Final Paper

METC 107 – Mechanical Design and Document

In United States Community Colleges are the most common type of two-year degree

program colleges. The aim of these colleges is to help the students nationwide to a better way to

accomplish their goals. It can be either to achieve a good career faster or to get into a four-year

school by transferring their two years’ worth of credit in a much affordable manner.

Ivy Tech was founded in 1963 as Indiana Vocational Technical College. Before Ivy Tech

was “Ivy Tech”, the school mainly focused on technical and vocational education. However, in

the span of 50 years, the school has gone through multiple changes and today, Ivy Tech is

Indiana’s only full-fledged community college having more than 40 locations. The number of

programs that is offered is more than 150. Also offering more than 100 transfer programs

nationwide. Programs such as, School of Business, Logistics, and Supply Chain, School of

Public Affairs and Social Services, School of Information Technology, School of Arts, Sciences

and Education, School of Nursing, School of Advanced Manufacturing, Engineering and Applied

Science.

The classes are smaller in size compared to a regular four-year school, usually being 22

students in a class, means that the students get more attention to their questions and problems.

Being offered hands-on experiences to the technical course and training facilities, it is a great

opportunity for the students to learn something useful and in a quicker fashion. Professor and

instructors are also extremely helpful, in the sense that they are more focused on student’s

success. If an individual is struggling with a course, they are often immediately helped and get

their problems solved. So, in a way the instructors or professors are actually mentors and they

will guide us with maximum amount of support to our success.

I have been in Ivy Tech Community College since Fall 2015 and I am expecting to

graduate in Spring 2019. Though there are plenty of programs to choose from, I wanted to study

Engineering Technology. Engineering Technology is mostly based on general engineering

including both electrical and mechanical engineering courses. This program focuses on the job

market rather than transferring to a four-year degree. However, if a student wants to transfer to a

four-year school to get his or her bachelor’s degree, he or she can enroll for a degree in either

Electrical Engineering Technology or Mechanical Engineering Technology by transferring the

credits.

I myself do not plan on starting a job right after I graduate with my degree because, my

heart is set on Purdue University and I want get a bachelor’s degree in Mechanical Engineering

Technology and apply for Grad School later. Although, I am not applying for jobs right now, I

have learned a hand-full of technical materials with which I can secure a part-time job in the

industry. The courses I took which can define my skills are EECT 101 Intro Electronics and

Projects, EECT 111 Intro to Circuit Analysis, EECT 112 Digital Fundamentals, METC 107

Mechanical Design and Document, and lastly, METC 143 Materials and Processes. These

courses have a lot to offer and a lot of hands-on experiments to do which can eventually help any

student to get a job the engineering industry.

The course I most enjoyed in my time at Ivy Tech Community College was METC 107

Mechanical Design and Document. The class was a three-credit hour class with contact hours of

two hours in lecture and two hours in lab taught by James Reitz, and supervised by Ivy Tech

Engineering Chair, Andrew Bell. The required text book was Principles of AutoCAD 2017,

Author: Shih, Publisher: Schroff Development Corporation, ISBN: 9781630570408.

The course introduced the fundamental skills necessary for me to take a design from

concept to implementation through virtual modeling and the creation of working mechanical

drawings. With the tools provided the student would learn visualization, established technical

drawing techniques, CADD-based design, and characteristic standards to make mechanical

designs and drawing that can be successfully presented to a production organization to create

accurate parts and assemblies.

Major learning objectives of this course were, how to demonstrate a foundational

knowledge of selected technical drawing skills including sketching practices, how to establish

fundamental ability in computer aided design and drafting systems (CADD), utilizing 2D CADD

to create models necessary for production or manufacturing, and applying standards common to

mechanical design to create documentation necessary for production or manufacturing. While

going through the objectives of the course, I learned how to use the 2D CAD model creation

tools, visualization and projection theories, how to do Multiview and isometric projections, how

to dimension and annotate my designs, learned about sections, breaks, and auxiliary views,

which eventually got me familiarized with 2D CAD user interface.

The course had multiple homework assignments which we got to start in class after

lecture. Lengthy assignments took roughly six hours to complete and the shorter ones were

completed during class time. The homework assignments were 10% of the final grade or 100

Rahman 4

points total. Throughout that semester we only had two tests with each carrying 15% of the final

grade or 150 points each. Although the tests and homework were part of the grading the biggest

chunk of points were distributed to the three essential projects with 20% of the final grade each.

The projects were Mechanical Engineering Project, Architectural Project, and Civil Engineering

Project.

For the Mechanical Engineering Project, we were each given some topic to choose from.

The topics were, Solar Water Heater, Solar Space Heating System, Wind Turbines, Water

Collection System, and Trombe Wall. The purpose of this project was to research and design a

sustainable or green technology using AutoCAD, and illustrating the technology as a

modification to an existing residence. Although all the topics were very interesting, I was

intrigued to choose Trombe Wall. After submitting the project to the instructor, I had to give a 5-

10-minute presentation.

A Trombe Wall is a system for indirect solar heat gain. The wall consists of a dark

colored wall of high thermal mass facing the sun, with glazing spaced in front to leave a small air

space. The glazing traps solar radiation like a small greenhouse. The average cost of this system

is roughly around $120 per square foot. Like any other device or system, a Trombe Wall has its

advantages and disadvantages as well. Advantages such as, it provides a comfortable heat, does

not need any maintenance, easy to build, materials are inexpensive, for example, masonry and

concrete, and it can reduce heating bills by large amount in the winter. With its perks there is a

drawback of the exterior walls becoming the means of heat loss during extended overcast days.

However, this is not a problem for an interior Trombe Wall.

Here are some pictures of my drawings and layers I used to come up with my design;

Here is my drawing fully dimensioned the layer properties turned off;

The commands I used to create my design were, line, circle, rotate, trim, and hatching.

For example, the house wall, house roof, and the Trombe wall itself. It took me only three days

to come up with the design and complete my project and also another one day to prepare the

PowerPoint for my presentation.

Next was our Architectural Project. The purpose of this project was to design a floor plan

of a residential structure. The design possibilities of this project were endless. We were

suggested that it would be easier if we created a floor plan of the house we already live in or a

floor plan of house or apartment we wish to live in/build in the near future. I chose to create the

design of the apartment I was living in back in Fall 2018. The house was a one-bedroom

apartment and at the same time, it was my first apartment I moved in to when I came to Fort

Wayne from Bangladesh. The rent was around $409 per month including electricity, internet, and

utilities. There are many perks of living in a small apartment. For example, it was easy to clean,

electricity bills were low as it did not take much time to cool or heat, and the biggest thing to

which I was sold immediately when I saw the apartment was the big living room. However, with

those perks, I sometimes had problem with the small kitchen.

Here are some pictures of my design;

The commands used were Multiline, Architectural Dimensioning, Trim, MLEdit,

MLSyle, Scaling, and CAD Blocks. After completing my design, I had to put it in a floor plan

template using AutoCAD as well for the sole purpose of having a blueprint. If a company want,

they can build the exact apartment I used to live in because I have provided every information

needed.

Here is the floor plan template;

The calculated area of the house was 466.09 square foot. Although it seems that it was a

complicated project, I happened to finish it within two days, and another one day to prepare for

the presentation.

Last but not the least, the Civil Engineering Project. The purpose of this project was to

draw a site layout plan for a parcel of land on the Ivy Tech Campus. The parcel was given to us

by our instructor James Reitz, and on that lot, we had to come up with the layout of the building,

and a parking lot. With the parking lot we were given the task to maximize the number of

parking spaces with 2% of the parking spaces reserved for handicap parking that can fit onto the

site.

The dimension for the building were provided by the instructor. So, here is the given

dimension and my design complementing it;

The counted parking spaces were roughly around 1674 with 42 handicap parking spaces.

Therefore, that comes down to just a little 2% handicap spaces. As usual like every other design

my design had its pros and cons as well. Pros such as, lot of parking spaces including handicap,

enough space for traffic flow, two entrance to the lot. Cons such as, some parking spaces has

only one-way traffic flow, and there is a lot of unused space.

Rahman 15

The tools that I used to create the design were, line, arc, circle, mline, mlstyle, mledit,

move, copy, rotate, and trim. Amongst the three projects that I did, I found this one the most

challenging. Designing the layout onto the given lot needed a lot of concentration and precision.

Nonetheless, I could complete it within two days, and one following day to prepare for the

presentation.

This was a very good introductory class to learning AutoCAD. Everything a student

needs to know about 2D drawing starting form the basics to the in-depth of the matter, can be

achieved through taking this course. The homework will help a lot in getting used to the program

as they follow the flow of the lecture. I would say that I have learned a lot from this class. Even

if I ever had issues with any of the commands, I could refer back to the lectures and get my

assignments done. Hence, I would recommend others to take this class if they are hoping to learn

how to use AutoCAD. Any sort of AutoCAD project can be done after completing METC 107

Mechanical Design and Documents.

Ivy tech serves the people of Indiana through accessible and affordable world class

education and adaptive learning. The school inspires students to achieve their goal both in career

and in education. Ivy tech embraces their vision of economic transformation inspired by the

education and earnings attainment of the people of Indiana, the vitality of their workforce, and

the prosperity of their unique and diverse communities.
