Concerning systematization of an interlocking table making we developed for a drawing for ledgers until now. However, an interlocking table made in the design spot of JR tends to be drawing the construction before and after with yard improvement coexisted. On this account we developed that the system can support making by a drawing for construction. In development, we simplified a data structure so that a drawing for construction had a complicated form, and we realized the user interface that did not have a sense of incongruity with making a drawing for ledgers. Regarding the interlocking movement list for construction, we received correspondence automatically in construction before and after of an interlocking movement list for ledgers.
