Welcome to the fourth part of the "Building a boat" tutorial.
Chapter 2 - Building a polygon boat
Part 4 - Connecting the bars
Unfortunately, this is going to be a very looong process. There is almost no way of skipping it, if you want the model to look top-notch, but hopefully the video attached to this article will make your job easier.
This is the link to the video tutorial of part 4 - http://www.youtube.com/watch?v=aLjhCn2QLsY
Again, there is not much to say here. First of all we will want to make all the tubes hollow inside, so we're going to select all the faces at the end of each tube and delete them (be careful to delete only the faces). This process is shown at the beginning of the video.
After managing to do that, it's time to start connecting the tubes. This tutorial is made using Blender, but the other software should have the following options too.
Remember what you did at the end of part one when working at the cabin roof and how you created faces between the vertices? This is basically it. The only difference is that this time you are going to select each individual vertex at the end of each tube and connect it to the one of the next tube, this way creating new faces that connect one bar to another.
This is going to be a very time-consuming task, but at the end of it you will be happy with the results.
Just as a little tip (not shown in this video), instead of selecting individual vertices to form a face (4 required), try selecting the edge at the end of which are two vertices. This way you will only have to do two clicks (one for selecting each edge).
