Geometric Construction in Engineering Drawing: Lecture Highlights

Slide Note

Geometric construction involves creating primitive geometric forms like points, lines, and planes to define objects in space. The lecture covers the basics of 2D geometric primitives, such as points, lines, circles, and arcs. It explains the significance of points and lines in technical drawings and explores different types of angles and triangles in geometry.

Engineering Drawing Lecture 3 and 4 Geometric Construction

Geometric Construction Construction of primitive geometric forms (points, lines and planes etc.) that serve as the building blocks for more complicated geometric shapes. Defining the position of the object in space Primitive geometric forms Point Line Plane Solid etc

solids solids

The basic 2-D geometric primitives, from which other more complex geometric forms are derived. Points, Lines, Circles, and Arcs.

point A theoretical location that has neither width, height, nor depth. Describes exact location in space. A point is represented in technical drawing as a small cross made of dashes that are approximately 3 mm long

Line Line A geometric primitive that has length and direction, but no thickness. It may be straight, curved or a combination of these. Lines also have important relationship or conditions, such as parallel, intersecting, and tangent. Lines specific length and non-specific length Ray Straight line that extends to infinity from a specified point
