# -Penn Foster? HVAC transition piece

## Recommended Posts

Well thank you ReMARK. So far, that makes the most sense. I don't get how I didn't notice that it appears to center on the points A, B, ect. Freaking awesome. now I have to lie down for awhile, rest assured, I shall tackle this today. And if anyone else has any input, it would be much appreciated.

Alright, I figured it out. Triangulating using the arc distance between the numbered points in the top view and the true length measurements. . . Example; take the arc distance between 10 & 11, draw a circle from point 10 as center with the radius of said arc distance. . . then draw a circle with the radius being the true length of line 11-B and a center of point B. . . now, where the two circles intersect, that is your point 11. I really hope that this helps somebody, as I know that I am not a vocal teacher, I teach the same way that I learn, by doing. . . thus, I am a spatial learner.

Kudos to everyone on this site. . . for without this site, I would probably allow myself to lower my GPA just to be done with PF.

I always used the lisp to do transitions from square to round here with the already posted lisp 2 months ago.

please supply the blank squares with dims so i can run it post the results for you to compare output.

I doubt that Penn-Foster even mentions lisp routines and their use so I would not count on a student knowing what you speak of Rob. You might want to include a brief explanation of what a lisp program is and how it is loaded and run.

ReMARK would be correct. The only time that LISP is mentioned in the course is in the Appendix of the text book Discovering AutoCAD 2013. And it is a very short, only telling that it is a customized routing created using language other than macro. Oh, and that transition piece is not the one discussed in this thread.

How do you move forward after you have found the true lengths? I am having trouble finding the angles between the true length pieces

Did you look at post #40 of this thread? Have you also read through other threads regarding the Penn-Foster HVAC project? Some of them contain images of the plates. I think you are looking for plate #3.

ReMark!

Do you have a full screenshot of this plate! Looks like is very similar what i am working on. Its will really helpful for me. I almost done that. Thank you so much

I would have to check my home CAD system. The image I posted earlier was made from a drawing I had on my work computer. I'm not sure I have the project you are working on.

The duct and registers and similar. I will really appreciate if you can share with me this post.

You'll have to give me a few minutes to fire up my CAD computer and have a look around. I'm on my laptop at the moment.

I think I may have found the drawing. The title block says it is Project 9. Does that sound familiar? What exactly do you need to see? Is it the floor plan with all the ductwork?

I hope this is what you were looking for.

Hi everyone! I'am doing project 9 HVAC 14x16x6, so far i think i am lost in numbers. ( So this is part of instruction if somebody done that. Can you help me guys put numbers on the right spot.

Drafting HVAC patterns can be uncomplicated as long as

you remember that there’s no single correct way to do it.

To demonstrate this point, you’ll be drafting a 14 × 16 × 6

pattern in four different ways on Project Plate 3-2. (Note

that this transition piece is 16″ long.)

Remember that you need to show both a top view and a front

view on your drawing of the ductwork. The top view shows

what you would see if you were to look through the ductwork.

Therefore, since this transition has four sides, you can simply

let each side be the front view and draft a corresponding

top view to set up the four pattern developments.

On the upper half of Plate 3-2, place the two pattern developments

in which the front views show the transition’s larger

side. On the lower half of Plate 3-2, place the two pattern

developments in which the front views show the transition’s

narrow side. Draw all four pattern developments at realworld

measurements.

Follow the instructions listed here when drafting the top view

and front view in the upper-left portion of the plate.

1. You’ll be showing the large side of the transition piece

as the front view. Place the 16″ opening of the transition

piece at the bottom, the 16″ side of the transition

piece at the right, the 14″ opening at the top, and the

slanted side of the transition piece at the left. (Keep in

mind as you’re creating the development that the

slanted side of the transition piece isn’t the same

length as the straight side of the transition piece.)

Drafting with AutoCAD Elective Project 56

2. Label the slanted side of the transition piece TL since

this view shows the true length of that side in the front

view.

3. Label the shape shown in the front view TRUE SHAPE.

4. For the top view in the upper-left portion of the plate,

label the corners of the 14″ opening 1, 2, 3, and 4,

beginning at the lower-right corner and continuing in a

clockwise direction.

5. Also, in the top view, label the corners of the 16″ opening

5, 6, 7, and 8, beginning at the lower-right corner

and continuing in a clockwise direction. The lower-right

corner in this top view, therefore, will be labeled ″1,5″

since that single point in the top view represents a corner

at each of the transition piece’s two openings.

6. Label the corners of the front view based on the points

you numbered in the top view.

Did you check some of the other Penn-Foster HVAC project threads. That drawing looks familiar.

Hi i also had a question about this project. On plate 4 of this they ask for you to draw a transition piece and nothing more. i feel like im missing something. like are they only asking fr the transition piece detail and thats all?

Just to show you what i meen.
