The relative priority of the layer, expressed as normalised integer range [0..100]. Controls how layers intersect in connections and corners of building elements: a layer from one element protrudes into (i.e. displaces) a layer from another element in a joint of these elements if the former element's layer has higher priority than the latter. The priority value for a material layer in an element has to be set and maintained by software applications in relation to the material layers in connected elements.
@sahrul are you receiving any error message? If so, can you please file a bug? Are you sure you have upgraded to the latest versions of both Blender and Bonsai? A video recording of what you're doing will also really help.

not working for me
@sahrul Try and download these files and try to reverse engineer what's going on...

thanks @c4rlosdias @theoryshaw
A beautiful wall layer junction — how can it be achieved?

Play around with that value...

Wow..like Archicad
I've tried the ZIP file, but it doesn't work.

I can't download that file
Yeah, just realized that it doesn't work either.
You can sync the repo, but it takes a little bit of know how..
If you're interested in knowing how, this tutorial could help:https://hub.openingdesign.com/OpeningDesign/OD_Library/src/branch/master/BIM/Workflow/OD Workflows.md#file-management-on-windows
Have been meaning to clean this tutorial up one of these days. :)
There's countless other resources on the web that explain how to sync a repo too.
