Multi LoD file adds empty attributes to all layers

[balazsdukai]

I'm loading a multi-lod file with BuildingBarts which has attributes only on the Building.
I load the file by splitting the lod-s to layers.
Then each lod-layer obtains the attributes from the Building, all with NULL, although they don't have attributes on their own.

This is true. It's expected that all layers have all attributes that are identified in the whole dataset. The same applies to per object type layers.

I assume that it's not that problematic, but I can imagine that it can be annoying. I'll, therefore, flag it as an enhancement.

I guess there could be an option to remove unused fields in layers.

Any thoughts on that?

Perhaps it would be useful to have an option to inherit attributes from the parent? Specifically in cases where you only want to work with one LoD.

That's a great point! I think it would be really useful for 3D BAG specifically.
