A brief report of the design work on buildings of the Japanese Hadron Project has been published as a JHP-report (JHP-15). The design of the buildings has to be modified to fulfill the detailed design works on accelerators and experimental facilities which are in still progress. Modification of drawings ie easy if they are prepared as data in a CAD system. Most of the drawings have therefore been newly prepared as data in the CAD system. Some of the drawings in JHP-15 have been modified to meet the recent study of the beam line optics requirements for the JHP beam line. The CAD system used is MiniCad+ by GRAPHSOFT INC. Data of drawings in 3.5 inch floppy disks can be distributed. (author).
