# Hi Rafael, Commenting post [17](/?blog/2015-017): Hi Rafael, Actually the feedback was very good... Lots of questions, Lots of people from different areas were interested, specially from the electronics and CNC fields. But there were a couple of architects at the talk too, some annoyed that I didn't talk more about IFC and BIM ( we'll need another talk I guess :) ). But I think the talk managed to throw some light on how easy and cool it is to begin to write code for FreeCAD... The blender community also tweeted a lot about the talk... I'm curious to see the evolution of this!
