Why do my circular extrusions not show the sides in layouts

I am using wireframe mode to make a layout and all my tubes don’t show the sides ? So for a washer on a bolt i only see the front and back face from top view? How can I stop drawing fake lines to connect these two?> I set show isocurves but that doesn’t do it… any advice is appreciated ., thanks

increase the isocrv density on the properties tab.
