The apparatus has an evaluated value calculating meansfor calculating the complexity of the object shape and the complexity of the modeling structure of the object CAD data input by the CAD data inputting means; a searching meansfor searching the reference CAD data in the reference CAD data basein accordance with the condition of said complexity; an evaluated value calculating meansfor calculating the complexity of the object shape and the complexity of the modeling structure based on the searched reference CAD data; and a displaying meansfor evaluated values obtained by the meansand the meanson the graphic representation defining its horizontal axis for the complexity of the object shape and its vertical axis for the complexity of the modeling structure. It will be appreciated that the man-hour for evaluating large amount of various models can be reduced by means of not using a CAD system.

CAD data evaluation method and evaluation apparatus

A BOM is merged to a BOM stored in a BOM data base by means of the component identification judgment means that compares the product record in the BOM file with the product listed in the BOM stored in the BOM data base and makes judgment conformity between these two product records and a BOM rearrangement means that has a BOM rearrangement means a coding rule estimating means determining the coding compliance. A component assembly flag and a component assembly status flag are appended to the BOM stored in the BOM data base so that the expansion to the lower hierarchal layers of the component is presented.

When creating other tool path from two tool paths for cutting a work accurately and efficiently, the data on the first tool path is composed of a position vector and a direction vector of a tool for use when the work is cut while moving the tool. The data on the second tool path is composed of a position vector and a direction vector of the tool for use when the work, which has been cut according to the first tool path, is further cut. A computer uses the first tool path data and second tool path data to calculate a position vector and a direction vector of a medium tool path that is between the first tool path and second tool path.

Apparatus and method for creating tool path

A method for detecting shapes that are undesirable for efficient processing and which occur from tolerance conversion by comparing a geometric relationship of shape elements obtained from shape data before tolerance conversion with a geometric relationship of the shape elements obtained from shape data after tolerance conversion. An inappropriate shape is identified when the compared geometric relationships are not the same.
