Hi all and hi @TLiebich
In some country regulations, there are specific technical rules about minimum free pass dimension for Doors and Windows (for example: fire exit regulations, ventilation regulations, habitability regulation, and so on). By now, the current parameters of IfcDoor and IfcWindow of IFC 4.2, are not enought to evaluate these regulations:
- There aren’t direct parameters for ifcdoor or ifcwindow
- To try to calculate these “free pass dimensions” with the current parameters of the IFC 4.2 standard, is really impossible, caused by the variability of the design of doors and windows.
I propose 2 current parameters of the IFC, to implement to IfcDoor and IfcWindow:
- ClearHeight (currently only is for IfcSpace): the ClearHeigt for IfcDoor and IfcWindow, represents the maximum clear height or free height dimension, of an opened door or window (with the main panels/leaf opened).
- ClearWidth (currently only is for IfcRamp): the ClearWidth for IfcDoor and IfcWindow, represents the maximum clear width or free width dimension, of an opened door or window (with the main panels/leaf opened).
Thanks and kind regards,
