Orthographic projection also sometimes known as orthogonal projection is a projection system in which three-dimensional figure is drawn to several two-dimensional sections. In this system parallel lines are drawn from projection plane which are orthogonal to projection plane. These parallel lines are used for preparation of drawing of object. In such drawing it is assumed … Read more
Free hand sketching is the most basic element of engineering drawing. As the name suggests, drawings are made with a free hand without any instrument. Therefore, free hand sketching is the simplest and quickest way to transfer one’s ideas on to a piece of paper. Engineers use this approach at rudimentary stages of a project … Read more

The standard cinder blocks dimension most commonly used in United States is 8x8x16 in inches. That’s the nominal size and the actual specified size is less by 3/8 inches in thickness because of the mortar joint. The actual dimension is 7 5/8” x 7 5/8” x 15 5/8”. In a typical 8x8x16 dimension of a … Read more
Crawlspace foundations are a pretty common type of foundations for homes in America. Unlike slab or slab-at-grade foundations, it brings inherent benefits like protection from flooding. It offers flexibility during an earthquake or seismic activity. At the same time, you can face problems with a crawlspace. If you won’t control the moisture penetration, you can … Read more
Understanding the concept of setting time of cement is important while handling concrete like transporting, placing, and compaction. Setting of cement is relevant to concepts like hydration process and hardening. In normal circumstances, when you are using concrete, you want it in a workable or flow-able condition for pouring in desired shape. That’s because it … Read more
Finding the overall cost of fence installation project is quite a daunting task. It involves knowing the average costs and finding the dimensions for your home. If you’re lucky to have a simple lot, finding dimensions might be a simple step but knowing average cost is a whole new ball game. But with our fence … Read more
Plane table survey is a graphic method of surveying in which field work and plotting are done simultaneously. It is the fastest and easiest method of surveying where great accuracy is not a concern. It is useful for filling in details between stations fixed by other methods. In plane table survey, no heavy and costly … Read more
