Finally my test. All of the three figures failed.  They were not bending.  So I decided to take out of my design this type of texture.

I took a look at designs from the previous class.  Two of them call my attention because they use a cut in order to bend the wood.

This second attempt was completely worng:

Lines were not perpendicular, and some overlapped.

I really learned how to use the Trim function and the perpendicular lines in Rhino.

If there was something I learned to do in this assignment were the dog-bones figures.

The third attempt I tried to do something easier. But then I realize that this took two sheets of triplay therfore I decided to make something smaller if things didn't work out, at least I didn't use so much material.

  My last attempt was a small and simple table.

By this time I kwe perfectly how to use the trim option, and how to use press-fit joints really easy.  Also the dog-bone shape in every joint was something easy to do at this time.

Important things when you make a design:

1. When you join all the curves into a close curve do it line by line, in this way you will see if there are overlapped lines or open lines.

2. When you do a press-fit joint do it with a single line using the two bodies and then copy paste and use the trim option.  In this way you understand that one is the complement of the other.

3. In order to do the dog-bone shape first, use the curve --> line --> bisector, then measure half of the dimension of your cutter (cortador), then make a circle using as a the radius that line and the circle will come out of the original square, then trim. When you are done with one then use the mirror option.

4. In Rhino, use the options of perpendicular, midpoint, intersection etc.  so you know exactly where these points are, there are really useful.
