Hello, just a quick schedule question. How to include all the windows in the facade that are smaller than - for example 3 m2 and exclude all the openings that are bigger than 3 m2?

A quick answer - via a custom expression-based property:

How to get to that step? I am sorry it is more advanced than what i do withs scheadules.

Create a new window/door expression based property and then add this property criteria to your schedule.

The pre-set and possible custom element properties are essential for creating schedules. Many offices have their custom template files developed which include all needed element properties for scheduling, based on a national or international standard requirements. This way you can (or should) include all necessary element information (example for windows: fire resistance, thermal transmittance, climate class, wind force resistance, air leakage rating, safety class, etc.).

For filtering elements into different dedicated schedules (mostly done on big projects) you can use any property based criteria. The example given in my first post is a simple method of how to identify window openings larger or smaller then 3m2. Based on this expression based property you can add this property into the criteria box and filter out only elements that match the true/false state. For a "false" state criteria you'll have every < 3m2 window opening surface area included in the schedule. You can then make a copy of that schedule and switch this criteria to the "true" state, which will create a schedule of > 3m2 window opening surface area.
