Electric design device
First Claim
1. An electronic design device comprising:
- a first input device;
a second input device;
an output device for displaying a graphic representation including a position marker, wherein information entered using the first input device moves the position marker on the output device; and
a data processing device generating a curve as a function of information entered using the first and second input devices for display on the output device, the curve being generated so as to have a fixed section having a fixed path and a freely movable section connecting an endpoint of the fixed section to the position marker so as to form a smooth transition between the fixed section and the freely moveable section, wherein a position of a curve marker is shiftable along the curve based on information entered using the second input device, and wherein, in response to receiving a fix command at a time when the curve marker is disposed along the freely movable section, the data processing device fixes a partial section of the freely movable section between the curve marker and the fixed section and joins the partial section together with the fixed section so as to form an extended fixed section.

Abstract
The present invention relates to an electronic design device having an output device for displaying a graphic representation, a first and a second input device, and a data processing device. When information is entered via the first input device, a position marker moves on the output device. The device generates and displays on the output device a curve having a fixed section having a fixed path and a freely movable section between the fixed section and the position marker. The device generates the freely movable section so that the freely movable section and the fixed section together form a smooth curve. When information is entered via the second input device, the position of a curve marker located on the curve is shifted along the curve. If, when a fix command is received, the curve marker is located in the freely movable section, the device converts the partial section of the freely movable section between the curve marker and the existing fixed section into a further fixed section.

12. A method for generating and displaying a curve that is processable by a computer, the method comprising:
-
moving a position marker on an output device as a function of information entered via a first input device;
generating and displaying the curve having a fixed section including a fixed path and a freely movable section on the output device as a function of information entered via the first input device and a second input device, wherein the freely movable section is generated so as to connect an endpoint of the fixed section to the position marker and so as to form a smooth transition between the fixed section and the freely moveable section;
shifting a position of a curve marker along the curve as a function of information entered via the second input device;
in response to receiving a fix command at a time when the curve marker it disposed along the freely moveable section, fixing a partial section of the freely moveable section between the curve marker and the fixed section and joining the partial section together with the fixed section so as to form an extended fixed section. - View Dependent Claims (13, 14, 15, 16, 17, 18)
