Basic Drawing Skills / Units

Subtitles of the Movie

In this drawing we're going to set the drawing to use architectural units which is an Imperial unit measurement. So we're going to be working in feet and inches instead of a decimal unit such as millimeters or meters and all we're going to do is we're going to use the Dynamic Input Interface to sketch the outline of a simple floor plan. Now to set the unit type, the easy way to do this is to just type the word units like so and press Enter. That will bring up the units Dialog Box. You can also, if I just cancel this, go to the Tools Tab, and it's available on the Drawing Utilities Panel on the ribbon here, units. Now what we're going to do, we're going to set our length and our angle settings and draw the objects on the drawing. So, in this case, we're going to select architectural as our units there. Notice it goes to feet and inches and the precision there we're going to go to one eighths of an inch like so. Now the angle itself we can leave that at decimal degrees. That's absolutely no problem at all and you'll notice that the Insertion Scale has also gone to inches here. I'm going to OK that now and in the drawing now when I draw anything I'll be using a length unit of inches to an accuracy of one eighth of an inch. So we're going to click on the line command now. So I'm going to go back to my Home Tab and click on the Line Command here in the Draw Panel and I'm going to specify the first point. Now notice the Dynamic Input Read out is giving me feet and inches now. So the coordinate that I'm going to input is 10 feet by 10 feet. So I type in 10 like so, hit the Tab key or the comma key and type on ten again and press Enter. That give me a coordinate there of 10 feet by 10 feet. You might notice it's slightly off the screen there. So all I do is I pan like so, and you can see now that coordinate at the end of the line as I move the mouse. That sometimes happens with drawings, you do get a view or a magnification or a Zoom setting where you're off the screen slightly. Just pan using the wheel on the mouse. So now I'm going to move the cursor to the right along the zero line like so, and I'm going to type in a distance there of six feet and eight inches. So I type in six and then the apostrophe like so and then a -and then eight and then inches. I then press enter and that draws my line of six feet eight inches, Now for the next point, I'm going to move the cursor downwards and to the right like so. I'm just going to pan outwards a little bit here so you've got a bit more clarity and I'm going to drag it down like that and I want the line itself to be 2 feet 4.25 inches. So I'm going to type in there 2 like so and then the apostrophe again and then 4 and of course inches. Now remember a -like that and that way AutoCAD will distinguish feet and inches. I then I'm going to hit the Tab Key and the angle I want that drawn at is 45 degrees and then hit the Tab Key again and you'll see that, that line now if I left click has come down at 45 degrees. I'm then going to move to the right again, here like so and this time I'm going to type in 4 in the Distance Box, again with the apostrophe symbol and press Enter and there's my line that's four feet long. What I'm going to do now is go upwards now like this, I want to go up at this angle here and I'm going to type in 2 feet again like so and this time I want 4 and a quarter inches, so that's a -and I can type in 4 like so and then -1 /4, press the Tab Key, it even picks up that, that's 2 feet four and a quarter inches. And then the angle this time is going to be 45 degrees again, press the Tab and you can see now when I left click that, that line has gone but 45 degrees at that distance setting. So you can see there that I'm using units in a different way. I'm using feet and inches with the architectural setting. I'm using Imperial measurement instead of Metric measurement. So now I can draw a line this way like so, horizontally along the 0 line and I'm going to type in there 45 feet with a -and then 8 inches like so. I press Enter and that line goes along there like so. It's exactly the same as using Metric measurement, its no different your just using a different unit setting. So I'm going to go vertically upwards now like this and I want a distance there of 15 feet and 3 inches. So I'm going to go up this way like so and I want 15, again the apostrophe, -and then 3 inches. Then I press Enter and there's my line. Now what I can do now, I can cheat. I've got my Object Snap Tracking On so I can hover over this point here, I can hover over this point here and as I drag along there's my intersection and I left click. I now know that, that is an exact corner, I go down to this end point snap here, left click and Enter finish. That's how you change your units, that's how you use different units and also different conventions of measurement such as Metric and Imperial.
