How to get rid of areas less then 1800(mm) wide

I made a topic with the same question in the past, but can’t find it.

I made this graph creating a Filled Region over Rooms, If the Rooms are divided by a Wall 100(mm) wide they Filled Region is created from both Rooms. If the Rooms are divided by a thicker Wall it creates two Filled Region. I am stuck getting rid of areas less then 1800(mm) wide.

Do you mean areas less than 1800 Sq.M need to be excluded from the fill regions?

No, see first my image. I need the crossed out Area removed. That is less than 18009mm) wide from wall to wall. I found my old topic. But i need to do that after i got all the Rooms which are divided by a Wall 100(mm) together.

Nevermind. I figured it out with the help of my old topic.

I put this after my last Curve.OffsetMany
