Excellent post Mr. Mather!

I'm from the very old school and have a tough time learning new "tricks." All my work in AutoCAD has been simple plan and elevation views; pipe, valves, pumps, chemical storage tanks. An add-on for AutoCAD draws all the pipe, fittings, valves, a great add-on!
All are ANSI and the program will generate a BOM for me if needed.

I believe John wanted a 10 x 14 base, a 6" x 6" top, elevation of 6".
Perhaps you could post John's configuration if you are so inclined.

If we had the technology 40+ years ago, life in the sheetmetal business certainly would have been easier.

When you mean "pattern" are you meaning you need to create a flat pattern that will be fed to a plasma or cutter? Or do you just need to represent a transition dimensionally so that a fab shop can produce the transition for you?

I would hate to have to work off only those written instructions without any drawings or sketches. Didn't I see a reference to some figures (I didn't find any) or did I miss something?

I'm guessing John received dimensions verbally from his instructor.
Naturally a sketch would've been welcome.

On another note, my Grandfather was the plant manager for Stroehman Bakery in Williamsport for many years.

Hi,
I've started to work on Plate 3 of the HVAC project. I have no idea what to do next. I am unable to figure it out. Can someone please help and talk me through the next steps

[JD Mather]

What textbook are you using to learn Developments?

I would start by drawing line A-B.
Then at B draw a circle R B-10' and at A draw a circle R A-10'
Where they intersect is point 10. Label this and draw true length lines A-10 and B10.

Attach the file here for next step.

Hi,

I think I have done what you described. I drew line A-B and at each point A and B I drew a 10" radius circle with A and B as the center. Then drew line A-10 and B-10. However this line is shorter than what is on the front view. So now I am really confused. I have attached the file as you asked. As I mentioned before the only textbooks I was using is what was provided by Penn Foster. I have also attached the booklet that describes what I need to accomplish.

[JD Mather]

Where did you get 10" radius?

You have a point #10.
You solved for true length of line from point A to point #10' (that is 10 prime - new designation for position of point. Not 10 feet. Not 10 inches)

That pdf is probably copyrighted. I suggest you remove it. It is one thing to post a relavent image from the pdf and quite another to attach the entire file.

The pdf refers to, "
Follow the instructions in the text to find the true lengths of

all the lines. Label the true lengths of the lines as you create

them."

But any text I have seen shows the true length projection labele like A-10' (10 prime)


The R A-10' and B-10' is actually 18.38477631 inches.
