Projections First angle and third angle projection methods are acceptable. The symbol identifying the type of projection used should be placed in a space provided in the drawing block Views Using Reference Arrows. Principal View The principal view on which all of the other views are based should be selected as being the most informative. Lines Used on Drawings.. Line Thicknesses Two thicknesses of line should be used on a drawing. Line spacing The minimum space between parallel lines should always be greater than twice the thickness of the heaviest line. Leader Lines Leader Lines terminate Lettering Lettering should all be in capitals and underlining should be avoided. With the normal paper in landscape orientation and the title block on the bottom right and side, notes to be parallel with the bottom edge. General notes shall be normally grouped together. The minimum letter sizes are specified to meet the requirements of reading microfilm copies of drawings. Hatching

How to read engineering drawings – a simple guide | Make UK
You don’t have to be an engineer to be able to read engineering drawings, but learning how to read engineering drawings can give you the perspective of an engineer, which can be a significant advantage in your work. The ability to interpret technical drawings accurately helps you make informed decisions and communicate more effectively on projects. What is an engineering drawing? Engineering drawings (aka technical drawings) are a blueprint that provides clarity on all the critical information and requirements needed to manufacture an item or product. It is more than simply a drawing; it is a graphical language that communicates the true length and precise details about objects to effectively communicate ideas and information. Why not just use a 3D model over a technical drawing? Unlike a 3D model, an engineering drawing offers a lot more specific information and requirements, including: DimensionsGeometry TolerancesMaterial typeFinishHardware Information blocks Title block Revision block Lines

One of the simultaneously good and difficult things about oil paint is that it dries slowly. Storing oil paintings as they dry is always something of an issue. Plein air painters, in particular, who often produce a lot of small paintings in a relatively short time frame, are faced with the question of how to arrange their panels as they dry. I came across a nicely done and simple-to-construct plan for a DIY drying rack by plein air painter Matthew Lee, which he was kind enough to share with the community on Wet Canvas. In his version, Lee uses pegboard and dowels to make racks that fit within the shelves of a store-bought metal shelving unit, dividing the space into panel holders of varying heights on four shelves. In my case, I used his idea to make a more modest, single, free-standing rack just for small panels, at a size that would fit onto a bookshelf in my small studio space. He used pegboard and 1/4″ dowels, which in his case seemed to fit well through the pegboard.
Engineering Drawings
by Ernesto E. Blanco, David Gordon Wilson, Sherondalyn Johnson, and LaTaunynia Flemings Drawing Handout Index Introduction One of the best ways to communicate one's ideas is through some form of picture or drawing. We will treat "sketching" and "drawing" as one. This is just an introduction. We hope you like the object in Figure 1, because you'll be seeing a lot of it. Isometric Drawing The representation of the object in figure 2 is called an isometric drawing. Any engineering drawing should show everything: a complete understanding of the object should be possible from the drawing. Orthographic or Multiview Drawing Imagine that you have an object suspended by transparent threads inside a glass box, as in figure 3. Then draw the object on each of three faces as seen from that direction. Figure 5 shows how the three views appear on a piece of paper after unfolding the box. Which views should one choose for a multiview drawing? Dimensioning Sectioning Drawing Tools "Assembly" Drawings

What do we mean by perspective?
Organization: Alexa Crawls Starting in 1996, Alexa Internet has been donating their crawl data to the Internet Archive. Flowing in every day, these data are added to the Wayback Machine after an embargo period. The Wayback Machine - Perspective drawings show objects as you would see them in the real world - in three dimensional view. Have a look at the perspective drawing below. The lines of sight in a perspective drawing can be projected to a vanishing point in the distance. Perspective drawings are a 3D representation of an object but the proportions are not true – they are distorted to give the perception of depth. Disadvantages of a perspective drawing Only three sides of a component are shown. Due to these disadvantages, engineering drawings are rarely drawn in perspective projection.
