Creating new layers and DXF export

Question

I have a small .OSM map which has some rules set up based of whether it's deemed a primary road, secondary road, path etc. What I would like to do is branch each one of these out to its own layer for exporting to a DXF. I've tried to duplicate the layer and removed the conditional formatting but when I export the DXF it still contains all of the data.

Is there any way to do this?

Ive done it now. Using the select features by value you can narrow the selection down with the different options.
