Abstract
Disclosed is a method for designing a development drawing of a developable surface, the method including the steps of: setting a control contour from a circumference surface of a 3-dimensional model; performing an algorithm LIDM-GC-Dvlp to search a control point set; outputting a control point of a profile curve; visualizing a developable surface typed general circumference surface; modifying a design by a user depending on the visualized result; selecting a developable surface segment intended to generate the development drawing; and performing an algorithm LIDM-GC-Plane-Dvlp for the control point to generate the development drawing.
Claims6
A computer method for designing a development drawing of a developable surface, the computer method being executable within a computer and comprising:
- setting a control contour from a circumference surface of a 3-dimensional model;
- executing a first algorithm LIDM-GC-Dvlp within the computer to search out a control point set;
- outputting a control point of a profile curve;
- imaging, within the computer, a developable surface type general circumference surface;
- modifying a design of the user viewable development drawing of a developable surface by using user input depending on the imaging result;
- selecting a developable surface segment intended to generate the development drawing;
- executing a second algorithm LIDM-GC-Plane-Dvlp within the computer for the control point to generate the development drawing;
- and
- drawing the development drawing on an essentially planar object such that the entire surface of a cubic figure can be effectively generated using sequential factoring curves without generating a finite number of middle contours.
