Expand API with CRS functionality #139
Description
Description 📝
I am not sure how IFC usually displays its CRS, but in general for any BIM model, a (Coordinate Reference System) CRS id would be essensial information.
In large construction projects as models could be in one CRS in the beginning of a project and another in the end of the project (example railroad/road). Another case, would be if you are to integrate the BIM model to other GIS Systems where the CRS is in different systems and you need to do coordinate transformations. Of course you could ask the user to give the input, but it would be better if the model could be read it from the data file. A id upon the vertical CRS is also important information.
Is this something which is on the road chart? That is, to put the CRS identificator to something like a fragmentModel.GetCRS() function and abstract the data search for the correct CRS identificator from the user.
The origo (in global coordinates) are also essensial information to store as it is essiensial to connect the BIM model to the other systems.
