Question: "If you look at it from the side, wouldn't B be correct? I looked at the 3D visualizer and it looks like answer choice B."

Answer: I have gone ahead and created an image for you that shows the correct size and dimensions of the three views. I have also brought in the side view right above option B so that you can easily compare the two. I hope that helps you see why B cannot be correct.

I will also attach an image showing the reference points for the viewing angle. The blue lines represent the front view and the green lines represent the end view.

Question: "It seems to have either the wrong answer or no right answer. The correct answer has a gap that is thinner than the picture. Can you help?"

Answer: You cannot measure the lengths on the given view and compare them on the answer choices. This is innately inaccurate and will result in measurements that are often, never right. Sometimes the measurements are extremely close due to the angle that the figure is viewed from but other times, it can be off. However, the proportions will always be accurate. So if you really want to test out an option choice, you can measure a few different features on the given object and obtain their ratio. You can then do the same with the option choice and you will find that they will match. However, upon reviewing question #7, I would say this is actually one of those times where the measurements are pretty much identical. This is a difficult question but essentially, you chose the wrong axis of view for the figure. Let me explain.

Given the irregular shape of the figure, we have options as to how to view the figure and align it with the 3D coordinate plane. I have outlined two plausible alignments below with red and green arrows. You essentially chose the green alignment and correctly concluded that the gap should be wider. This would have been correct if one of the option choices reflected this, however, the option choices have all been derived from the red alignment instead which results in a front view that matches option B, the correct answer. I hope this helps!

Question: "How can you tell the below:

1. The rectangular box is taller than the cylinder?

2. When looking from the left/right projection, the rectangular box looking thing is actually shorter than the cylinder?

3. Also, how do you know that the space between the cylinder and rectangle will be large and not small?"

Answer: We are able to tell that the rectangular feature is taller based on the relation to the base as seen in the image below with the green and red lines.

We are able to tell that the rectangular feature is 'shorter' as you have said, based on the relation to the base and a few true lines that are given to us. Please see the image below with the yellow and green lines.

As for the space between the two features, you again must use what is given to us. In this case, I used the width of the rectangular feature to ascertain the location behind the rectangle that space would begin. I then drew a line to the circular feature. Please refer to the last image with the purple and blue lines.

Question: "For Option C. I'm having a difficult time being able to tell that the length of the object is not the same as to the 3D image. Are there any quick tricks to fixing this?"

Answer: This is certainly a challenging question. Have you had a look at the 3D model? You must compare the lengths with other features. For example, on the 3D figure below, you are able to easily see that the green arrow which represents the width of the middle triangular extension, is shorter than the red line which represents the remainder of the edge when the object is viewed from the front view. On option choice C, the triangular extension is shown to be greater in length than the remainder of the edge. This was the give away here.
