3D registration between IFC model and 2D drawing PDF

In ClosedBIM we see some solutions here, from Skanska to other solutions, mainly in FM area

But it would be good if implement it in IFC, so there would be two options:

  1. Improve IFC to be able to join/integrate PDF and IFC
  2. Build a middleware which integrates PDF and IFC (Which almost many have done this, but the first option is better)

However, personally think out of the box and I think even instead of PDF, it’s better develop preferred IFC based on “Page Layout

Hope this suggestion helps you too: This
