AutoCAD Tutorials for free, 2012 2013 Lessons, Videos - a Complete Course If you do not have a copy of AutoCAD, you can download a 30 day evaluation copy from Autodesk. Follow this link, or go directly to their website. You will be downloading AutoCAD 2014 and it will work fine with these tutorials. You can also try other CAD programs like ZWCAD, which are less expensive alternatives. Here are complete lessons divided into 4 levels of learning. Each Level is one section that builds on the previous. Many lessons have videos with narration to explain in detail some of the concepts. SolidComponents – A free 2D and 3D CAD library Dimensions on drawings - Cabinet Oblique and Cavalier Oblique. Drawing guides - Radius and radii dimensioning - Positioning of dimensions on Engineering and technical drawings for high school students at KS3, KS4 and KS5 - Design & Technology On The Web - ‘Cabinet Oblique’ In Cabinet oblique the scale (depth) is halved whilst in Cavalier oblique the depth scale is the same as in the X and Y directions. One remaining drawing conventions is Oblique drawing – In this convention the angles used are 45 degrees and 90 degrees. The only difference between the two named styles is in the scale of the dimension going away from the viewer. This first example is Cavalier Oblique and shows the full scale (1:1) in the axis This drawing (shown to the left) is symmetric about the horizontal centre-line. Centre-lines are chain-dotted and are used for symmetric objects, and also for showing the centre of circles and holes. Engineering Drawing and Sketching for GCSE A Simple Guide to Dimensions ... ‘Oblique’ Drawing ‘Cavalier Oblique’ and ‘Cabinet Oblique’ If you need a mnemonic to remember the correct way round for these two styles – ................ things always look tidier in cabinets !

A Simple Guide: 12 steps to Master AutoCAD Many people think that learning AutoCAD is hard. It’s not. Yes, there are many things to learn. But using AutoCAD is not difficult. The key is you need to learn one step at a time. This article is not a tutorial, but what do you need to achieve before you can master AutoCAD. 1. © tarasov_vl – Fotolia.com First, you have to be familiar with the interface. AutoCAD Interface AutoCAD interface now is easier for new users. Navigate the drawing Now try to open any drawing. Now you can start to create a new drawing and try to draw. The rule is: create a new drawing using appropriate template. 2. After you get familiar with AutoCAD interface and its navigation tools, now it’s time for you to learn how to use drawing tools. How AutoCAD tools work Drawing tools are very easy to use. Command line is just like a road sign; it will guide you, so you don’t get lost. Command: _line Specify first point: Specify next point or [Undo]: Specify next point or [Undo]: Specify next point or [Close/Undo]: 3. 4. 5.

Can we learn from English crop pictures how to escape into space, before melting of the North Pole ice triggers a runaway greenhouse effect? By Horqce Drew Can we learn from English crop pictures how to escape into space, before melting of the North Pole ice triggers a runaway greenhouse effect? Part VI: Dozens of different crop pictures, presented to us over 20 years, show the schematic “blueprints” needed to make novel magnetic energy devices Appendix. Current passing through a magnet induces a torque and counter-torque in local space, relative to a rotationally-constant magnetic field For the past 20 years, or possibly since the time of Newton, strange and unexplained patterns have been appearing in English or European fields (see time2012x or time2012y). In the first five parts of this series, we studied some of the field patterns or “crop circles” which encode for novel electrical or magnetic devices (see time2012r or time2012s or time2012t or ime2012wl or fringe2012a). While I was writing this, the matter has assumed some urgency. Some people ask, “Why are crop circles so hard to understand?” Further examples are shown below:

Isometric Drawing.  Isometric drawing is another way of presenting designs/drawings in three dimensions. The example opposite has been drawn with a 30 degree set square. Designs are always drawn at 30 degrees in isometric projection. 1. 2. 3.Draw the two sides in place. 4. CLICK here for more information on Oblique Drawing. Question 1. Click HERE to download an isometric grid to assist with isometric drawing. 1.An orthographic drawing showing the front and side view of a computer diskette is shown below. Using you isometric grid, overlay a piece of A4 paper and complete the drawing shown below. Add appropriate shade/colour. Use the grid dowloaded above again overlay a piece of A4 paper to help you draw an isometric presentation of a simple mobile phone . Add the text and numbers but remember to print in isometric projection. Add appropriate shade and colour. Question 2. You have already made an ORTHOGONAL drawing of the camera. Draw an ISOMETRIC drawing of the camera. Question 3.

JMcIntyre - TDJ3M_Views_and_Sketching Daily Calendar | Views & Sketching | Material Selection | Mechanical Design | Industrial Design | Architectural Design | Summative In a non-perspective drawing there are no vanishing points therefore lines that disappear into the distance have to be treated in one of two ways - a) they don't exist (an orthographic or elevation) or b) they exist, but no perspective will be applied to them (oblique and isometric view). We create these orthographic drawings because you can take a designed part, draw it, dimension it and then give all the needed information to the manufacturer. In a 3D environment dimensions become burdensome. All objects of course are 3 dimensional and when displaying them in a 2D fashion we must include features not visible from the 2D viewer's angle (straight on in the case of an orthographic drawing, or from an edge-view from the case of a oblique or isometric view). Orthographic / elevation view Oblique view Isometric View A more visual explanation can be seen here.

For Autodesk, a Step Into a Nanoscale World “Project Cyborg” offers services like molecular modeling and simulation. Autodesk, a quirky software start-up in Marin County, north of San Francisco, rose to prominence in the early 1980s because of AutoCAD, its computer-aided design program that was intended for use on personal computers. Over the next decade, AutoCAD became the standard design tool for architects and engineers. This week at the TED conference in Long Beach, Calif., the company will take the first public step toward translating its computer design approach, which has since spilled over from Hollywood to the Maker movement, into the emerging nanoscale world of synthetic biology and materials. For the last two years, a small group of software engineers and molecular biologists have been developing a software system for designing at the molecular level at the company’s research laboratory in downtown San Francisco. The company has quietly begun working with a small group of molecular biologists in the last year.

Pro/ENGINEER Lesson #8 - Creating a Drawing Dept. of Mechanical Engineering University of Alberta Oops! Wrong Lesson - return to main tutorial page. Overview of this Lesson The primary form of design documentation is the engineering drawing. In this lesson, we are going to create drawings of two parts: an L-bracket support and a pulley. Here are links to and brief descriptions of the two sections of this lesson: The L-Bracket Creating the part Creating the drawing selecting the sheet creating the views adding dimensions cosmetic changes Changing the part/drawing Sending the drawing to the printer The Pulley Creating the part Creating the drawing selecting the sheet creating a section view adding dimensions cosmetic changes Section 1: The L-Bracket Creating the Part Create the part shown in the figure below using the part name lbrack.
