Solidworks tutorial using sweeping tool to make simple bottle

free solidworks tutorial
Solidworks  Sweeping Tool :
can be simple or complex. For example, the spoke of the hand wheel in the illustration  is swept using a 2D sketch for the path and an ellipse for the sweep section. The sweep section does not vary along the length of the path. Sweeping can be much more complex than this simple example. Swept features can also incorporate.
Dimensional curves or model edges as paths, and the sweep section can be made to vary as it moves along a set of other curves called guide curves.

Sweep Components
solidworks tutorial
Below is a list of the major components used in sweeping, including descriptions of their functions.

1. Profile.
Sweeping only supports a single profile sketch. It must be a closed,
non-self-intersecting boundary. However, the sketch can contain
multiple contours – either nested or disjoint.

2 .Guide Curves.
Sweeps can contain multiple guide curves which are used to shape the solid. As the profile is swept, the guide curves control its shape. One way to think of guide curves is to visualize them driving a parameter such as a radius. In this illustration, the profile is attached to the guide curve. As the profile is swept along the path, the radius of the circle changes, following shape of the guide. in solidworks


 3. Sweep Path.
The Sweep Path helps determine the length of the sweep by its
endpoints. This means that if the path is shorter than the guides, the
sweep will terminate at the end of the path.

 Case Study Bottle:
in this solidworks tutorial free
Modeling free-form shapes requires some techniques for creating features that are quite unlike the extruded or revolved shapes built in the basic solidworks tutorials . This example will go through the steps of creating the Bottle solidworks 3d model

Stages in the Process:
in  solidworks tutorials free
  • Create the basic shape of the bottle. This will be done by sweeping an ellipse in such a way that the major and minor axes will be controlled by two guide curves.
  • Add the neck. This is a simple boss extruded upwards from the top of the swept body.
  • Shell the bottle.
  • Model the threads.
  • This is another sweeping operation. However, this time a different sort of path is used: a helix.

Successful completion of this solidworks tutorial, you will be able to:
  •  Create a shell.
  •  Create a non-planar curve by projecting a sketch onto a surface.
  •  Create boss  sweeping.
  •  Model threads.
