Hi, any idea about 'World Coordinate' issue?
I don't think I'm the right one to decide how this could be solved. I don't work in the architectural field and have no experience with other Architectural CAD applications. So hard for me to suggest something
I modified the Arch Site a bit because:
- Modelling a house is way easier when one can use the global axis as reference Points
- But when Looking on the finished model, it is Pretty hard to see where North (or more important for me South) would be in the real world.
When Looking on the model Positive Y Always feels like North for me. So I decided to give the Arch Site a Compass so that one can see where True North is located. After some discussion in this thread I extended the Site so that it could calculate the "Declination" property on the fly and it can rotate the whole model so that the True North aligns to the Positive Y axis.
This makes it easier for me to see how the Building will look in real life
If this does not make a lot of sense for a professional Architect it is totally fine for me

So we type the terrain points manually in excel and transform the origin after choosing a
reference point in the cad model. This only works because we have less then 100 points.
I think your use case could be implemented either as a standalone macro or in the Arch Site directly. I think of importing the geometry as it is (a few hundred Kilometers away from the origin in FreeCAD) and give the Arch Site a "Reference Point" Vector, when set it will transform the shape so that the "Reference Point" Matches the Origin.
I pretty much like @yorik's idea. Simply model the whole Thing like it is best for you. Use the origin and the global axis or not. And afterwards set the offset Transformation somewhere and use this information where the world coordinates have to be used (Exports, Techdraw Pages,...).
The offset angle is already in the Arch Site. Adding a Reference Point would give us all the Information required to calculate the real coordinates on the fly.
