MATLAB Spring Designing Source Code

The MATLAB source code is for designing springs under static pressure load. User choose spring wire material, wire diameter range and load properties. And then by running the code, spring diameter, spring index, effective turns, critical length and pitch will be determined. The code also supports spreadsheet output.

TomyadAuto® Fedora Concept

Fedora is based on a new way of sketching and designing using SolidWorks. New kinds of material property are used for rendering.

Using SolidWorks to design an hourglass

Designing an hourglass by Solidworks is so easy:

1. Create a 2D Sketch on Front-plane.
2. Start drawing a glass profile on the plane.
3. Use Revolve Extrude to create a glass.
4. Then make a new 2D Sketch on Top-plane for drawing a lid.
5. Draw a circle on the Top-plane Sketch.
6. Create the lid via Extruding the circle.
7. After that use Mirror feature to make the copy the body in other side.
8. Now you can create a support.
9. To have three supports, use Circular pattern.
10. Finally filleting edges.

You can download hourglass sample file and open it by SolidWorks 2009 or higher version and then viewing tree-view to see the design elements and their structure:
