View Full Version : 2016 Elevation at top parameter doesn't match level height

Hello all,

I've run into an issue regarding the Elevation at Top parameter on our floors, it is constrained to level 3 with 0 on offset, the floor is on +154.64 but the elevation at top parameter shows 154300.

The issue arose after we adjusted our model to a new height coordinate system which matches the difference between the two values, but the project basepoint and survey point both shows the correct height coordinates, and measuring down from the floor to a line ive drawn at 0 on the Z axis i get the correct 154.64 value, and switching between pbp and sbp in the level type does nothing.

Exporting the model as an IFC and checking the height there i also get the correct height (using the "include IFCSITE elevation in the site local placement origin" when exporting. and it ends up in the correct location when comparing to the other disciplines models, but when we link them into our revit model theres yet again the difference in heights, their models seem to end up higher than ours. have i somehow managed to just adjust the numbers on the level but not actually moved the building it self or something?

moving the pbp and sbp seem to have no effect on the elevation at top parameter.

I've attached a image showing the issue.

got to admit im fairly lost at this point, so any help is appreciated.

a few quick comments / questions:
Is it just Plan 03 that is affected? Try copy / paste from another level to 03. I assume you have verified Plan 03 elevation.
It's hard to tell, but it looks like there is another solid line in the floor just below Plan 03 level - could this be the .36 difference? Plan 04 floor looks different than Plan 03 floor.
