The same model as the last post with a reduced file size
To save buying the very expensive graphics card at this time, I reduced the poly (triangle) count on the model, this reduced the file size to the point where my existing graphics card can cope. In the future I will purchase a better one as my models are becoming more complex, therefore more graphic card memory capacity is required to rotate the model smoothly. But for now I can use what I have, plus I want to more research into graphics cards. Cad systems requirements are different to games requirement, direct x performance is important. The recommendations are for the workstation cards but they are much more costly than the Pc cards.
The file size reduction can be perform within many types of 3d Cad software, in this case I used Delcam Power-shape as I am using this to do the concept modeling
