I am an engineering student at the Tulsa Community College. I have a term paper due and I am going to create the report cover graphic using Solidworks. I am looking for dimensioned drawings for the construction of a land based oil rig. They need to be in a digital format: either PDF or JPEG. They don’t have to be current and older drawings (50+ years) are actually preferable. If you can help me out, please respond to this posting.
