Using this analytical model information delivery device, it is possible to quickly create analytical models even when the designer and the analyst are different people. This analytical model information delivery device is provided in a device for creating numerical models from CAD data. A shape search unit searches the components making up the CAD data and extracts features, and matches the extracted features with shape creation rules pre-registered in an analytical modeling means database. Further, when modifying a three-dimensional CAD model using the shape creation rules, an input result display unit highlights the modification area of the three-dimensional CAD model modified in accordance with the shape creation rules. A model conversion unit creates a numerical model from the modified three-dimensional CAD model. A shape processing unit further interactively modifies the modified area of the numerical model displayed by a modeling area display unit.
