Controlling the wireframe

[Hameed]

Hi,

In this model I need the to have some parts of the wireframe bigger than the others (the vertical ones seen in the elevation). I thought about making two renderings for teh two sizes then editing them in photshop but that will take lots of time for the 2dviews and a life time for 3d one.

 

Later on I will have to build a model for this structure so am wondering if there is anyway I can "extract" the sections (the ones that I need to enlarge in the first question) so I can print each section seperately?

 

Another thing, how can I render a wireframe using Brazil?

 

Thanks
