Join Scott Onstott for an in-depth discussion in this video Starting your project, part of Creating an Architectural Drawing with AutoCAD 2013.
In this project you will draw simple floor plan of a cottage that I sketched on site. In this lesson you will attach a scanned image of the sketch in AutoCAD, and then configure the drawing units, according to the dimensions given. You will also create a few layers to represent the different types of objects represented in the sketch. Then you will scale the image to its approximate real world size to provide a basis for the drawing project. Go ahead and open the cottage one project file which is currently blink, and then type IM for image and press Enter.
This opens the external references palette, then open this drop down menu and choose attach image. Select cottage sketch from the project explanation one folder and click Open. Let's leave relative path selected here, because AutoCAD will enable to locate the image. Because it's in the same folder as the cottage one drawing file. If the image was in the different folder, you would have to select full path and the entire path would be stored in the file.
However, if you at some point in the future moved into the drawing file or the image in AutoCAD wouldn't be able to locate the image reference. So the safest approach really is to, store your images in the same folder as your drawing files, and leave relative path selected. In that way you can move the folder to a different location, and AutoCAD will still be able to find the image. Now we have some options, here, about how we want to insert the image. Let's leave Specify Onscreen checked for both Insertion Point and Scale, so that we can interactively choose where we want to put the image, and how big we want to make it.
But we'll leave this unchecked. Because the image will come in at an angle of zero degrees, and that will be fine. Click Okay, and then click a point down here in the lower left corner, move the cursor over to scale the image up, and click again. Incidentally, if you want to turn off the image, you can right-click Cartridge Sketch here in the file references area and choose Unload. The image frame remains but the sketch is hidden, you can turn it back on by right clicking again and choose Reload. If you detach the image, it will actually delete this reference. So, let's click Reload and then close the External References palette. Let's zoom in and see what we have here.
This was a pencil sketch that I made on site. As I pan the sketch, you'll see that it disappears temporarily. Notice that all the dimensions given are in numbers with fractions. These are in inches. So lets choose the appropriate units to represent this, type un, Enter. Architectural units could work, because they support feet in inches. However you will notice that there no feet given in these dimensions, that was because it was easier to measure the site with the tape measure and just read off the number of inches on the tape without having to calculate how many feet and how many inches it was.
So this drawing could just as well be a metric drawing perhaps these might be centimetres Although they might be larger numbers. If you were using metric, you should probably choose decimal units, because you're more likely to choose 27.25 centimeters, rather than, using a fraction. But in this case, I'm going to choose fractional units, because I am matching the units up to what the sketch information shows me.
I have 4 inches with fractions so fractional units will be the best choice. I leave inches set as the instruction scale and tehn click okay. Then I will double-click the mouse wheel to Zoom extents. Let's create a few layers to represent the different types of information in this drawing. On the Layers panel you'll find a button right here in the upper left-hand corner called Layer Properties, click it to open the Layer Properties Manager and then click right here to create a new layer.
Every drawing has layer zero by default, but you can create any number of layers to represent thr types of objects in your drawing. Type Wall and press Enter, press Enter again to create another layer. Type door, and press Enter twice. How about Counter? We have some of those. I'll press Enter again, and I'll type Window. Press Enter two more times. Type Stairs.
We also have some plumbing fixtures and appliances, but I'll put those on the same layer. I'll call this layer fixtures-appliances. Enter. Now to differentiate the layers on screen, it's helpful to choose different colors. So I'll click right here on this color swatch, on the wall layer and that opens the select color dialog box. I'll choose red and click OK.
The layer properties manager went to auto- hide mode. So I have to go back here and hover the mouse over the title bar to show it to me again. I'll just click this button here to turn off auto hide. So that this pallet remains open. I'll click here, and choose yellow for the door. And then click here, choose green for the counter.
I'll click here and I'll chose cyan for the window. The stairs can be blue, and the fixtures and the appliances will be magenta. Okay, we've set up the layers we need for the sketch. The last step is to scale that sketch to the approximate real world size. I'll close the layer properties manager, and let's identify the longest dimension in the drawing. It appears to be this number up here, 172.
I'll zoom in there, and then set the walls layer current. To do that, open this drop-down on the Layers panel and choose Wall. That makes it the current layer so that anything I draw now, will be on that layer. Click the Line tool on the Draw panel. And then, click the corner of the wall here, turn on Ortho and draw a line horizontally over here.
You see how the sketch is pretty rough? It doesn't really follow the horizontal line at all. But we're going to do our best and see if we can approximate the real world size of this wall. So, I clicked there and I'll press enter to complete the line command. Now, I'm going to zoom out a bit by rotating the mouse wheel and I'll use the scale command and I want to scale up both the image by selecting its frame, and the red line that I just draw. So select both objects, press enter.
The base point of the scale, will be the left endpoint of the wall. Unable to snap to that because I have Running endpoint snap-on down here. I'll click right there to specify the base point for the scale, and then I'll use the reference option. The reference link is unknown, but I can specify it graphically on the screen. By clicking two points.
So, I'll click this same end point and then the opposite point over here and then the new length is going to be 172. So, I'll type that in and press enter. Now, the sketch got much bigger and I need to zoom extents to see it. And it looks the same, but it's a different scale. You can verify that by using the Measure tool right here on the Utilities panel, and click the two endpoints of the red line, and you'll see that it is 172 inches.
So, now the sketch is to real world scale, and let's go ahead and save it as cottage2.dwg. So I will click the Save As button on the quick access tool bar and I will go into the My file sub folder and just change this to cottage2, and click Save. In summary you learned how to attach an image to drawing, and how to scale that image to its approximate real world size. You said the units appropriately and also created layers and assigned colors to them.
