COMPUTING DEVICE AND METHOD FOR EXTRACTING FEATURE ELEMENTS OF PRODUCT FROM DESIGN DRAWING
First Claim
1. A method of a computing device for extracting a feature element of a product from a design drawing of the product, the method comprising steps of:
- receiving a selection of a point and a curved surface related to the feature element in the design drawing;
calculating a minimum distance between the selected point and an outline of the selected curved surface;
identifying whether the selected curved surface or the outline of the selected curved surface is the feature element in the design drawing by comparing the minimum distance with a first preset value;
determining a measuring type of the feature element according to a point cloud of the feature element;
extracting sample points composed of the feature element according to the measuring type and attribute data of the feature element; and
displaying the sample points on a display screen of the computing device.

Abstract
In a method for extracting a feature element of a product from a design drawing of the product, a point and a curved surface related to the feature element are selected from the design drawing. The method calculates a minimum distance between the selected point and an outline of the selected curved surface, and identifies whether the selected curved surface or the outline is the feature element by comparing the minimum distance with a first preset value. The method further determines a measuring type of the feature element according to a point cloud of the feature element, and extracts sample points composed of the feature element according to the measuring type and attribute data of the feature element. The sample points are output on a display screen of the computing device.
