Hi guys, I am recently starting a project for my thesis, can anybody give me some samples of details such as elevator shaft details?

Have you tried looking in the CAD Blocks area here or over at the CAD Block Exchange?

A simple search of the Internet would have turned up something like this.http://1012.aipdesign.com/CONSTRUCTION%20SET/1012-CPM%20MULTIPURPOSE/A5.5.1-%20Elevator%20Shaft%20Section.dwg%20Layout1%20%281.pdf
