Hi and thank You for visiting my blog.

This blog is about my professional work, projects I have been working on, and some funny and interesting things about mechanical engineers. On these pages You can find some of my projects, as I work for army and I am not able to enclose all projects I have been working on.

My most recent designs You can find in posts below.

For more interesting projects You can follow labels, such as:

- aircraft engine blades

You can download some of my models, posts with files for download are labeled free model download.

or You can go to INDEX page and search through list of all projects on this blog.

Info about me is on ABOUT ME page, where You can see my professional CV and some info about my skills and professional knowledge.

For all questions about my work, projects, blog or job offers contact me over e-mail or Skype. E-mail form and Skype Add Me link are on CONTACT ME page.

For those who are interested in learning new stuff about Siemens NX program I made NX TUTORIALS page, where I will post some tips and tricks about how to use NX more efficiently.

Football ball, parametric model (free CAD download file)

Designed in Siemens NX6

Lot of designs done in CAD softwares are parametric models. It mean that model is defined by relationships, constrains and formulas, and that by changing one part of model you will change all parts that are somehow connected to it. Some of challenging models are those who are made to depend on only one variable parameter. I like to make that kind of design because it challenging, at least for me it is.
Here is a ball, with only one variable parameter "a", which is diameter of ball. On video you can see how it works in NX window.

stp file of 281KB is just a ball with separated faces and 25cm diameter (image of black and white ball), and 1MB stp file is more realistic ball with 3d shaped faces and 22cm diameter (white blue and brown ball images).
