ParticipantI believe the new version of AutoCAD can do 3D images, but SolidWorks seems to be more popular for this. I recently had a custom plastic knob designed, and the engineer who drew that for me used SolidWorks, which can generate .IGS and .STL files when can then be viewed with a free 3D viewer app.
Using the .STL file I was then able to have PolyJet samples of the knob made using a stereo lithography process. This only cost a couple hundred bucks and was a useful prototyping step.

Participant[quote=LuckyInOC][quote=sdduuuude]Very unlikely a heating element, but not because it is a short circuit. That’s what heating elements are – a short circuit.[/quote]
I disagree. A short circuit has O hms or almost 0 ohms resistance. A heating element has lots of resistance to produce heat. Opposite ends of the electrical resistance spectrum.
Lucky In OC[/quote]If a heating element had lots of resistance, it wouldn’t generate lots of heat. The more current that flows, the more heat that can be generated. But current drops as resistance increases. Therefore a heating element must have relatively low (but nonzero) resistance. Ohm’s law.
The reason it’s not a heating element, as someone else pointed out, is that there are no insulators suspending the crazy wire thing. If you connected those two big nubs to juice, electricity would take the easiest path which would be that big metal frame. If this was a heating element it would be constructed in such a way that the electricity would be forced to flow through all that convoluted wirework. But it’s not, which is why I claim it isn’t.
My money is on a rack of some sort, or the frame for holding a filter element.

Participant[quote=briansd1]If you travel overseas to some countries, you’d know that cash is still king. The money changers charge you more for travelers’ cheques, ATM or CC. You have to pay transaction fees, conversion fees and commissions if you don’t use cash.
When I travel I always take crisp 100 dollar bills with me.[/quote]
This doesn’t help you. You generally can’t spend your Benjamins abroad, and the moneychangers charge exorbitant rates to convert that to local currency.
By FAR the best bet is to use an ATM card, and withdraw as much local currency per transaction as your bank allows. You get the overnight exchange rate, plus a flat fee – generally 5 or 6 bucks – which when amortized over the 300 or 400 you withdraw, is a FAR lower vig than what you’d pay trying to change a $100 at Thomas Cook.

ParticipantActually, I’m more appalled by the totally ghetto chain link fence surrounding the McMansion for sale across the street.
