In the export setup box colour ID for both beams (structural framing) and floors, in cut profile, are set to 3 however they dont appear the same thickness on screen, they dont export the same thickness and they dont plot the same. Once exported to CAD beams have a line weight of 0.25 and floors 0.50 I am trying to get them both to have line weight of 0.35

Any ideas where I am going wrong??
