i have just post two little tutorials of a small architectural project on you tube, this is the link:
The objective is to show how FreeCad can be already part of a professional workflow.
I've tried to do my best to show the overall steps in the workflow, paying attention at some phases of the modeling like placing windows, make the array and others. So it's not to be intendend like a technical tutorials, like the ones published by Regis, (i suggest everyone that want to learn arch/bim workbench to see his videos) but just to show the potential that the Bim workbench has.
This is the first two parts of the tutorial, it's already little outdated compare to the V.0.18 daily build, anyway i hope this could be useful.
I hope to show the energy simulation soon.
