Birdhouse (free CAD download file)

Designed in Siemens NX8

Last few days there is too many splines in my life :) so I had to make something simple to relax a little. For no special reason I designed this birdhouse... it is more like bird hotel then a house. I hope I will have house with yard someday so I can make this in real.
Model if free for download, please send me images if you make this birdhouse.

Wind turbine (free CAD download file)

Designed in Siemens NX6

In the light of some recent events I just had to make this model of wind turbine. It does not have many details but it is good for rendering and maybe some simulations and analysis. Please note that this is not blade of real wind turbine, and that this design is not product of any math, this is just a shape that I found on internet and make it look little smoother, so any use of this model is on your own responsibility. If you find this model useful for some purpose other then making renderings please let me know, I will be truly grateful.

Parametric plane wing using wave linking, tutorial

Designed in Siemens NX6

This is tutorial for one of many ways to use WAVE linking in NX6. Idea was to make plane wing that can be changed with simple change of values in Tools>Expressions. I tried to make this from one part, but it is too complicated to be really useful, so I made it with assembly and wave linking to keep it simple and functional.

Gummy Bear model

Designed in Siemens NX6

Gummy Bear model. Designed as GRABCAD model request, using image below (brown bear on black background image). This is a model that would be much better if done in Rhino or 3D Studio MAX, but instead it come to me. I did my best to design it and it come out good but not perfect. I give up of fine tuning as some of surfaces I made for this model took more then 2 hours to update when edited, and that is just not a time I have to spend on this model.

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.
