[Brief explanation of drawings]

Figure 1 is a diagram showing an example of this invention, Figure 2 is a diagram showing an interpolation curve before editing, Figure 3 is a diagram similar to Figure 1, and Figures 4 to 9 are the same as Figure 1. , a diagram similar to FIG. 2, FIGS. 10 and 11 are flowcharts showing an embodiment of this invention, FIGS. 12 to 14 are diagrams showing a conventional example, and FIG. 15 is a flowchart showing a conventional example. It's a chat. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.

Claims (1)

[Scope of utility model registration request] From a given passing point and a passing point with a discontinuous attribute (constraint point marker) added, interpolate between two passing points with two circular arcs to generate a continuous tangent curve as a whole, especially for passing points with constraint point markers. The ability to generate curves that are tangentially discontinuous at points, move, add, and delete passing points that make up the curve, and add arbitrary points other than passing points to the generated curve.
CAD/CAM with a function that allows editing such as moving and adding constraint point markers at the same time as editing curves.
