I want to convert IFC to Cityjson.

At this moment in time this extraction method is slow and does not return solids.

-> Looking at the above phrase in wip, does it mean that the shape is not extracted for Lod3.0 or higher?

It's currently progressing like this picture, but it's too slow.
Will the results be extracted even if it is slow?

For most input there will still be output for LoD3.2. However, it will be a collection of untrimmed surfaces that are (partially) representing exterior of a building. The process is currently slow because it is still experimental code... so its a single threaded process and very badly optimized.
