Slab Gap Revit 2026



Hello, I have tried to erase these gaps (yellow), but on the latest version of Pollination I can’t find the room manager where you can change the limits (I can only change the properties). Besides, if I try to use extrusion height I solve the gaps but also change the height of some spaces (purple) that must be shorter than other rooms of the same floor. How can I get rid of the gaps without effecting the other rooms, thanks.

Hi @danserr,

Did you set up the extrusion height in step 2? See here:

Hi @mostapha, thanks for the answer, I found the option of Override/Reset Height and changed it for the rooms I needed it. However, is there a way to avoid this manual process on more complex models?

Hi @danserr,

Between setting up the extrusion height for every level and overwriting the values for the rooms you should be able to resolve almost every model. Do you have an example of the model that you consider more complex? Possibly, there are ways to automate this, but I can provide more useful feedback if you can share a sample model with me.
