The reason we do the work - all of which are exercises - is to learn and grow. While plenty of students share in your anxiety, it's because students tend to care about the end result, they put pride in the end result, and if it doesn't turn out as they'd hope it would, they feel that reflects badly upon them. But the end result doesn't matter, all it does is mark the end of the activity, the exercise, the process where learning and growth actually occurs. It's the prescribed process that matters, and that comes down to a simple truth: if you follow the process as intended and the result comes out poorly, you've done a good job. If you don't follow the process as intended and the result comes out well, you've done a bad job, because the purpose of the task was to do it in a certain way.

All that said, your work in this lesson is actually very well done. I'm not saying that to make you feel better though, rather to illustrate the fact that how you feel about your work simply isn't reliable. It's always going to be caught up in those misguided ideas of integrity, and the apparent need many students have to, in the absence of actual knowledge of whether or not what they did came out well, assume that it didn't. A student who assumes they did something poorly when they didn't is no better off than a student who assumes they did something well, when they didn't. Honestly, the latter case implies a greater degree of self-confidence, which might give them the edge.

Anyway! Jumping into your form intersections to start, as it stands you are further along than we generally expect from students at this stage (we expect them to be comfortable with intersections involving flat surfaces, but to still have trouble when curving surfaces are added to the mix). There are certainly some issues that I'll call out, but as a whole you're progressing well. Here are some mistakes I noticed on your first page. Some of these are nitpicky (where the intersection lines need to be more curved to properly adhere to both surfaces simultaneously). though others are cases where you may want to pay closer attention to the specific surfaces that are involved in each intersection (intersections occur in pairs, although a single intersection that crosses many surfaces will be broken down into separate sections). It's easy to end up guessing at how an intersection usually would go given a particular pairing of forms, but given that there are so many ways two surfaces could ostensibly intersect, it's always necessary to look at what's going on, and actively avoid giving into the temptation to make an educated guess.

To that point, this diagram talks more about identifying the individual surfaces (for example, looking at how the side/top planes of the box illustrated there dictates which cross-sections of the sphere we should be paying attention to). It also tries to explore curved intersections a little differently than you might consider them now, by explaining them in terms of being a transition between two different surfaces (similarly to how an edge denotes the border between surfaces that are oriented differently), but where an edge is sudden, a curve is itself a gradual transition spread out over a larger distance.

Anyway, this exercise comes back up in Lesson 7, and as it stands you're still ahead of what we expect to see, so keep working at it and try to incorporate what I've explained here, and we'll take another look when the exercise comes up again.

Continuing onto your object constructions, these are honestly really well done. You've adhered closely to the principles of the lesson, which focus on how we can increase the amount of precision in our process to more directly control the results. Precision is often conflated with accuracy, but they're actually two different things (at least insofar as I use the terms here). Where accuracy speaks to how close you were to executing the mark you intended to, precision actually has nothing to do with putting the mark down on the page. It's about the steps you take beforehand to declare those intentions.

So for example, if we look at the ghosting method, when going through the planning phase of a straight line, we can place a start/end point down. This increases the precision of our drawing, by declaring what we intend to do. From there the mark may miss those points, or it may nail them, it may overshoot, or whatever else - but prior to any of that, we have declared our intent, explaining our thought process, and in so doing, ensuring that we ourselves are acting on that clearly defined intent, rather than just putting marks down and then figuring things out as we go.

In our constructions here, we build up precision primarily through the use of the subdivisions. These allow us to meaningfully study the proportions of our intended object in two dimensions with an orthographic study, then apply those same proportions to the object in three dimensions.

Your orthographic plans and your use of subdivision adhere very closely to this, so my critique isn't really going to be calling out mistakes. Instead, I wanted to make a suggestion that might make certain kinds of constructions easier.

A number of your constructions feature components that don't necessarily always sit at the same angle to one another all the time. For example, where a table is generally going to have legs that sit perpendicularly to the tabletop (or if it's fancy, maybe they're set at an angle, but that angle never really changes in its use), other objects - like these glasses, which have three components (the main part of the frame containing the lenses, as well as the two arms or "temples" as they are apparently called), feature elements that could ostensibly be at a wide variety of angles to one another. Sure, the glasses have a fully "open" state where the arms' hinges are as open as they'll get, but when you have a pair of glasses sitting around, you'll often find that the arms are set at angles to one another.

Constructing such an object with a single bounding box has its advantages - it allows us greater overall control of the proportions of different aspects of the object in relation to one another, but that comes at a cost. Any subdivision we add has to stretch across from where it may be relevant, across places where it may not be relevant at all, and where it may increase clutter and confusion. In addition to this however, it also lends itself much more to setting objects at 90 degree angles to one another (although in the case of your glasses, your arms weren't entirely perpendicular to the central part of the frame, but achieving that definitely took a lot more work from you). This can result in the object potentially feeling overly stiff and unnatural.

Ultimately every technique we learn is a tool. It's up to us which tools we use, based on which concepts those tools prioritize, and whether or not they align with our own priorities.

So, an alternative option here is to create three distinct bounding boxes - one for the central part of the frame, and one for each arm. These would be free-floating boxes constructed separately from one another, more similarly to how we approached construction in lessons 3-5, where we built things up from the inside-out. This limits our control over those proportional relationships, but in cases where the proportional relationships don't have to be anything too specific, it can definitely save us a lot of complexity.

Arguably the stapler could also benefit from this, but given that the stapler does have a very specific "neutral" position, and the top section only pivots when it's in use, the way you approached it with a single bounding box still likely would have been the right choice. But of course, "right" is subjective - it's all dependent on what problem you are specifically attempting to address.

Anyway! All in all, very solid work. I'll go ahead and mark this lesson as complete.
