In this paper, we discussed about As build data measured with 3D laser scanner, and the application of it. We measured one of the industrial heritages "Gunkan-Island" which the collapse is advanced. We carried out a rendering of point clouds as a sphere. That picture has the texture information such as pictures to add the shading in the pillars, beams and damaged part. So we can support to make damaged plans by using the rendered pictures. We solved that the width of cracks below resolving power of the photograph taken with the digital camera, has a correlation between the numerical data of features and the distribution width of colors. We created the index which Crack Index is "the numerical data of features and the distribution width of colors" and made a system for assisting in drawing the cracks. We could reduce the cost and term for tracing cracks.
