One thing that sets construction drawings apart from simple illustrations is that construction plans are drawn to scale. Here, Jim shows how to find the scale information on each drawing, and demonstrates how to measure dimensions on construction drawings.
- [Narrator] One of the things…that sets construction drawings apart…from simple illustrations…is the fact that they are drawn to scale.…This means that every line on the page…that represents an element in the building…like a wall or a door or a window…can be measured on the page itself…to find out what size that's going to be in real life.…The designer simply take in the real-life structure…and shrunk it down to size…while keeping everything in proportion.…Now, this allows us to do things…like measure the size of rooms or driveways…or anything else on the project right on the sheet itself.…
All we need to know in order to make this work…is how much the designer has shrunk things down…and we should always be able to find this information…on each page in a legend called the scale.…Let's take a look at this by going to our digital drawings…and taking a look at where the scale appears…on different sheets.…So I'm going to go ahead and click to our second page…which is our site plan.…Now, if I zoom in to the bottom left corner,…
In this course, learn how to read construction drawings. Jim Rogers helps you acquire this important skillset by taking you through the different components that make up construction plans, and helping you understand the language of construction drawings. He covers types of views, highlights different kinds of construction drawings—including architectural drawings, electrical drawings, and plumbing drawings—explains how to read general notes, and more.
