what is conic section in engineering drawing?
233349
Conic sections are the intersections of a right regular cone, by a cutting plane in different positions, relative to the axis of the cone. PARABOLA. The parabola is a conic section, the intersection of a right circular conical surface and a plane to a generating straight line of that surface.

Basic tips for civil engineering drawing Types of lines include the following: visible – are continuous lines used to depict edges directly visible from a particular angle. hidden – are short-dashed lines that may be used to represent edges that are not directly visible.

A two-dimensional figure, also called a plane or planar figure, is a set of line segments or sides and curve segments or arcs, all lying in a single plane. The sides and arcs are called the edges of the figure. ... The inside part is called the region enclosed by the figure.

An isometric drawing is made up of lines on a flat plane, and each line can be described in terms of x-y coordinates. There is no depth or z-axis information. Although it depicts a 3D object, the drawing itself is 2D in the same sense that a landscape painting is 2D.

Centre lines are drawn to indicate the exact centre of a component being drawn. They are made from a series of lighter long and short dashes. Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details.

2D drafting and drawing is the process of creating and editing technical drawings (US site), as well as annotating designs. Drafters use computer-aided design (CAD) software to develop floor plans, building permit drawings, building inspection plans and landscaping layouts (US site).

Euclid's Postulates. 1. A straight line segment can be drawn joining any two points. ... If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two Right Angles, then the two lines inevitably must intersect each other on that side if extended far enough.

Civil drawings are associated with detailed earthworks, falls, drainage, etc. As structural engineers, we design any structure in any material (but mostly steel and concrete) to resist any possible combinations of gravity, mechanical and environmental loads to prevent collapse or excessive deflection or vibration.

In geometry, a diagonal is a line segment joining two vertices of a polygon or polyhedron, when those vertices are not on the same edge. Informally, any sloping line is called diagonal.
