working with a 3d model from another program from a online source

[Anonymous]

I purchased a 3d model of a Porsche 550 spyder. I don't know what type of file it is. 

and would like to divide it up into sections after scaling it to size so I can print 1:1 scale profiles of the model 

modify scale is the only thing so far I can get to work with the drawing.

I've scaled it to size by measuring the wheelbase  knowing the Porsche wheelbase 

id like to use the prints as templates to build a wood station buck to build the body with aluminum 

so far I haven't invested in fusion 360 Id like to know if what I'm wanting to do will work 

I own a hp 36 inch t520 Designjet 

so breaking or splitting the drawing up would help to just print what I want 

I've already tried to just trace around the section I want to print using section analysis but this isn't permanent 

I've drawn one profile of the body so far I haven't been able to get it to print 

yes I'm not very good with cad kind of a newbie 

any ideas would be appreciated .....id like to be able to do this quickly 

the methods I've tried so far are very time consuming
