Maybe I shouldn't have started this blog now, not with everything that's been going on.

In my Graphics Two sessions on the third day of the fourth week of classes, I introduced some, if not most, of the class to hidden lines, which represent edges existing in the figure but are not visible in one of the orthogonal views.

There is a specific length to the segments and the spaces of this broken line.

At the same time I told them how to put dimensions in their drawings, imagining that they are going to ask a carpenter to construct the figures they are drawing.

I did not ask them anymore to draw any samples before they proceeded to the three plates, since by that time I was already assuming that they knew how to get the orthogonal views based on the isometric representation from our twelve previous examples.

Some who still could not get the practice completely I asked to bring cardboards or Lego blocks to the class to construct first before looking at the orthogonal views physically.

Again the students from the 11am class arrived early, so there was no time to give them different figures to draw.

I threatened to talk to their Intermediate Computer Programming lab teacher to give them more difficult exercises next time so that they would consume the entire period in that subject.

Even though I already allowed them to print out or photocopy templates of the paper to be used with margins (no letterings though, that still had to be written by hand) the copier being broken forced them back to making the margined plates by hand.

One girl showed a plate with blue margins, because, she said, the blank ink of her printer was all out. I allowed that.

I still admonished some students who consistently forgot to bring their own erasers and constantly borrowed from others. Maybe I will inspect everyone’s materials next time.

On the other hand, when I passed by the cafeteria after stepping out of the second class for a moment, I saw one student enrolled in my class hanging around there, because he said he did not bring his drafting materials.

That’s not an excuse, I said, because there were several people from the earlier class he could have borrowed from. Besides, was that reason enough to miss three plates?

Session 795 submits requirements at this point, and may now leave the room. Class dismissed.
