The use of Computer Aided Design (CAD) in forensic science is not new. However CAD did not become a (quality) standard for crime scene sketching. If the crime scene sketch is an effective way to present measurements, it must respond to accuracy criteria to supplement the documentary work by note taking and crime scene photography. The forensic photography unit of the Zürich Police changed already some years ago from hand drawn crime scene sketches to CAD sketches. Meanwhile the technique is used regularly for all major crime scene work. Using the Rolleimetric MR-2 single-camera measuring system combined with commercial CAD-software, crime scene sketches of a high quality standard are obtained.
