Join Scott Onstott for an in-depth discussion in this video Drawing strategies, part of Creating an Architectural Drawing with AutoCAD 2013.
In this lesson, we will begin drawing the cottage floor plan from the measurements given in the attached image. In the course of drawing, you will see the strategies I use to solve the geometric challenges presented in the sketch. Open the Cottage 2 project file, and click the Line tool. Click the right end point of the existing red line and zoom in. With Ortho on, move the cursor down and type 71. Move the cursor to the right and type 49. I'm going to move these lines up because the sketch is a little bit off from what I'm drawing, and I think it will become confusing if I try to draw over this pencil sketch.
So, I'm going to zoom out, type M for move, make a window around the three lines, and move them up. Then I'll zoom in a little closer here, and to get an accurate zoom I'll type Z Enter Enter, and drag the mouse up or down to do a real-time zoom. Then I can get the zoom level just where I want it. Press Enter to end the command. Then I'm going to assume that the walls are about five-inches thick.
I'll move the cursor up from that last point that I clicked and type 5 Enter. I'll draw a line over this way some arbitrary distance, and then I'll use the offset tool with a distance of five inches, Enter. I'll select this line and click on the right. I'll select this line and click above it to offset those lines. I'll then select this upper line and move its script over some orbitary distance to represent the entire cottage wall. Press Esc to deselect.
Click the line tool, and draw a line down. It looks like the dimension is 39 and a half. I'll move it over five inches and draw it up. Then I'll use the fillet tool, and I'll set the radius to zero and click these two lines to join them together into a corner. I will repeat that and join these two lines together as well. Down here at the pocket door, it looks like the opening is 27 and a quarter.
I'll use Offset, and I'll type 27.25 Enter. Select this line and click on right side. Then I'll click another line from here over 38 inches and then up. Again, Offset five and offset these lines, and then fillet, F enter. Click the two lines you want to join. Now, up here I need to draw an another line to connect the dots and another line going across here some distance. Now here is an example where the measurements looks like little of a little bit.
You see there is a mismatch here. And this is typical of dimensions taken in the field. What I need to do is make a decision about what I am going to trust. I think this is probably too thick. So what I'm going to do is erase it. Use Fillet to join these two lines precisely. Draw a line from here, over. And then Fill It these two lines together. So I have eliminated that slight mismatch.
Now I'm just going to zoom out a bit, and let's draw on this window opening. I'll draw a line from this corner up to be perpendicular to the top line, and then I'll type M for move, Enter, L for last object created, Enter, Enter again. Click a point, move to the left and type 4.25. Than Offset 22 and move this over like that.
This represents a window, and later on I'll come in and draw things on different layers. Right now just focus on the wall layer. Okay, down here, we have a counter that's 49 inches from the wall, so the easiest way to get that is to use the Offset command and offset this line over that distance. We also see in the sketch that this counter is 49 inches up from this wall. So, again, I'll use Offset, Enter, click, click.
And then, I can move this over, horizontally and then fillet with two lines into a corner. Now, right here it says 42 and a half from the counter to the wall. So I'll offset, type 42.5 Enter and offset that over. Hit Enter, Enter, and then type 5 Enter to set a different offset distance, and then offset that line over.
And then I'll use Fillet to fillet these lines into corners. I'll use Stretch, and stretch these two end points down. I don't know how far yet, but I'm just going to go down some arbitrary distance. It looks like we have another window opening here, and it is fifteen and a quarter from the top wall. So I will offset 15.25. This line down. And now I need to move that over.
I'll just move it through the wall like that. Then I'll use Trim. I'll select these two objects as cutting edges, Enter. And click here and here to trim away the line. Then I will offset 47 inches. Move that down. And it's getting hard to see here, so I think what I need to do now is clip the image, so I don't have the whole image on the screen.
To do that, go to the Insert tab, and click Clip in the Reference panel. Select the image, and then press Enter to accept the default option, which is New Boundary. And then press Enter again to use a rectangular boundary. Then you need to draw a rectangle over the image to represent where you're going to clip. The whole image is still there, but I'm hiding the rest of it so that I can have a little bit more room on the screen to work.
I will move all of these objects that I have drawn over here, and I'll turn off Ortho and move them above here so I can see what I am doing a little bit better. Then I'll use Offset. And I'll offset this line down 49 and 3 quarters. So I'll type in 49.75 Enter. Offset that down. And again, Enter Enter. Type 46.75 to represent this window opening down here. And then offset again five inches to represent the thickness of the wall, and then I am going to stretch these two lines over. And I need to use Ortho to make sure I do that horizontally, and then I will fillet these two sets of lines together to make a corner. It looks like I also need a line from here to go perpendicular, to represent that window.
Let's draw in more of the counters in the kitchen. Now, right here we have a dimension that says 15, 5 and 3 quarters. I think that's the width of the counter, offset 15.75 Enter. Click this wall, and offset to the left. I will fillet with these two lines together. And then we also have a dimension 63 and a half. I will offset, 63.5 Enter, and bring this line down.
Again I can fillet these two together, to form a corner. The stove looks like it's about 30 inches wide, so I will offset 30, Enter, and move this down. And I will draw another line, here, down. It looks like 27 and a half. And then we have a line that goes at a 45 degree angle that's 15 inches long, so for that, I need to turn on Polar and set my angle to 45 degrees. Draw a line from here down, and I'll type in 15, and then I'll move over horizontally and type 16.25 and then draw it down here perpendicular. Now, I need to draw in another line here down to the perpendicular to the lower line and then offset it by typing O Enter 46.5.
Then I'll click this line and then click on the left side. Press Enter Enter to end and restart the offset command. Type 7.25 Enter and then offset this line over. Again, Enter Enter, 27.5 Enter. And then offset this line over. I'll use the Trim command. Press Enter to select everything, and then do a crossing window to cut away that door opening.
So to summarize, you have seen how I am using the line, offset, fillet, and stretch tools to lay out the walls on the cottage floor plan. Don't worry if you are not as fast as I am at drawing. That is to be expected. Your drawing speed will increase as you gain more experience with AutoCAD.
