Cheers for this. Will leave to @martin1cerny to review formally as it's his area. Would be good to understand the approach here, and how standard an approach this is -...

How are you generating the wexbim - can you show the code? I've just tested and it renders fine: Looking at the model, the Wall is modelled as an assembly/aggregation...

Presumably you're saving the (wexbim) MemoryStream to a file at some point? Or are you streaming it somewhere? Hard to reproduce without seeing that. Can you also confirm which the...

Thanks, so I have confirmed that's an issue in the latest v5.1 code, and is reproducible in wexbim/web viewer and in Windows UI. It's been broken for a long while...

Hi do you want to email me (email on my GH profile) and I'll get you invited to the preview nuget feed?

Good suggestion - this does seem an oversight that we don't have a `removeStyle()` in the same way we have `removeState()`. Shouldn't be a big task - If anyone wants...

Can you show your code - or at least the salient zoom code? Are you using: viewer.[zoomto()](https://docs.xbim.net/XbimWebUI/classes/_viewer_.viewer.html#zoomto)

It's likely because `arg.xyz` is null so you're not entering that path. Try moving the `zoomTo` call outside of that conditional logic. xyz is the inferred click position in 3D...

OK - reproduced this. It looks like the bounding box is not being calculated correctly on elements in this model so we're zooming to the wrong spot. My guess it...

Sounds like two features in play here: 1. Generate a 2D 'drawing' / footprint file from the 3D model using levels defined in the model. This would really be a...
