1 The theory foundation of engineering drawing is descriptive geometry.

2 Solutions to problems in descriptive geometry such as finding the relative positions between straight lines between a straight line and a plane, and between planes are found by computerized graphics.

3 One of difficulties in descriptive geometry theories is to draw the intersection created by two general position intersecting quadric surfaces.

4 Descriptive geometry of the problem is to study geometry of space and graphic icon of the law school he was an engineering drawing of the theoretical basis.

5 Aim The coming of western descriptive geometry into China in the late Ming Dynasty is explored and analyzed systematically.

6 Studying the descriptive geometry course was the process of knowledge construction, which mainly included organizing knowledge unit and knowledge structure chain step by step.

7 In this paper(sentencedict.com), the method of analytic descriptive geometry is applied to set up the parameter function of the intersection line ofparaboloid and cylinder whose axes are inclined to intersect.

8 According to principle of descriptive geometry, the area of plane equals projection of the plane divided by cosine between plane and projection of plane.

9 The method in line with descriptive geometry, which is very simple and intuitional, is presented as a way of solving the problem of indirect position of robot arm.

10 This paper introduces the development, the function and feature of the CAI software for Descriptive Geometry.

11 As to the method of calculating the relative movement force and total fault displacement of two walls of a fault, there are the method of descriptive geometry and the method of diagram analysis.

12 Determination of the angles between two planes is an important yet unsolved problem in descriptive geometry of N-dimensions.
