I was working on semi – automated solution to enter door handiness in Revit models. The existing solutions are either quite expensive (like Reforma Swing Direction) or has weird assumptions.

My intial setup is Dynamo and the Dynamo Door Set Handing module from http://archi-lab.net/. It has fine tutorials, so you only need to create your model in Dynamo.

The weird thing on door handines is it is different in some countries.

  • Door handiness in Germany is defined as hinge position on the door, when one is pulling the door to open. if the hinges are on the left side, the door is left-handed, and if the hinges are on the right side, the door is right-handed. I will refer it ad “DIN – style”.
  • The IFC, together with ISO 16739 defines door handiness as the position of “positive Y axis”, which is definitelly the position of door handle when puling.  I will refer it as “ISO – style”.
  • Americans use ISO style, but also has “reversed” option. I still have no idea on this option, as “reversed right” is “left”.

So, what’s to do?
