摘要： PURPOSE:To offer the processor which can select some of many complicate figures efficiently. CONSTITUTION:When an area crossing a figure 2 is specified with a cursor 23, only the figure crossing the area is put in a selected state. At the same time, the number of the figures put in the selected state is confirmed and when the number is plural, the area is displayed by enlargement/rotation processing. Then similar processing is repeated until only the desired figure is put in the selected state. Consequently, when one part is selected among many complicate figures, the repetition of figure specifying operation is eliminated. Further, only the figure which is specified first is enlarged and rotated, so the calculation time is shortened to speed up the processing. Further, the operability is improved.

摘要： PURPOSE:To facilitate the partial correction of a generated curved surface by designating the rotational frequency and the magnification of a feature curve at an optional point on a control curve in addition to the designation of the control curve. CONSTITUTION:An input command processing part 3 is provided together with a coordinate conversion matrix component extracting part 9, a calculation part 13 for geometric value data on a curved surface, and a patch curved sur face data generating part 17. When a feature curve is swept along a control curve for generation of a curved surface, the rotational frequency and the magni fication of the sweeping feature curve are obtained as the data independent of the control curve. Thus the rotational frequency and the magnification of the feature curve can be designated independently of the control curve even in correction mode. Then the partial correction is attained for the curved sur face.

摘要： PURPOSE:To reduce the input operation of a designer by inputting a rounding radius in a ridge direction to link a three-dimensional form consisting of the ridges and endpoints structured in a computer to the endpoints, and generating the ridges to link the corresponding two endpoints. CONSTITUTION:The designer inputs three ridges L1-L3 and rounding radiuses R1-R3 on the common endpoint side (a V side) of the ridges, and generates a corner rounding ridges E1-E3 (figure a). A computer 3 deletes the unnecessary ridges inputted by the designer (figure b). The computer 3 requires the input of ridges L4...L13 to be inserted between the endpoints of the ridges (for example, E1-E3) of the respective corner rounding parts to the designer, and obtains the final form (figure c). The computer 3 inputs the combination of the ridges constituting surfaces from the designer, and defines the surface fixed by the combination of the ridges. For example, by designating the combination of E1, E2 and E3, a surface S1 is generated, and by designating the combination of E1, L6, E4 and L7, a surface S2 is generated.

摘要： PROBLEM TO BE SOLVED: To enable a developing test of an on-vehicle information terminal device and an on-vehicle navigation device without replacing data in a beacon checker device by inputting the light or radio wave data from an external terminal device connected to the beacon checker device. SOLUTION: A beacon checker terminal device is controlled by a control part 102, and starts an interactive part 103, and designates a data type (the light or a radio wave) and a file name of data to be inputted, and inputs them from an input part 101, and preserves them in a data storage memory 104. Next, data preserved in the memory 104 is transmitted by a data transmitting part 110, and is sent to a beacon checker device 109 through an RS-232 C drive 107 and an RS-232 C cable 108. Next, when light data is transmitted, answering light data is received from the beacon checker device 109 by a light receiving part 105, and is analyzed by the control part 102. When received data is preserved, a preserving file name is designated by the interactive part 103, and is transferred to the memory 104 from the control part 102, and is preserved.

摘要： PURPOSE:To facilitate the control of the design information and to automate the designing with the reduction of labor by repeating the change of the shape data or the attribute data in order to satisfy the restriction data and detecting the conflict of restriction expressed in the restriction data. CONSTITUTION:A restriction conflict detector 2j detects whether the data changed by the 1st, 2nd and 3rd changing means conflicts with other shape data, attribute data or restriction data or not. At the same time, the processing states are monitored for an inter-attribute restriction processor 2f, an inter- attribute shape restriction processor 2g, and an inter-shape restriction processor 2h respectively. If the processing of each processor is not stopped at the prescribed time or in the prescribed frequency, the processing is forcibly ended. Then, this fact is outputted to an output device 4 in a message. Furthermore, five processors 2k-2o take the data out of a storage 3 and transfer them to the device 4. Meanwhile, a processor controller 2p controls the processing of each processor.
