Designing an hourglass by Solidworks is so easy:
- Create a 2D Sketch on Front-plane.
- Start drawing a glass profile on the plane.
- Use Revolve Extrude to create a glass.
- Then make a new 2D Sketch on Top-plane for drawing a lid.
- Draw a circle on the Top-plane Sketch.
- Create the lid via Extruding the circle.
- After that use Mirror feature to make the copy the body in other side.
- Now you can create a support.
- To have three supports, use Circular pattern.
- Finally filleting edges.
