PAT Key-Hole Question

Well, I was working on Key-hole portion of the PAT and ran into a few questions with answers that involved certain flipping or mirroring of the object.

So for key-hole, are we allowed to flip the shape? Is there a difference between the view from the top of the object and the view looking from the bottom? from the right or left? What angle did you guys viewing the most helpful?

Thanks for the help! = )

Actually w/ keyhole, there really isn't too many strategies to apply.

You have to consider 3 views in total (front/back, top/bottom, sides). Both the f/b, t/b, and sides veiws, respectively, should be the same.

Gosh...it's really hard to answer this w/out an example....

Bascially, you can rotate the object to make it fit the keyholes, but once you start placing the object through the keyhole, you can not rotate again.

How you go about this depends on your answers choices. The key to this is that if have decided that you are going to use (for example) the bottom view to pass the object, then you have to make sure that your eye & brain are working together to solve these problems....what I mean is that very often you'll start w/ the bottom view, then a piece of the answer will make your eye want to look at say the side veiw or something...you can't change btw views, either the key hole fits the entire bottom view or it doesn't.

I hope some of what I have wrote makes some sense. I'm sure it's useless...but I'll post it anyways.

Thanks for the input!

I'm just confused to why it would be only 3 views (front/back, sides, top/bottom) rather than 6 (a top, a bottom, right end, left end, front and back)?

Wouldn't looking at an object from the front and the back yield two different shapes? For example, say we have a 3-D shape of the letter "d". Would it be possible for the answer be a key-hole of the letter "b"?? Since standing and looking at the object "d" from the behind would we see a "b"?

Any help or advice will be wonderful!!

Yes, you are right, it is technically "6 views." However, looking at the object from the front and the back would not yield two different answers, since you are looking at the silhouette or outline that a combination of the front and back views would yield (if that makes any sense). This is untrue for the TFE questions, where the back view would most likely yield a different result than the front view. So, for aperatures, you would take the front view you are seeing and overlap it with the back view and the outline of the two would yield the front/back aperature. This is how you arrive at three views for the aperature questions (top/bottom, side/side, front/back), but six distinct views for TFE (Top, bottom, right end, left end, front, back -- DAT, obviously, only focuses on Top, front and End).

Hope this helps!

Oh, also, I totally missed your question on the 3D shape of the letter d. I don't get how looking from behind the object you see the letter b? I don't think it is possible for the answer to be a key-hole of the letter b, but it could be the letter p if you do a 180 degree counterclockwise rotation and then insert through the front/back aperature. I think the side/side aperature would be a rectangle, and the top/bottom aperature would also be a rectangle smaller than the side/side aperature. If this still doesn't make sense, perhaps try building a 3D model of the letter d using clay or something so you can visualize this better.

Umm another thing, the front/back aperature for the letter q could be the letter b if you rotate 180 degrees prior to insertion. But, the front/back aperature for the letter d will never be b, regardless of orientation or degree of rotation. The side/side and top/bottom aperatures for q and d will be the same, though.

Someone please do correct me if I am wrong!

Hey!

I guess I'm a little confused because sometimes, for example, there can be 2 possible SIDE views (looking from the left to right, or right to left) Although the outline is the same (in size and shape), it could create 2 different answers, which are like mirror images of each other?

I was just wondering if it's possible for either of the 2 to show up as an answer choice since in the practice problems. I usually encounter the (top to bottom view) (right side to left side) and (front to back)...instead of (bottom to top) (left side to right side) or (back to front).

somebody help!

thanks =)
