What productivity tools does Engineers use when designing in CAD?

I'd be totally 100% lost without my 3DConnexion SpaceExplorer! Being able to manipulate my models in Solidworks with the SpaceExplorer saves *many* mouse clicks and toolbar visits to achieve the same effect! In fact, I don't know how users cope without using one!! Having employed a contractor recently to help on a design, it was both amusing and frustrating to watch him explore the model he was working on for me, feverishly clicking toolbar buttons and dragging the mouse around...

i agree with Manolis.i just concentrate on my work by listening to music in the background.

Machine Design data book.

Music. I function better with my favourite music in the background

I use a 3D conncexion SpaceNavigator. Helps me work alot faster when doing assemblies and stuff like that where you turn the model around all the time.

I use Mapkeys in Pro-e.....they are very effective and will definately increase your productivity.

My 3D Connexion Space Pilot is a great tool, BUT, dual monitors is such a major productivity booster for me...I would not survive long without it. :-)

Learn the keyboard shortcuts, remap them if needed, and ditch the 3D mouse ;-)

Excel. This is the software to make simple designs expand into product lines.

Essentials are:

Roark's formulas for stress and strain
Mathcad
Excel
All applicable industry standards (ISO, ASME, API, ASTM etc)
Big stack of scrap paper

Second monitor, the s button in SolidWorks, right click to complete a feature in SolidWorks, good music

Numeric keyboard.
This it's my favorite gadget.I use numeric keyboard for shortcuts,for example '+' for Boss Extrude, '-' for Cut Extrude, '5' for Circle, '4' for Line, '1' for Copy, etc.
