Robert+B-3A

Welcome to my CAD Drafting page

In Assignment A I learned how to turn the grid on, and how to use snap. This assignment taught me how to draw basic lines, a skill I will use a lot during this course. I see no real life application to this other than wood working or making templates. I miscounted on one of my shapes; this made the whole drawing incorrect and had to be re-done. I successfully copied what was in the book, simply by following directions.

In Assignment B I did the same as in Assignment A, I recreated the shape in the book by counting squares and drawing lines. I learned how to connect my lines at a specific point. Again, I see no real life application, maybe wood working. The top drawing is not symmetrical, I thought it was supposed to be symmetrical, but after further examination I discovered that the diagonal lines had different slopes. I successfully fixed my problem; in the future I will measure twice and draw once.

In this Assignment C I am introduced to the web tool. I wish there were more drawings that required the use of this really cool feature, but there is not. This type or skills would be useful if I were designing video games. There were many problems drawing these shapes, mostly using the web tool. All I had to do was hit the undo button and try again until I got it right. I successfully finished these drawings.

In Assignment D I stated with a pentagon that I created using one of the tools. I also created an illusion with lines; the drawing on the right seems to be overlapping. Drawing a 2-D object to make it look like a 3-D object will help me with other drawings in this course. You could use these skills to create illusory images. I deleted the wrong line a couple of time, I simply hit undo, and try again. I successfully taught myself how to use the trim tools better.

In Assignment E did the same overlapping technique that I used in Assignment E, only a different shape. I bettered myself with the parallel line tool, which is a vary useful tool. The parallel line tool could be used in creating grids, or patterns. I had trouble with the delete tool, I kept deleting the wrong line, I simple hit undo and tried again. I am successful because I created a 2-D drawing look 3-D.

In Assignment F I started learning about angles, labeling, and mirroring. All these tools will help me a lot in the future; labeling your work dimensions is important because it can help recreate this shape without measuring it first to find all the dimensions. The mirror tool gave me a lot of trouble, nobody was here to help me so I had to figure it out on my own. I was successful because I can use this mirror tool in the future if I get a symmetrical shape and I feel like being lazy. On the sheering blank I had many difficulties, mostly with labeling, however Mr. Kevin Sarle gave the idea to use different color, shape, and size lines. I can use this skill in the future with this class In Assignment G I worked with angles, the angle line tool was sort of tricky to learn to use, but by practicing it becomes easier. Correctly using angles in the real world can save you a lot of time, simply by knowing which angle goes in what direction. A problem that I ran into was I forgot to use the angle measure, instead I used a vertical line measure, I thought my work was wrong even though it was not wrong. However I realized my mistake and quickly an easily fixed it. Instead of deleting everything and starting over, I was able to fix my mistake, I saved myself a lot of time, and for that I am successful.

In Assignment H I am introduced to a new shape, the circle. Leaning how to draw circles and semi circles is a very important skill to know in future drawings. But I thing knowing how to precisely remove certain sections of that circle is more important. Drawing a circle freehand is very difficult, almost impossible. Using computer and other aids help out a lot. It took me forever to learn how to delete parts of the circle, because the circle is one continuous line. I had to ask Kevin Sarle for help. I was successful because I was able to reconstruct these images with little instructions from the book.

In assignment I one forth of the image with measurements was given, I was told to reproduce the whole image. I created the forth of the image and did mirror imaging to flip the design to create a symmetrical image. The mirror tool is just a lazy way to draw things. In The real world mirrors are used to show identical flipped images. There were no problems with did drawing, all went well.

Assignment J may look very complicated from a glance, but rotating tools make life easy. All I had to do was create part of the image and use the 360 degree mirror tool. The friction plate that I created reminds me of a gear, and I would imagine that mirror tools like the one I used could be used to create such gears. The inner gear part of the friction plate was very difficult to make, I couldn’t find any easy way to make it. Even the teacher was stumped on how the book expected me to create it. We had to get a little creative to do that particular piece.

Assignment K has two drawings that were very different from each other. In the transformer mask I was doing basic drawing, only the dimensions were very complicated. The initials were very simple at first but the difficulty was increased when I was asked to go 3-D. 3-Dementional drawing are used for millions of things. The 3-D drawing was surprisingly easy, but the transformer mask took me a couple of classes to make on account of its many dimensions. Some dimensions were not given, some simple math was used to figure them out.

In assignment L, I am working again with 3-D shapes. I first created half of a 2-D drawing and used a tool that rotated that drawing 360 degrees on a specific axis. This tool helps when creating symmetrical 3-D shapes, like bowls and chess pieces. The bowl was really easy but the chess piece was kind of difficult in certain areas. There were no dimensions so I had to base the entire drawing on my own numbers. After some trial and error I finally got a pon that look some what like a pon.

Assignment M was fairly simple, I did the whole drawing by first drawing it in 2-D and then extruding it. The extrusion tool is probably one of the most useful tools when dealing with 3-D objects. Some of the dimensions were not given so I had to get out my calculator and do a little math.

In assignment N, I drew the shape in 2-D and extruded it. I used the hole boring tool to create the holes. That tool is really to use and it gives an elusion that the model was much harder than it actually was. The drawing to the right did give me some trouble; I didn’t know how I was supposed to actually go about drawing it. I just messed around with tools until I got it right.

In assignment O, I did the basic extruding but I was introduced to a new tool, the turning a face on and angle tool. This tool was very hard to use and it was more like guess and check when deciding what points to click, however the tool does help. This tool is great at making or fixing the angle of a face. It took me a while to figure out how to use the tool; I had to get help from the teacher.

Assignment P was very interesting; the shapes were actually fun to make. I used a tool that created and angle by clicking 3 different points. The tool can make very oddly placed angles on objects, the first drawing looks like a plow and I have no idea what the second one is, it looks like a part to a piece of machinery. I had no idea how I was going to make the objects, but in fact it was actually really easy, I did have some trouble dimensioning my work.

Assignment Q is my last drawing. I used the same tools as in Assignment O, I did use a tool to take out the oval shape in the middle of the object, but it was not anything special. The tool I used is really handy in punching out parts of an object, it kind of like the hole drilling tool. The two slanted faces on the top were kind of difficult to make. I had to make a angled line coming off the top and use it as a guide.
