Hi Brian,

 It looks like an awful lot of work you've done there.  Has any of it made its way back into the main tree?

 I'm also interested in knowing the extent of the work you did with IDF. A number of people on the users' list have said that they need IDFv3 import since their clients send them IDF files. I'm convinced now that IDF export is also essential; some of my clients have sent me PCB mechanical data as IDFv3 which I then import into SolidWorks and tweak.  Although I still plan to use FreeCAD to create actual mechanical assemblies which can be sent to mechanical people in STEP format, IDF is far more compact even though no fine details are possible and a number of people have told me they only want IDF and nothing more.
