It is necessary to set various entry conditions such as radius, character size, and pitch. Conventionally, when setting this kind of entry condition, a plurality of setting items required for each command are selected while opening a condition setting window or the like for reference. In this case, the previously selected entry condition may be displayed, but if an entry condition different from the previously set value is set, it is necessary to set a new condition again. In particular, when modifying drawings, new drawing elements may be added with the same entry conditions as specific drawing elements, but even in such a case, the entry conditions after system startup will be set to the previously set values or default values. Therefore, the same entry conditions as the specific drawing element must be set again.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a functional block diagram showing the configuration of a CAD system that realizes a drawing element entry condition method according to an embodiment of the present invention. This system is a mouse,
An input unit 1 including a coordinate input device such as a joystick and a tablet device and a keyboard, a CAD processing unit 2 including a CPU and predetermined software, and an external disk device, a drawing element storage unit 3 such as a working memory.
And a display unit 4 such as a color CRT display device or a color liquid crystal display device.

The CAD processing section 2 has an entry condition setting section 11 for setting entry conditions for creating drawing elements based on input information from the input section 1, and entry conditions set by the entry condition setting section 11. An edit processing unit 12 for appropriately editing a drawing element according to the drawing, and a drawing displayed at a position on the display screen designated by the input unit 1 when "element reference" is selected by the operation of the input unit 1. A reference element selection unit 13 for selecting an element as a reference element, and a display control unit 14 for displaying necessary information on the display unit 4 at the time of processing in each of these units are provided.

The entry condition setting unit 11 includes a reference element selection unit 1
Controlling the display control unit 14 to display the attribute information of the reference element selected in 3, on the display unit 4 in the form of a command panel,
Based on the operator's selection operation on this command panel, the attribute information is appropriately corrected or confirmed, and this is set as the entry condition.

Next, the operation of the present system thus constructed will be described. FIG. 2 is a flowchart showing a process of setting the drawing condition of the drawing element in the writing condition setting unit 11 and the reference element selecting unit 13. This process is started when the entry condition setting mode is selected from the main menu (not shown). When this process is activated, first, the entry condition setting unit 11 sets the previous entry conditions or default values in a working area of a memory (not shown) (S
1), a command panel for setting entry conditions is generated, and this command panel is displayed on the display unit 4 via the display control unit 14.

FIGS. 3 and 4 show an example of the displayed command panel. FIG. 3 shows the case where the drawing element is “circle” and FIG. 4 shows the case where the drawing element is “character”. The command panel 21 includes a drawing element attribute information setting unit 22 and a drawing element shape information setting unit 23, and an arbitrary item can be selected by a cursor 24 that moves according to an operation of the input unit 1. As the attribute information, the pen number,
Line types, colors, virtual elements, angle conditions, etc. are displayed as setting items. As the shape information, the radius of the circle, the size of the character, the inclination, the pitch, the line feed width, etc. are displayed as setting items. When a pen number is set as the attribute information, for example, a pen selection panel 25 showing the relationship between the pen number and its color is displayed at the cursor position so that a pen of a desired color can be easily selected. Has become.

The entry condition setting unit 11 executes a necessary item correction process for the command panel 21 based on the input information from the input unit 1 (S3). When the return key or the like of the input unit 1 is input, the entry conditions are confirmed and the process ends. On the other hand, when the “element reference” displayed on the command panel 25 is selected by the cursor 24, the entry condition setting unit 11 causes the display control unit 14 to display the lower side of the display screen 31 as shown in FIG. Message 32 "Please specify the element to refer to" is displayed (S
4). When the cursor 24 operated by the input unit 1 such as a mouse is hit in the vicinity of a specific drawing element 34 while the drawing element information 33 is displayed on the display screen 31, the reference element selecting unit 13 is activated, The coordinates of the hit point are imported from the mouse coordinate storage unit (not shown) (S
5) Then, a drawing element passing through (in the vicinity of) the fetched point is selected from the drawing element storage unit 3 (S6). The attribute information of the selected drawing element is set as a writing condition in a working area (not shown) (S7), and a command panel is generated and displayed again (S2).

That is, as shown in FIG. 6, the drawing element data 51 in the drawing element storage unit 3 is classified and stored for each element type such as a straight line, a circle, an ellipse, and a free curve, and each drawing element is stored. Is a pointer 5 that points to a storage area in which actual values such as start point coordinates, end point coordinates, center coordinates, and radius are stored.
2 and attribute information 53 included in the drawing element. In the storage area designated by the pointer 52, actual coordinate data 55, radius data 56, etc. are stored.

Therefore, the entry condition setting unit 12 may take in the attribute information 53 of the reference element and generate the command panel 21.

By reflecting the entry conditions set by the above process in the process in the edit processing section 12, it becomes possible to enter a new drawing element under the same entry condition as a specific drawing element.

[0017]

As described above, according to the present invention, when a drawing element that has already been created is selected as a reference element, the attribute information of that reference element is displayed on the display screen, and this attribute information is modified appropriately. Alternatively, since the entry condition can be set by confirming, the setting operation of the entry condition of the drawing element becomes extremely simple.
