This is Fusion 360. The profile was drawn and various measurements parameterized (shown in the listbox on the lower right). That means the measurements were given names (e.g. body_diameter, thickness). This makes it possible to change aspects of the geometry of this shape by just editing the parameters. If you are experienced in 3D CAD you will be able to see this drawing is actually beginner-level, I have not fully defined and constrained it. For example, I cannot change the height or width and have it maintain the shape when it redraws (to do the z-axis value of the vertical center-points of the curves need to be defined as a percentage of the neck height, and the neck vs body height proportion also needs to be set). I should also have placed the center of the lip at the origin. Further, it does not need to be hollow, it should be a solid body enclosed by the desired profile.

3D Design
3D Design software is used to create dimensionally accurate objects by sketching 2D geometry and transforming it using tools to rotate, extrude, sweep, etc. The software generates the polygon surface. |
