This was a project utilizing Autodesk AutoCAD.
It's one of my favorite mechanical projects that I have done in this program, I find section views fun to make, despite the fact that it can sometimes be confusing to work with them at first. We started out by creating the 2D drawings(see "drawing preview"), then making a 3D model with copies of those individual elements, feature by feature. those 3D objects were then used to make the renders seen in the left and right images found below. Drawing set can be found here.
