Design And Drawing For Production

In Design and Draw for Production we have been working on our technical drawing unit. One of the drawing types we have worked on were Section views. Section view drawings show the interior detail of the object. There are six section views, full section, half section, offset section, aligned section, revolved section, and Aligned section.
The section view is cut with a cutting plane line. A cutting plane line shows where the cutting is happening, and where you are looking at the object.
A full section and half section use the cutting plane straight across the object. In the full section the cutting plane line cuts fully across the object, and removes half. In the Half section the cutting plane line cuts halfway across the object, and removes a quarter.
An Offset and Aligned section both bend the cutting plane line. The difference is that the Offset section cuts the cutting plane at 90 degree bends and the Aligned Section bends them at specific angles.
A Revolved and Broken out section both use short break lines instead of cutting plane lines, and keep the drawing in one view. A revolved section cuts a piece of the object and revolves it 90 degrees to see the interior detail. A broken out section uses short break lines and cuts the corner of the object to show a small piece of the interior.
The Section view drawings were the hardest for me because there were new line types, and so many different section views. It was also one of my favorite drawing types because it challenged me, and it became fun as you practices more!

In Design and Drawing for Production, a lot of techniques have been uncovered for the students that take this class. Lately in class we have been working through Isometric drawing and learning how to put together a 3D piece of work. We learned to use a triangle that has an angle of 30 degrees for the horizontal lines instead of a T Square. Isometric drawings are probably the most favored in the Technical Drawing Unit because they are the easiest to create. They only use Object lines. Projection lines can still be used but they really are not needed.
Technical Drawings are hard to learn how to do. Learning all of the different types of lines and the measurements on triangles is sometimes difficult. The only measurements that seemed to stick in my head were for the Title and Border block. Learning all of the tools and how to use them is not hard. The T-Square helps to draw straight horizontal lines. The Ruler obviously measures. Both triangles, 45 degree, and the 30-60 degree both measure a 90 degree angle. The Eraser shield is used to erase projection lines without erasing lines that you have to pen in. The Compass is used to draw circles. And a protractor is for angles. All of the tools are explanatory and easy to remember. When someone finishes a drawing in pencil they can easily get angry if they start in pen, and haven't fully erased a Projection line and they go over it with pen.

So far this year, in Drawing and Design for Production, we have been focusing on drawing Multi-view drawings. Multi-view drawing are drawings of an object that have two to six views from different spots. A specific type of multi-view drawing we are focusing is an Orthographic Drawing.
An orthographic drawing has three views, the front, top, and side view of the object. Every class Ms. Roman gives us two drawings to complete, but we don't just sketch it out on lined paper. We have to use drawing tools so our drawings are accurate and perfect.
An example of an Orthographic Drawing:
After she gives us the drawing we go and get our drawing tools. To finish an orthographic drawing it takes a lot of tools. We need to get our drawing board, t-square, ruler, straight edge, eraser guard, paper, pencil and pen. I won't give you a lesson on what these tools are and how to use them because they are what they sound, For example, a straight edge is literally a straight edge of a drawing triangle used to draw vertical, straight lines.
After we get our tools and square on paper on the drawing board we have to draw a title block before we draw the object. A title block surrounds the border of the paper. It is where all the information goes about the drawing. Information such as, name, title, date, scale, and class block.
An example of a Title Block:
After we draw the title block we draw the three views in pencil. We always have to use are straight edge and t-square when we draw. Our orthographic drawings are graded on how precise our drawing is compared to the object.
We have to use projection lines to project the measurements to all three views. We erase them after but it takes less work than measuring out everything, and the measurements in every view will be equal.
After the drawing in pencil is perfect we go over it in pen. Personally this is my favorite part of the drawing because it make my work permanent. After we finish we erase the drawing so there will be no pencil left, and only pen. The Orthographic drawings only take about thirty minutes. We can complete two in each class period along with some notes about new concepts of technical drawings.

Technology and Design and Drawing for Production class can both be seen as tools, and just the same for all tools, if they are used correctly, they can serve to be extremely helpful and assist us when we face obstacles. I really like Design and Drawing for Production because it has helped me to grow academically, become more useful in the field of technology and form better relationships with teachers and students. All the while, we are having a lot of fun as well! The activities we take part in and the lessons we are taught encourage learning, feedback, analysis, trials, team work (and therefore communications among students) and emphasize time on task. In this class we are exposed to real life systems, issues and situations to solve. My favorite one so far was just recently finished in class. The assignment required us to work in teams, chosen by Ms. Roman, to complete a simple task in a complicated way. Inspired by the Rube Goldberg machines, which are basically just big chain reactions, our simple task was to dispense the proper amount of hand soap into Ms. Roman's hand. My team was called the Teenage Mutant Girls because our team had all the girls in the class including, Logan Ferreira, Crystal, Samantha Parsons, and myself. With three days to design and build our machine that and to have 5 interactions with a limited amount of supplies, we finally came up with our idea. First we cut out a piece of wood as our ramp and sanded it down in the middle to create a land for our marble that would keep it in a straight line. Next to that we connected a bowl and a cup as a platform for our Tetherball like component composed of a hot glue gun stick, with a rope attached to it and the wheel hat would hit the marble sending down the ramp. After it was released and the ball rolled, it hit and sand paper tube filled with glue, which hit a popsicle stick placed in a binder clip like a See-Saw. When the tube hit one end of the stick it pushed up the other end, which hit the spoon that help the hand sanitizer in it and sent it into the hand. This project was one of the most fun projects I've ever been a part of and although it was hard work because we had limited supplies and had to complete many trials, I was very pleased with our end product.

I can't tell you how many times I've been in the middle of trying to explain something to someone, when I finally stopped and said, "Here, let me draw you a picture." If I can't quite describe the shape or pattern, I draw a picture. If I have an idea for a new invention, I draw a picture. If I get bored, I draw a picture. It can be so helpful! My ideas of drawings have drastically changed since taking Design and Drawing for Production (DDP) though. Now when I decide to draw someone something, I find my self using DDP terms, lines from the drawings that we learned in class, drawing them in different views etc. I learned all of these things at the beginning of the year when we were still studying the basics. Practicing our technical drawings on paper is what we did for about the first half of the year, but then we got to move to the computers and make our ideas a reality. That's really fun, but I think drawing on paper is essential and probably my favorite part. I had no idea how complex drawing could be. There are so many different types of lines, views, tools and symbols. All together I think we learned about 50 in total, and about how they work and why we use them. And don't even get me started on the measurements!! You'd think that the height and spacing of any text on the paper, or the width of the arrow point on a dimension or extension line wouldn't matter, but you'd be wrong. Even though this might not sound as fun as I think it is, I enjoy a challenge and the finished product brings you a lot of relief and pride. I think that another reason technical drawing is enjoyable is because even if you aren't an artist, your drawings can still look great! Personally, I am a fan of the stick figures. They seem to be the only things I can actually do when drawing freehand, but these drawings come out so cool looking! If you want to see some you should come by the lab and check it out.

You wouldn't think that you could build a checkers board on a computer but in Ms. Roman's technology room that's one of many things you can do using the computer. Ms. Roman's class is full of amazing surprises such as building a checker board. Now we can do this deed many different ways but the main tool we use is called Autodesk Inventor. It is a computer based 3D solid modeling resource. When you do build your checkers board its easy all you have to do is draw out a square then make it 3D and you use a tool called constrain to connect them. After that is done you can even customize your own board pieces to go with the game. I know what you're thinking how will you know how where to put the pieces well that's easy all you have to do is color each piece to whatever you want it could be red, blue, green, you name it. Now if this doesn't interest you there are loads of other things to do here. You can actually build stuff like chairs, bridges, and even do other cool stuff on the computer like build a train but if you don't believe me then come check it out for yourself.

That is exactly what we have been doing in Design and Drawing for Production. In this unit we learned how to use a computer 3D solid modeling program, Autodesk Inventor, to design parts and assemble them in order to create final project. One of the most interesting projects that we did was creating and animating a train which could move up and down a track on its own. To begin we created many pieces of the train, such as the body, the track and the wheels. Then after we finished each part the entire train was assembled and constrained to the track using assembly constraints. In the program, colors of each piece could be chosen adding an extra artistic component to the project. Finally we allowed the wheels to rotate using a motion constraint and the train was animated with the ability to drive up and down the track. When the train first made it up and down the track it was both exciting and satisfying to see the work that we put in come to fruition in a working train. Before this year I would have never believed that I would be able to create a working train on a computer or anywhere else. The tools that the class learned during this project and throughout the whole year will be a great help moving forward into other classes, technology based or any other.
