A CAD model can quickly display an engineer’s ideas in a realistic way. And those models can be used to generate technical drawings that can communicate the information necessary to make the idea a reality. In order to generate a 3D model, designs must start with sketches that are generated within the CAD program. These computer generated sketches will appear resemble hand drawn sketches in geometry (the combination of points, lines, and shapes), but have big advantages over hand drawn sketches. One important difference between a freehand sketch and a CAD sketch is accuracy. The lines of a CAD sketch can be drawn perfectly straight, with start and end points that occur in exact locations in space. By using numeric (dimensional) constraints a line may also be given precise length, placed a specific distance from another sketch feature, or constrained to be oriented at a specific angle from another straight line. By applying geometric constraints a line can be made perfectly horizontal or vertical. If more than one line is being sketched, they can be made perfectly parallel or perpendicular, collinear, or equal in length. Lines can be constrained to be tangent to circles or arcs, and two circles can be constrained to be concentric. In order to precisely model a part, the designer must be able to use dimensional and geometric constraints within the CAD program.…

On January 18, 1978, just four years after completion, the space frame roof of the Hartford Civic Center came crashing down 83 feet to the floor after a snowstorm. The majority of the blame for this disaster was placed squarely on the shoulders of the design engineers and architects who overlooked vital miscalculations and failed to fix design flaws when they started to appear.

The first step to development is to survey the property in order to document and draw the bounds and land surface shapes. The property will be represented by various geometry elements such as points, lines, arcs, circles, and other defined geometry shapes. Surveyors use scope on tripods witch use projection of line Referenced point on a stick in order to measure the variations of the heights on the ground. This tool uses various angel theorems and postulates to find location of property boundaries, property corners, utilities and building layouts on the property. The surveyor uses the data collected to draw the property layout on a 36"x 24"sheet of paper.…

Traditionally Building Projects were illustrated with manually created drawings, information was added to these illustrations by using motes and specifications. As CAD technology progressed this system became automated, though the output remained the same. The development of the Building Information Modelling methodology has created a new way of thinking and working. It gives us ability to model with objects and minimizes tedious drafting by allowing one 3D object handle multiple 2D representations when placed in an object. The coordinated data represented in the model allows us to visualize and analyse designs and make better informed decisions.…
The aim of this project is to identify which frame is the best suited for a three storey building. The two most popular construction frames, timber and steel will be compared and the focus will be on the types of frames and construction time for both frames.…
This software can help an engineer create the invention and run it under tests on the computer. To first process the data, an engineer would use analytical software in order find trends in the results. Computer Aided Design software, or CAD software, are programs used universally by engineers to implement specific materials and aesthetics into a creation. Finally, simulation software will allow the engineer to observe how the product will behave in different environments. This is the last step of the scientific method, determining whether or not an engineer must revise the product or continue in development.…

Throughout the last few years, technology has been improving the lives of people from all walks of life and all fields of study. One of the big pieces of technology in the civil engineering field today is computer aided drafting. AutoCAD is a computer aided design software for the 2D and 3D design of certain objects or places. Computer aided drafting is widely used in the civil engineering field because of its ability to plan sites a lot easier then hand drawings, it can help design a lot of engineering supplies, and is constantly upgrading. Up until a few years ago, civil engineers would hand draw their design plans which could take a while. Computer aided drafting makes this process faster and easier. It can also lay out sites, roads, sidewalks, bridges and other engineering items. There are constant upgrades to computer aided drafting being made every year to improve the system and help civil engineers.…
AutoCAD, developed by Autodesk Inc., is the most popular PC – CAD system available in the market. This design package is a general purpose computer aided design and drafting application for your computer. The speed and ease with which a drawing can be prepared and modified using a computer offer a phenomenal advantage over hand preparation.…
