TLE-ICT-Technical Drafting Grade 10 LM. Module 1 Participate in Workplace Communication. It used to be that a drafter or engineer would create these drawings out manually, using drafting boards, protractors, and triangles, pen and paper to get the job done.
Naturally, this was a rather error-prone process that did not always convey the object effectively. Today, the whole process of creating technical drawings is much more streamlined. Using computer-aided design programs like AutoCAD, a skilled engineer can depict your invention on any or all of the technical drawings above with total precision and accuracy. In addition to AutoCAD, another program commonly used to create high-quality technical drawings is SolidWorks.
The main benefit of using a program like SolidWorks is that it lets you specify a feature or several features of your invention and hold that feature constant regardless of other changes you make to the design. Wikipedia offers a practical example:. SolidWorks allows you to specify that the hole is a feature on the top surface, and will then honor your design intent no matter what the height you later gave to the can.
The benefit to you as an inventor should be clear.
Categories you should follow
Beginning from a simple 2D sketch, an engineer can use a program like SolidWorks to draw out your invention with its features pumps, hooks, handles, or what have you as the foundation, making changes to the size, shape, or texture while ensuring that the critical features of the invention remain prominent and intact throughout. This, in turn, enables you to visualize what your invention would look like in different shapes and sizes before it physically exists.
SolidWorks also contains simulation technology that allows your engineer to see how a certain design would behave as a physical object.
For instance, whether your invention will lose durability at a given size or weight can be gauged using simulation. Designs deemed problematic or cumbersome are then abandoned on the computer screen, at relatively low cost, rather than after being physically created.
Chances are that technical drawing of these drawings contains different features, sizes, geometric dimensions and other differences from the drawings before or
technical drawing it.
However, because of the rollback feature, you or your engineer can quickly and easily modify an older drawing in any way deemed necessary without messing up the other drawings. A typical drawing created with SolidWorks — of a stapler, in this case — looks something like this:.
This becomes important when it comes time to develop a working prototype of your invention, and especially when it comes time to mass-produce it. Without detailed technical drawings that draqing manufacturer can take into his hands and understand, you most likely will experience serious delays and costly errors.
Difference Between Drawing and Painting
As noted, the main people who will be creating and using technical xrawing of your invention are engineers. The main difference between technical drawings and other drawings is the degree of standardization. Rather than simply sketching your invention, an engineer drafting a technical drawing will meticulously draw it out in accordance with industry-wide standards for everything from layout, line thickness, symbols, descriptive geometry, text size, notation, dimensioning and "kind" projections.
This means that any similarly qualified engineer can look at your technical drawing and understand exactly what it represents with minimal explanation from you.
An example of a technical drawing an engineering drawing, in this case for a machine tool is shown below:. Engineered drawings such as these unambiguously represent the proportions and dimensions of the invention.
Every angle, nook and cranny of the invention is described in terms of length, height, and scale indicators that differet engineer will immediately understand. However, engineered drawings are not the only kind of technical drawings useful to an inventor. Another commonly used drawing is known as the cutaway drawing shown below.
The main purpose of the cutaway drawing is displaying your invention in 3D form — rather than flattened out — but opaquely, so that the inner workings of the invention are still visible. Drafting a cutaway drawing enables an engineer or manufacturer to get a better picture of how the invention should look in its finished state.
Still another kind of technical drawing that often proves valuable to inventors is the exploded view drawing. For inventions that contain a lot of moving or inter-locking parts such as the gear pump pictured belowan exploded view drawing captures the interconnectedness of these components and the exact way in which they fit together to form your completed invention. Without an exploded view drawing, you are left explaining these complicated inter-relationships verbally, which rarely knds the subtle nuances of how it all has to work in practice.
CBLM_Identifying Different Kinds of Technical Drawings
In addition to physically creating your invention, technical drawings come in handy when filing for patent protection. Another example of draftsman jobs are civil draftsmen.
These professionals work with different kinds of maps. They have expertise in reading and drawing relief maps and topographical maps of different areas. A trained civil draftsman may find work on projects for
drawing municipalities and companies involved with making regional planning projects a reality.
Anyone interested in working as a mechanical draftsman will be involved with making drawings of various machine systems as directed by his or her employer. Most people who are drawing this type of work are using a Computer Aided Design CAD program to develop original drawings or make updates to existing ones. The mechanical draftsman will likely be working under the direction of a design engineer or a senior designer.
People who start off working in entry-level draftsman jobs can eventually qualify for supervisory roles where they are responsible for leading and coordinating the work of a group of workers. A combination of a few years of practical experience and further courses to give the individual skills they need to step into a management role are needed.
