    The mirror and Flip information is in their properties, if you look with Revit Snoop. The parameters are called FacingFlipped and HandFlipped.

    For whatever reason, you cant access them directly using GetParameterValueByName, as it just returns a null value. But a few people have made nodes that do it for you. And honestly, the Python to do it is simple enough that even i understand it (and i CANT write code). Because it LITERALLY just compares those two possible parameters, to generate the 4 possible outcomes (which, for my needs, is really only two different outcomes).

    So here is a crazy small graph that does it.

    Uses ONE custom node, from Archi-Lab Grimshaw.

    EDIT: To give Credit, Havard Vasshaug did this like... 3 years ago. And introduced me to a new (to me) band (that i now love) while doing it:

    Thanks, I've already tried that node in the same setup you show, but only get null values. I'll see if I can hack the python to just get the flip information out of the door.

    Did you use the Phase Node, or try to use a Code Block to send text in with the correct phase name? The latter doesnt work.

    I used the select phase node. I can get a result if I copy the python script into the result and take out the bit of code relating to to_room.

    I next tried filtering the doors to those in the matching phase and fed them in, and it gives a result. At this point I don't trust the results, since for testing I had a series of doors each with a different combination of flip and mirror. All those doors (having no surrounding room) identified themselves as right or left hand reverse. Right and left hand doors with a to room were either left or right.

    Isn't handing based on the secured side of a door?

    --

    close - where you put the key - http://idighardware.com/2014/08/back...s-handing-101/ - so how does Revit in this workflow determine that?

    Interesting. Well, there are multiple nodes that do it, i think. But that is a good point. I would remove any references to the To Room and From Room all together, as my doors behave really nasty with that stuff, lol.

    Wow! That is confusing. Logically, the secure side and secured side would be the same thing, surely? Take a corridor and a store room off the corridor. To me the corridor is the insecure side, and is where you would need to insert the key. The locked store room is the secure/secured side. Your naming is not how we are used to doing things in the UK, but I discovered a long time ago that how LH/RH is defined varies not only by location (country), but by ironmongery supplier (presumably dependent in which country the company originates). Rather than use LH/RH I always use CW/ACW clockwise opening/anti-clockwise opening direction and then specify hardware as fixed to the opening face or to the closing face as appropriate. That was following guidance from one of the largest hardware suppliers here and I've stuck to that ever since.

    Interesting to see how it varies. How would you determine from which direction you view the swing?

    As to scripting it, the right/left would be determined by based on how the doors are modeled, and then how they have been flipped/mirrored. My intent on the secured side was to combine that information with the location of a shared hardware family.

    I always thought of it as the side from which it was secured - meaning, the side that you would use a key on should you lock the door. The edit I made in the post reflected that clarification based on the website I linked.

    I suspect that the company you're referring to told you CW/ACW to make your life easier but that they still look to see which side is keyed/secured/whatever when they're helping select hardware. You have to know this added bit to choose hardware sets. No getting around it.

    You might find this more trouble than you'd expect. The core of a lockset can be on either side of a door.
