Anyone had an experience of the 3D registration between IFC model and its relevant 2D drawing PDF?
In the software implementation group in buildingSMART Japan is now trying to define the common specification of the position matching between an IFC model and its 2D drawing PDF exported from a BIM software.
The 2D drawing PDF may contain the origin point, projection direction, and paper plane, to match the IFC 3D model and 2D drawing.
For example, a BIM software could export the 2D drawing PDF with the parameters of vector and position information embedded in the particular layer with in the exported PDF. Any IFC viewer can utilize the parameters to match the position and direction between imported IFC 3D model and its relevant 2D drawing PDF.
The relationship between IFC data and 2D drawing could be realized by proving IfcProject.GUID which is added into the embedded parameter in the PDF.
As you know, BIMx has already realized the integration of 3D model and 2D drawing. We would like to realize the same function by openBIM ecosystem.
