  In metropolitan cities such as Tokyo, the increase in air pollution caused by gasoline cars, strengthens the need for electric cars. Although vehicle companies make a lot of electric cars, the number is still dwarfed by that of gasoline cars. A convenient way to increase the number of electric cars is to convert existing gasoline cars.
 The authors have studied a convenient way to create a 3D model for an engine room using a 3D-SCAN system. The open issues were (1) to obtain highly accurate three-dimensional measurement data of an engine room, (2) to keep a highly accurate conversion ratio from three-dimensional measurement data to three-dimensional design data, and (3) to reduce working hours and make it less of an expert dominated field.
 This paper shows a convenient way to convert 3D point data to 3D CAD data for an EV conversion with a 3D digitizer and the ICP method to solve these issues.
