Does anyone have any suggestions on the Top/Side/End View problems on the PAT? I am having the hardest time with these and figuring out their 3D figures with the dotted lines and solid, etc. Thanks!

Ditto - one of my biggest issues for the PAT. Any suggestions would be appreciated. My problem is that I can at least eliminate some, but then I'm left with 2 choices and it seems that I always pick the wrong one. My biggest issue is to know whether the lines are dashed or straight. I do realize that the dashed lines are "invisible" but I still have issues with this. Thanks for any suggestions!
 
There is a strategy called event counting. By relating the bottom edge of the top view with the top edge of the front view, and the top edge of the end view with the right edge of the top view and counting their "events", you can eliminate most of the wrong answers. Here is an example:

So looking at the top edge of the end view, I count all of the "visible events" represented by a red circle and the "invisible events" represented by a red square. I know that this edge corresponds to the right edge of the top view:

Now, by comparing that information with the answer choices, say B, I can eliminate some of them. The blue markings show an incosistency with the relationship that we made in the previous step.

You can do the same thing with the top edge of the front view and the bottom edge of the top view.

By comparing this relationship with the answer choices , you can eliminate the rest of the wrong answers, like A shown below.

In just about every case, this process will eliminate all of the wrong answers. It is every helpful when you can't visualize the actual object. All you have to do is look down the edges and compare them. It almost never fails, but if you are going to use this strategy, you should practice lots and be sure that you know how to do it correctly or it will eat up a lot of time.

I am to the point where I can visualize the three dimensional objects for most of the problems just by seeing the two views, but this strategy never fails when I have a problem. Good luck!
 
I'd like to know myself,

But I actually plan to skip that section and randomly guess.

For me, its too time consuming. If youve got a grip on the other sections that could be a good idea
 
I had a tough time with this section at first, but after practicing a lot, it's gotten to be quit easy. I've taken lots of practice tests though... and at first I missed about half the questions in this section. I just took Topscore 2 and 3 though and got perfects in those sections.

My advice: keep trying - you'll get it.
 
I actually think that this section isn't so bad, it takes a bit of practice, but it does pay off. And when it pays off, it is so cool. So, I don't recommend anybody to blow it off. Study hard science for couple hours, and take a break to do this. Go outside to the sun, and work on these on the grass. Grab some Starbucks and do them. Listen to some music why doing them. These are brainless, so you don't need much thinking. However, as Thomas Edison would say... Genious is 99% perspiration and 1% inspiration. I think that is definitely true with the PAT in general.
