Importing AutoCAD plotstyle to Vectorworks

[S_N_ARCH 0]

we have a project outside of the UK and working with the local architectural office there.

We use Vectorworks and they use AutoCAD. For the better workflow, we said we can use their layer system.

I managed to import their dwg files but how do i import their plotstyle? What is the best way to do it?

I have their CTB file but can't work out how to import the plot style to vectorworks.

Thanks for the help.
