Converting ifc file into idf format for TRNSYS

how to convert BIM data ifc file into idf format for using as a input file for TRNSYS?
I am able to import ifc file into SketchUp. But while saving as a idf format using TRNSYS 3D Plugin, no geometry or dynamic components is being exported.
Could someone please help me?
what is the right procedure to do it successfully?

PS: I am new to SketchUp.
