A method for drawing a circuit diagram within a semiconductor circuit using a computer. The drawing method uses a drawing device for drawing a circuit diagram and a memory for storing symbol data representative of symbols of fundamental elements constituting the circuit diagram and attribute data representative of the fundamental elements. The fundamental elements include a bipolar transistor, an FET, a resistor, a capacitor, a diode, wiring, and a pad. The method includes the steps of judging whether or not, among fundamental elements of the same type, the symbol represented by the symbol data corresponding to the attribute data of the fundamental element is presently displayed by the drawing device, judging whether or not, when the symbol corresponding to the attribute data is not presently displayed, the symbol data representative of the symbol corresponds to the attribute data is stored in the memory, and changing, when the symbol data representative of the symbol corresponds to the attribute data stored in the memory, the symbol represented by the symbol data into the symbol presently displayed to express the changed symbol on the drawing device.
