MathCADfor Dummies

I am (almost) a lone MathCAD user within my company. Due to the work I have done, I have been "asked" to do an intro presentation to my colleagues. Management does not want to spend money on the Mathsoft training until...I'm not sure what they are waiting on.

My question: does any one have a "MathCAD for Dummies" style ppt or worksheet that they would be willing to share?

Thanks,

Scott
