I'm looking for a freelancer with excellent CAD skills to put together shop drawings for us. See the attached original mechanical air conditioning DWG drawing, and also see the attached as-built drawing of how the duct work was actually installed at the job site. We need for the existing/new duct work to be drawn onto the DWG file. There will be additional changes which we'll provide at a later date. It shall have new duct work dimensions, duct work heights (bottom of duct, and top of duct), etc.
