Time for action — setting up the boom and gaff so they swing
Now it's time to assemble the sloop. In addition to just bringing all the parts into the same file there are a couple of other things that need to happen. Some of the parts need to have the materials from the hull and the cabin added to them, and all of the parts must have their relationship to the hull defined. Either they will be joined to the hull to make one solid object or the hull will be parented to them so that it controls their actions. Objects that are fixed, such as the cabin, will be joined to the hull. Objects that move, such as the rudder, will have the hull parented to them. If you wish, you may assemble the parts that you have made in lieu of using the files I have provided:
