Autodesk Revit Architecture

[#1]

Currently I have created Rooms and a Legend such that I have a coloured Plan View by Room department.

The colour boundaries extend to the centre line of the defining Walls. Is there a way to get the coloured zones to follow the Room boundaries?

I realise I can overwrite the Wall pattern and use a Solid pattern to hide the colour - but this is not what I want ...

Maybe the view is not set to Hidden but Wireframe?

Thank you so much for answering ...

Something so simple - I must take more coffee breaks ..
