ceiling_height_level_2 would be connected to the ceiling height.

And with Ceiling_offset they could get a custom offset.

See screenshots below: (I would only use it if they value would be determined in a later stage or changes frequently)

Other bonus when using global parameter, no need to edit groups te value changes across groups

Other 'quick' ways to change it by selecting, if it's a one-time edit:

You already have "<Varies>" value so I assume a selection already has been made?

If selection is made in model itself, just move it in a section/elevation (as you already stated)

If the "<Varies>" refers to a schedule row, select the row and go to a (already open) section/elevation and move them up. (the elements in the Schedule row will be selected in model)

Thank you, this is helpful. For context, I make existing conditions models on revit using 3d scan data, and every now and then we'll see that a floor level wasn't placed as accurately as possible to the scan data at the beginning of a project, (eg. a floor is seen to be far less level than initially thought) and needs to be moved after much of the project has already been modeled & associated to that level. I'm just thinking of the quickest and most efficient ways to resolve these sorta things. 

Thanks again
