3D Modelling Lesson 4 - Jetpack

Updated: Jun 12, 2019



The next model we were going to make was a jetpack. I started with a cube and a cylinder ether side. I found that making one pipe first then duplicating it made creating symmetry a lot easier. I went on to creating a cone and scaling it down to fit the cylinder, however, another way I could have created the pointed shape is by selecting the top face, having a very small offset and extruding this face into the desired point. Throughout the cylinder I extruded faces inwards to create indentations and to make the model more interesting. For the bottom of the pipes I extruded a ring of faces on the bottom to create the cone like shape and much like the cylinders, I added indents around the sides. As I wanted the pipes to have some sort of curvature in them and to be less straight, I added a sphere and scaled it into an oval shape which I also added round the sides. From looking at my reference photo I noticed that there was some bolts around the bottom and top of the cylinders which would have been to fit the three parts of the pipes together. I created these by adding a small sphere and duplicating it multiple times and placing them around in the selected parts of the pipe. Once I was finished with the pipe I duplicated it and mirrored it onto the other side of the base of the jetpack. For the base of the jetpack I added a pipe onto and extruded some faces to create a gear like shape but I thought this looked a bit bland so I added another pipe that wrapped around the gear shape on top and also inverted some faces so that it had some detail. For the front of the jetpack I added an oval and warped the bottom of it by moving vertexes and edges to get the unusual shape and once again inverted some faces to make it look like some sort of ventilation. Once I had finished all of the jetpack, I combined all objects and patched up any holes by using the target weld tool.


Overall, I am proud with how the jetpack turned out as it is very symmetrical and is easily identifiable. I didn't have many issues when making this model other then on the pipe some faces had lost its curvature however I couldn't figure out how to fix this.
