what is the question?
|dw:1450358257854:dw| |dw:1450358318079:dw| Draw the isometric (3d shape for that): I am confused between 2 shapes
yes, that looks like the shape they want
But there is center lines
so I thought it would look like this :|dw:1450358551333:dw|
By fitting the circular part up the shape , If we projected a circle we can circle, rect, rect
But what's the explanation for the center lines ?
What is the question about the center lines? the center line of the front and the center line of the side are different lines.
Can you explain what you are thinking?
Are you saying the top is circular?
The center lines are drawn only to indicate the center of a circle.
if you got the S.V , F.V for this shape, you will end up with the given 2 views.
I don't know the details of engineering drawing, and can only use common sense (which sometimes does not work). Is the question, "The shape they show does not have a circular top, but the center lines mean it should have a circular top"
I am confused which shape to use the font + side view of both of this 2 shapes are the same (as the given) the only difference is that the one with circular top satisfy the center lines given..
It's almost making sense. It would help if you posted the full question (or a screen shot)
Here is the ful|dw:1450360035590:dw||dw:1450360095935:dw|l question :
ok, and the center line in 3D would go straight down the center of the shape ? like this: |dw:1450360341268:dw|
If the center line really means a circular top, it also means a circular bottom ? Are you positive the center line means the top/bottom are circular? How do you show a shape that does not have a circular top/bottom?
Now we have 3 choices.
Don't you need 3 views (front, side and top) to completely describe the shape? How do you do this problem when they give only 2 of the views?
Nah, you can work with the shapes with only 2 views , you can even induce the missing view.
That's good to hear. So the question is , how do we induce the missing view?
The question is draw the isometric (3d view) from the given 2 views, but yeah we can induce it.
we have the same exact problem, induce the third view, with the center lines or without.
The other question I have, is how do you show the top is circular and the bottom is square? Once you put in the center line, how do you know if it applies to the top or bottom or both?
|dw:1450361547822:dw| That's the missing view in all the cases, regardless of the length.
@phi , I can't show for sure until I have like R or d given in length ( 60^R or 20^D) otherwise what I can guarantee is that there is just a circle.
So you use the dimensions on the figure (I don't see how to do that, but I believe you) btw, are the horizontal lines also center lines: |dw:1450361818090:dw|
How would you show the bottom is circular and the top is square?
:( No way unfortunately.
|dw:1450362058075:dw| maybe the answer lies in the word 50 SQ
any idea what 50 SQ means?
I used google it says, It can mean Square ...
yes, I was looking. Square occurred to me. It should be in your notes or book.
so maybe the view looking down on the shape shows a square top ? and circular bottom?
4th shape xD HAHAHAHHA |dw:1450362546829:dw|
So last choice ?
I really don't know, but based on what you are saying, and the cryptic 50 SQ (which must mean something else it would not be there), I would say yes to the last shape you posted. Btw, doesn't that have a different "induced view" than what you posted earlier?
Thanks, I will go with the 4th
@phi, It's correct phi, SQ is square.
Good! I hope you got the correct answer.
