Hello everybody!!! I am trying to place an electrical fixture, face based next to a door. Unfortunately the OOTB familyinstance node is giving an error and the spring node “FamilyInstance.ByFaceAndPoint” is outputing a null value. I would appreciate your help!!!
Ps: The original graph was created here

Hello sovitek,
First I want to thank you for your amazing script. It helps a lot.
Second, after trying out your script on my project it wont work. Tried to look for a solution but as i’m a newbie and don’t understand a lot with Geometry in Dynamo I couldn’t figure it out.
Could you please help me? Thank you
Hello @cesar …could you upload your graph what you already had tried and i will take a look;)
I haven’t touched the graph much, but from what I see in the 3D preview is that the script doesn’t pick the wall as reference so the node Geometry.DoesIntersect gives an empty list as output.
Try to stay in planview when run, because i use doors symbolic lines in that case, for find side and swing…
Could the reason be that I use custom doors family instead of default revit ones?
probably…could you share a little snap of the rvt you working on
Sure, here is a wetransfer link (500mb) with the electrical fixtures rvt and the architecture rvt as revit link
500 mb ! did you purge the files before upload ? but thanks i take a look later today…
Sorry forgot about that, I changed the link with a smaller size files on my previous post.
Thank you
Hello…find a very old one here, but could work on your model…good luck

Hello, may I ask you what version Dynamo for Revit you are using, and if the packages are up to date cause for me it still won’t work. Geometry intersiction gets me an empty list everytime. I am using Dynamo 2.12 Core and Revit and for the packages first i installed older vesions used in your script at that time and then installed the latest version, same result
Yes exactly as in your video from your youtube channel, first linked model, than door and finally the room.
I also have an python migration error notification telling me that certain nodes use Python2 engine instead using the newer Python3. That’s why I asked about the versions
are you in 2023 i havent tried on that version ?? but if that the case you will need to download python 2.7 separately
