One of the classes I take at school is AutoCad, which is computer aided design. Kind of like drafting. A few days ago I got ahead of my drawings and had some time to waste, and this is what I came up with...

Two friendly comments, Chris: 1- it is "Bored" not "Board" (more studying English?) 2- you've designed everything to 1/10,000th (of an inch?) ; those are some pretty tight tolerances! Is it 12 inches or 12 feet or 12 millimeters long? By the way, I used to design model airplanes on CADD (not AutoCADD) as a hobby - it can be a lot of fun.

Chris,
You need to go into your dimension settings to show your dim. in feet and in mm in parentheses below feet.
Mike

P.S. what release are you using?

I took "Drafting" (AutoCad) in my Freshman year of high school, the next year the class was canceled due to lack of interest. We did things like the layout of your Turtle, floor plans for houses we designed (including electrical wiring, furniture, appliances, etc), and complex 3D objects with various angles, arcs, etc. It was definitely my favorite class in all of high school.

Keep in mind guys that this was created in less than 15 minutes... I think it's dimentioned in INCHES. I enjoy the class, but this drawing is really basic.

Welcome to AutoCAD Chris! I've been using it where I work since 1999 and am now using AutoCAD 2009 for two-dimensional drawing and Inventor 10 for three-dimensional solid modeling of assembly/fabrication equipment for the door & window industry. I recommend that you dimension circles with a diameter callout and use a different line color for object lines than what you use for dimension lines. I use the standard blue for object lines and black for dim lines. :)
With a little more experience, maybe you can help Ed design more reproduction parts for Studebakers? :)

By the way, good job!

Same here, I had what was then Drafting as a freshmen in high school. Prior to the new school being constructed across the street with a much more improved shop, we drew up our stuff through the traditional methods, and the CAD computers the higher level students used, were the older 286 and 386 green screen PC's. We used the large drafting desks, the drafting pencils, the drafting paper, the T-square, rulers, you name it. I wasn't particularly good at it, mostly because it was the first drafting class I ever had, and I was a shy sloppy. But, I went out purchased the drafting pencils, the wonderful oversize white oopsy(as I like to call them) rubber erasers, and the rulers to improve my skill. By the end of the class I had improved quite a bit with my parent's and my teacher's help. The final drawings we had, which were drawings for a small Shaker style cabinet, were going to be used in the following Wood Shop course under the same teacher. When the school moved across the street, everything was upgraded, so as far as I know the initial methods are still used, but almost everything is done on CAD. The class is plenty popular, not only because it the first shop class that is needed for the other shop classes, but also many of the kids that continue on in any serious manner in drafting or CAD usually end up in one of the Manufacturing classes with the teacher.

I still have the cabinet too, it's used to house my computer games and my PC speaker :cool:. I should also mention that it is "bored", rather than "board". At first, I thought the board you were referring to was the mainboard or motherboard in the PC :p.

When I had drafting, circa 1962, all we had was a pencil, straight edge and a protractor.

When I took Mechanical Drawing, or Drafting, I didn't get real good grades for my Excellent work. I always figured it was just another case of a teacher out to get me. I mean after all, with a name like Chauncey Gorsage, what do you expect?
Anyway, when I retreived my course book from my mother's house a few years ago and looked through it, I was truly surprised. Surprised at the poor quality of the work I was looking at!

Well I could see where the teacher was coming from, especially now. I had a bad habit where I drew and redrew lines and sometimes I wouldn't get my old marks completely erased. When it came time to turn it in, the teacher was not only retired from Caterpillar here, which meant the bar was set a little higher, he also had to be able to read the drawing to correctly produce the dimensioned parts. I don't think it helped any when he got the drawings back and they still had lines on the drawing where lines shouldn't exist :p. Ironically enough, I still had those problems of the pencil marks when I did my calculations in physics a few years later :p.

I started on AutoCAD 1.6 after many years of T Square and Triangle. The whole install program and sample drawings fit on 1 3.5" floppy. A little over 1 MB. It did everything that the new versions did in terms of regular drafting work. Of course, I moved to 2.5 D and 3D over the years. Most of my design is done in SolidWorks at this point. But it was a major pain to make the change from a history based modelling program to feature based. There are still times when I could cheat and go back to AutoCAD and do something much faster, but I resist the temptation. Learn your 3 view layout and detailing. It will serve you well even if you don't draw for a living.

AutoCad ???? When I took drafting in HS we had to do our final drawing with drafting pens and bottled ink. I also had to take a mechanical drafting course for one semester as a Freshman at the University of Alabama's College of Engineering....

My AutoCad equipment was german manufactured by Staedtler and looked something like this ...

What's a pencil? :D

I know that this may be wholly unnecessary, but the items in this photo do carry some relevance to this discussion here :p.

From the left, that is my old Staedtler large eraser. That thing did a heck of a job on the largest of mistakes on drafting paper. If that didn't work I also had a rubber artist eraser as well. At the top was the leads(with the holding cartridge underneath) that if I recall went into a clamp on the mechanical triangle on the drafting board. Basically it was a pencil without the external casing on it. When I started having troubles in drafting, on the advice of my relatives(whom was a shop teacher himself), we went out and spent a small fortune on those Staedtler pencils, Staedtler erasers, a T-square, and some basic geometry instruments. I will say that for the basic stuff, it's good, but it's not cheap. Underneath those are my #2 pencils that are made out of recycled blue jeans(the blue one) and recycled money(the green ones). I have probably had those since about 1993 or so. Underneath those are what I call my lucky black magic, Mirado Black Warrior pencils that I take into every paper and pencil test with me. Ironically enough when I went in for my chemistry test a couple weekends ago, I could not find those anywhere so I went with those blue and green pencils, only to find my black ones in my desk tonight. It's nothing major, just a smooth black #2 pencil with a nasty sounding name. Finally, the one on the bottom is an ordinary #2 Roseart pencil that everybody thinks of when they pick up a pencil :rolleyes:.

That may be the silliest answer I gave, but in the far future, people will now know what a pencil is :p....

Oh right, what does a pencil do? It's a writing utensil that is used to scribe lines onto paper, or any writing medium, and provides pictures, illustrations, or basic communication between one or more people. The pointed end makes the black lines, the pink end removes them :p :cool:.

Well for us Machinist who have to make the part, there is no tolorance diminsions. Like axle fit, Do you want it to just roll +0.060/ -0.060 or do you want it to last for ever + .002/-.0001.

Funny that you all should mention 'pencil.' Until I retired in July everyone ridiculed me for still using a #2 pencil for note taking at meetings and red pencil for grading my students' work!

I recall having some sort of drafting class in HS, but I think it was part of a shop class in perhaps 10th grade. Mr Ruud would have been the teacher. That is 30yrs ago. I do recall the T squares. When I was taking electronics at the local trade school after HS in the winter of '85, we had a quarter of drafting. Mostly that was geared to schematics and circuit board layout as you would expect. All ink on mylar and using tape for the board layouts. I think we got to "observe" a demo of CAD system one class period. The trade school also had majors in drafting so those students got more general (and deeper) training in it and actually got to use those CAD stations. When I was in engineering college later in about '88 I had another quarter of drafting. This was more general and mechanical. But! Still used T squares and so on. We had 1 lab period using a CAD station. I still shudder from that exercise where we needed to rotate a isometric view of a item through several angles by hand with rulers and protractors (I think). ugh. About that same time at my intern job they were using AutoCAD (probably version 8 or 9) running on '286 PC's with 20MB (!!!) hard drives and color! monitors. I got a lot of on the job training on those copying/redrawing part prints from paper into the computer and also doing simple drawings of prototypes. I worked that same place for a while after graduation through the end of '94 and in the end was using AutoCAD version 12 I think. I was designing mechanical parts and doing electrical schematics and PC board layouts by then.

I've not really done much of that sort of work since. I still do electronic schematics and some other types of simple drawings occasionally at work but the software used is just for schematics or is some low end generic drawing software. The board layouts and mechanical stuff at work is done by specialists. They use Pro-E for the mechanical stuff and Mentor graphics for the board layouts. Big $$$ software.

I think my experiences have served me well though since I am pretty good (if I may say so) at making 3D sketches of design concepts and illustrations, etc. Seems like a lot of the younger engineers I run into have poor ability in that area. Maybe they don't have drafting classes as much anymore even in engineering college....

Starting 8 years ago, I took AutoCAD at night school to get out of a dead-end job. In 2006, I did land a job involved in design of air compressor stations and pump skids, although things did slow down, and I was asked to move north of where I am now. I accepted a buyout as I have no desire to move north; only south or west where the winters are milder. I'm currently back in the HVAC industry, but at the same wage level as I was getting in the oil-related work. One reason for being able to negotiate a comparative wage structure is because of my capabilities to work with AutoCAD. As well, I also have the 2-D program on my home computer as I do get asked to convert hand sketches into presentable drawings/diagrams. It is a valuable skill to possess to today, even on the Forum as I used it for my contribution to this thread: http://forum.studebakerdriversclub.com/showthread.php?17909-Design-a-Post-66-Studebaker-Grille&highlight=hidden

[UPDATE] Rehired by the same company where I started in 2006 on April 30th of this year. Activity did pick up again in the oil & gas industry.

I suppose the CAD people would not need this. (A left over from 1960's drafting.)

I use Kubotek KeyCreator Version 7.5 with the KeyMachinist cam plugin. It used to be called Cadkey and I have been using it since Dos version 7. No schooling, just taught myself and starting drawing 2D/3D cad files from the beginning. This Cad program is allot more user friendly then Autocad.

Here is a snapshot of a 3D cad drawing I did for one of my customers. There are so many lines in the bear head so I included a picture of the finished brass master I CNC machined from this file. I had to make this master so my customer could cast pewter medallions from it.

Here's my "spare time" 9th grade drafting class project using pencil and paper (old school). It's dated March 17-21st 1980, so I would have been 14 at the time. As a complete surprise to me, on my 15th birthday (about a week later) the keys to that car were in a card from my Uncle!

I know the proportions and lines aren't correct, but the car had been in a barn 20 miles away for a few years and I didn't even have a picture to go by, just my memory. This was before the digital age and no internet to just look one up, but it hangs proudly in my office anyway.:cool:

I got the intro to drafting in junior high with pencil, paper and T-square, had 4 years of it in high school, another year in college. As a high school senior, we had to make a series of drawings of the parts of a globe valve - in ink, on starched linen. CAD on a computer is much faster, better, easier. Currently, I am using DesignCAD at home for both 2D and 3D drawing. See www.imsidesign.com (http://www.imsidesign.com) if you want have CAD at home for under $150. DesignCAD is pretty good at 2D and 3D, though not perfect, but at $99 it's a good buy. For straight 2D work, their TurboCAD Deluxe is more capable. The higher cost versions do good 3D. At work, they use AutoCAD for 2D (wiring and piping diagrams) and SolidWorks for real 3D modeling. We've even used SolidWorks to make animations of complex moving machinery.

Just this morning, I took a 2D file to the local sheet metal shop to have them laser cut some 3/16" thick steel parts for me using a .DXF file from TurboCAD. Here's the Indy car frame and wheels modeled in DesignCAD:

I also used a 3D file to get the casting pattern made for the Indy car aluminum intakes. It's fun to see a drawing get transformed into real metal!
