Hey, I'm just wondering if any of you are into computer aided drawing. I had to take an engineering class, and we had to do some pretty extensive drawing on Autodesk Mechanical Desktop. The other sections got to use Solidworks. I've heard Autocad/desk is going out of style, and the our type...

this may seem quite stupid to many of you but i was wondering how it is possible to draw 4D objects. I have seen pictures of 4D objects such as the hyper-cube etc, but they are drawn in three dimensions. The picture of a hyper cube that i looked at seemed to me to just look like a cube with a...
