    I am trying to draft the 10x1406 hvac pattern and 10" diameter transition piece.
    Can you please post an image of them.

    Thank you.

    Post of image of what you have so far. Is this a Penn-Foster project?

    Are these the ones that you are trying to do? Remember that your project may be different.

    Hello: I am a little confused with the HVAC 10x14x6 pattern developments:
    We are to do 2 pattern developments in which the front views show the transition's larger side (14" wide) and 2 pattern developments in which the front views show the transition's narrow side (10" wide). My first 2 pattern developments look similar to CAR5858's post #3 top two. But, I am stuck about how to start the other two. What do the 2 bottom pattern developments of Car5858 show. Can someone post an image of how the narrow side (10" wide) should look, or am I missing something?
    Thanks!!!

    This is a little complacated, but you can see the development process. First find the true length of line 3-4 (red dashed circle), next find the position line 2-3 (cyan circle). Since lines 2-3, 3-6, 6-1, and 1-2 represent the narrow side, these are at the top of the flat pattern (see screen shot). Use the circles to lay out the flat pattern. By positioning the circle radius at their respective point, the intersections of the circles create the end points of the stated lines.

    Wendymoose, you should be starting a new thread with your question. Use Penn Foster HVAC plate one as the title.

    Plate one is the floor plan with the ductwork. Do you have the floor plan completed?

    Are you stuck on the duct layout?

    The instructions were pretty clear in this section. I did not have a problem with it.
    You will also have to add a table to the right of the drawing. This is explained in the instructions.

    hi again Car5858, I was trying to lay out the rooms from page 10 of the project book. omg, I am terribly sorry. I received a sample plate drawing with my project book and just did not realize that this is what they are wanting me to copy exactly. I was getting confused because I could not find the play-room dimensions along with bathroom #2. Thank you for clearing that up for me. I was trying to go with the instructions straight out of the book instead of just copying what they sent me. Never thought it would be that easy and I appreciate you helping me clear that up. Thank you
