I'm a Pro/E...
Here's today's project (an in-line particle detector for oil lines). It's amazing what you can do with 3-D modeling. Many times, I've received prototype parts without ever creating a 2D drawing. I just email the file to the manufacturer and they convert to their native format and go.
One downfall is that people (sales, marketing, managers) see the images and assume the product is already finished. They often want fancy images for presentations. It's nice to take off the Mechanical Engineer hat once in a while, but when the wrong people see the images, it's hard to convince them that there's been no engineering involved in creating the image.
It's also too easy to create impossible to manufacture shapes.
I love my job, though!!
