Quick PAT question [PIC inside]

I can't see where in the other two views that the visible line w/ the ? mark can be discounted. Thanks in advance for any advice.

that line should be a dotted line representing a break that you cannot see from the right.


this is VERY simple.

What part of the image proves that the line cannot be solid?

look at it again. theres a block on left and a block on right.

The problem is that the line should be dotted. Its confusing if not drawn correctly.

Yeah, it says it's suppose to be dotted, but where does it show that the line cannot be visible? Is there some assumption I'm missing that if there's no proof that the line there, then there's no possibility of a visible line there? Thanks.

I dunno your question confused me. If the drawing is done correctly, a dotted line should indicate a solid line that is not visible. That's about it.

I ran into quite many questions similar to this one. The actual object is composed of pieces. Think of the two little pieces as two separate blocks that are glued to the rest. That's why the line is solid. You may not see it this way, but I'm sure that it is the least incorrect choice (compared to other choices).

Yeap. That's the only possibility having three pieces of objects glued together ... which may be verified from the two inner solid lines drawn for the lengths of the cubes (at the Top View).

I don't know where this question comes from, but I can tell that this is a bad question set ... 1) Proportions of the three views given do not correlate well. 2) DAT questions will usually be based on one single piece of object instead of multiple pieces of blocks.

Hi,
Check this picture ...i hope it will help.

good luck 👍

Thanks for the diagram isd, and thanks to the others for the help.

I understood the correct choice, but I was simply confused as to why it couldn't also be solid. I thought of them as two separate boxes...that's why I thought it would/could show up as a visible line also. Thanks again.

Hi puncho,
Check this diagram and compare it with the first one.

Look at the side elevation, notice that the piece which sticks out at the front is not co-planer (at the same plane) to the rest of the object...it is set back. Because it is at different plane we will see a solid line.

Where as, in the first problem both are on the same plane.

hope i didn't confused you. 🙂
