After sketching the drawings on paper, I had to show my ideas on AutoCad in order to get the proper measurements for my design. This is done so that the construction of the model will be more precise/easier to make. Of course, the measurements are to scale to show inches and feet- architectural measurements.
For the drawings on AutoCad, I need to show everything from a birds-eye view; showing the first and second floors of my cabin. Also, elevations are required to show the side/front of the cabin. In addition, I will include a site plan to show what’s happening around my cabin (to include a river, some rocks, my pico-hydro and wind turbine generators and more).
I didn’t include many hatches to the AutoCad drawing (in AutoCad, hatching is used to add a texture/design to a closed shape). This was so that I wouldn’t get confused/distracted by my design. This also makes my design look really simple; which is good in that it gives me a better understanding of what I’m building, but bad in that the AutoCad design itself looks unappealing.
As said before in my previous blogs, I have to work on a 1000 square foot bungalow. I’ve already finished my thumbnail and rough designs for the bungalow, so now all I have to do is to apply it onto AutoCAD.
I chose architectural units as inches, because that’s how most buildings are measured in; inches. Also, this way the drawing would be easier to draw because it’s would follow every unit in inches for the floor plan from the birds-eye-view (because inches are split into sixteenths and feet are split in twelfth). I wonder why buildings aren’t measured in centimetres and metres? THAT WOULD BE SO MUCH EASIER FOR BEGINNERS LIKE ME! Alright: I just Googled the answer to this, and it’s because the rest of the world measures their merchandise in inches, and it would be confusing for everyone else if they adopted the metric system (I guess it’s like why scientists have such big names for everything; so that it’s a universal name for all languages).
As in my rough drawing, the outer walls in the AutoCAD floor plan are a foot in width and the inner walls are half a foot in width. Instead of using the line thickness button, I decided to draw double lines (two lines) for all of my walls so that it won’t interfere with the other fixtures in the house. In addition, in the AutoCAD that I’m using, I am given a ton of pre-made fixtures like toilets and bathtubs and sinks, which will all just add to the looks of the final product.
Right now, I have to design a 1000 square foot bungalow (house containing only one floor). In a sense, the bungalow design will be similar to that of a condominium; however unlike condominiums, bungalows have a rooftop, a driveway, a yard, a foundation, a porch, a basement, stairs, a garage, 3 outside-doors (for the entrance, for the backyard and for the garage), windows located on all the outside walls of the house and possibly a chimney with a furnace. In addition, because the bungalow contains a basement; a laundry room/a separate room for the HVAC is not necessary; therefore allowing much more space than in the previous 800 square foot condominium that I had to design (at twice the price that is).
For now, the rough design of the bungalow that I created contains all of the compulsory rooms including a kitchen, a bathroom, a master bedrooms, a living room, a kitchen and stairs leading to the basement. Also, a guest room and a powder room was added. For roofing ideas, I chose to do an intersecting roof, as it works best for the shape of the bungalow that I am doing, and I’m assuming the bungalows are meant for Canadians (and in Canada, there is A LOT of snow, so roof types like the butterfly roof or a flat roof aren’t the best ideas). The basement is 8 feet high, and the dimensions of my stairs are 6 inches high, 9 inches long in width and 36 inches lengthwise; so my stairs are probably going to bend in a “U” shape to reduce the amount of space that I’m using. To calculate the amount of room the stairs took on the first floor (to the basement), I had to first find out the minimum number of stairs needed that will allow enough headroom (so when someone walks down the stairs, they won’t hit themselves on the head). This number (minimum number of stairs for headroom) multiplied by each stairs’ area is equal to the amount of space that needs to be taken on the first floor. For me, I needed 9 stairs to allow enough headroom, so 9 x (6 x 9) = 486, hence I will need 486 square inches (or 40.5 square feet) of space on my first floor to put in the minimum number of stairs.
My duty is to only draw the stairs from a birds-eye view, so for more help go to: http://daveosborne.com/dave/articles/stair-calculator.php
I did a short tutorial on how to use AutoCAD, so now I understand/remember a little more about it; just a little less than the basics. So now, I can draw lines by clicking the “line box” and then setting in coordinates from one end of the line to the other. I can hatch things by clicking the “hatch box” and selecting a face of what I drew to be hatched. AutoCAD is a VERY precise program that professional architects use to draw building designs or any other designs, so there are probably many other ways to hatch or draw lines in it, such as drawing lines based on its length and angle. It would be useful to know all of these different methods of doing things, depending on the different situations given (like quickly calculating the length of edges or the angle without the use of a pencil and paper for trigonometry). In addition to this, there are also many 3-D techniques that must be learned from AutoCAD; however I don’t think I’ll be learning how to do that in the near future…
In my opinion, I think AutoCAD is somewhat easy to understand (the beginners tutourial, though) and I would understand why it would be suitable for professional architects/designers to use it. Often, I mess up on what I do in AutoCAD; hence I have to start over again. However, as I continued using it, I got to understand more of it with some help from my peers. So I guess AutoCAD’s alright, and I would suggest anyone who wants to proceed into architecture and design to purchase it and learn how to use it.
