I haven’t use the engineering design tools for a even long time since I graduated at 2003. My major in college is Mechanical Engineering. I’m not good at the tolerance and axletree. So I learnt the IT myself at Grade 2. But I’m much interested in design, both the engineering design and the art design. I borrowed books about photoshop, flash and 3Dstudio from our Lab. The ProE is a course of Mechanical Merchanism that taught at Grade4. So I feel much genial of this software.

I’ll try to design a figure by it later.
Welcome any suggestions if you are interested in ProE too.
