Dermot, Try these: 1) The reason you have a distorted box is simple. You put the vanishing points close and spread the drawing out beyond a normal cone of vision. That’s an old lesson. 2) Same reason, (but also see 3) 3) Yes, but you have five divisions on the Measuring Line, four on the projected set….

Dermot – I'm not sure what you're referring to. No "blue wall" at 6:50 — that's the measuring line! But yes, after establishing a two-point ground plane, I created a third point to give the height some oomph, and that should be no mystery to you by now. In the first half of part one we learned that the third point is a choice. I exercised that choice. You did not, as evidenced by your next post...

I didn't explain because I devoted all of the first Premium to that! Take them in order. We're parsing this out, partly so that you can assimilate the lessons of one before moving on to the next.

Carlos - if you are finding it "easy and natural to use one method and directly start constructing with another one," you are in such a good state of mind that not understanding the difference between the first two is hardly an issue. Attempting to explain in words, like "X's divide in halves; diagonals extend as 'one leg of the unknown X'" may just confuse you more. If you care , go back to the lesson on Diagonal Finds Far Corner. But if you can use these methods as freely and naturally as you are here, don't worry. Just draw.

We could invent one! Let's consider...

Aside from doing them freehand, the only specific problem I see is how you handled the bases of the columns in 02. Those require attentive construction per base. They are blocky, but they have different sized top and bottom-planes, connected by concaves like in the anvil drawings, and that takes extra work... per block! The other issues, like the bending verticals in 01, may be solved by using tools. Don't feel guilty. Freehand is an end-goal that you can practice separately. This part is about learning the procedure. But Carlos — I admire that you were willing to try these freehand. Go to the tools to take care of the "control issue," and to understand the moves well enough to take comfort in that.

If you can draw what you're trying to do and post it soon, I'll try to get to it for the coming crit.

Dennis - remember the secret of overlays: vellum is one way. Another is to work lightly with erasable colored pencils, then do the finished lines with something less erasable. Etc. There are ways...
