I have a problem where steel beams are displaying as hidden detail in a plan view where there is nothing hiding them! The floor which sits on top of the beams is hidden in the plan view yet the beams still display hidden.
I have tried to use the lineweights tool to make them solid but this selects the entire beam and not individual lines - in some areas I need some of the beam to display dotted where it extends under a precast hollowcore slab, so i need the line to transition form solid to hidden where it goes under a hollowcore unit.
I have attached an image which explains this more clearly than I can describe.
What is even more confusing is that the trusses are displaying correctly and they are normally the bane of my life!
