There already exists a great tutorial series about the complete architectural working process
from the first step until visualization as last step made by Yorik.
Look for “BIM with FreeCAD - Barcelona pavillion”
https://www.youtube.com/user/yorikvanhavre
It consists of 17 Videos, a complete tutorial from a professional!
Here is the link to the Barcelona pavillion render video, which describes everything better, then I ever could do:

Here is the link to the “pabellon de barcellona freecad model, where you also find the ifc-file

So someone can compare, what Yorik does, and what is on his/her screen
From my point of view, I would add a few points:
1. Export the FC model via ifc and install in Blender the BlenderBIM Addon.
Click “Force export as Bref” in the FC IFC preference panel
The import works fine. For any FC Windows or CW Object, 2 materials are generated in the material slot, one for the frame and one for the glass panel.
So you can change both with a few clicks. No need, to go into the edit mode or clicking faces.
2.) For the facade glass panel, I would not recommend the internal glass shader.
There are better ready to use Blender facade glass material in the Inet, which produces a more realistic relation between transparency and reflection.
You can import external material by using the “append” function.
3) Recommend to install the “Sun position” Addon in Blender
It gives you the opportunity, to set the exact location of your building.
With date and time input, you can see the effect of light and shadows, depending on your setting.
You can place several cameras in the building and can look through these cameras in the room, helpful if you have rooms with very small windows.
4.) EVEE is a fantastic realtime render, but it is not physical correct.
It has also Problems, if you have a glass behind glass situation, shadows not correct.
I use it during the design process, but make the final render with cycles
BTW: Of course, no problem with uploading my FC-File, but in this case, I would not force it. As I mention, it was an early stage of learning, I didn`t use most of the great tools, FC has.
Think about of someone, who has the first contact to FC and would download this as an example. It would lead him/her in a complete wrong direction with a complete wrong impression, what can be done with FC, at the end frustration.
Think, the great FC project deserves better than this...(bad examples, which do not show the powerfull tools, FC has) ...
it would be cool to share the FC file.
