Recently came across an issue with door swings when IFC file is exported from Revit 2019 (188.8.131.52). The doors get mirrored when imported into Archicad or Solibri. This is a big concern as the submission drawings were produced with swing direction against the exit direction. This was due to missing information in Revit. The Door family should have the Operation parameter defined and there is also a specific way to indicate the door swing with lines.
When exported to IFC from Revit, swing door will be picked up from the arc drawn to indicate it as part of the 2D symbol. The arc needs to be created with model line/symbolic line with the sub-category of Plan Swing [projection] (1)/Plan Swing[cut](2). Centre of the arc need to be at the hinge position (3), starting point of the arc should be at the end of the panel when it is fully opened and ending point of the arc should be at the end of the panel when it is fully closed(5).
Next, IFC Parameters/Operation need to be defined in Family Types. It is a text value and a constant in IFC. In this example it is SINGLE_SWING_LEFT. List of operations are given below.
List of Operation:
Hope this helps to solve the door swing issue when exchanging IFC data From Revit. Will catch-up in the next blog soon.
