McMaster-Carr has a gizzion parts in their catalog. Rather than use an internal company part number, ex. 123456 for a part and then reference the McM part number, has anyone used the McM part number itself?
For example, one has a bolt with a given thread, material and coating. What if you...
I downloaded a 30 day trial of VX Innovator CAD to have a look-see. I haven't found much in the way of online forums.
Anyone use VX for general mechanical design/drawing CAD use?
Any opinions/advice would be appreciated.
Thanks!

With regards to an AC electric motor, if the locked rotor amps (LRA) are known, can one expect the inrush current at start-up to be higher if the motor is starting with a load present vs unloaded? How would this be same/different with a single vs 3 phase motor?
Thanks!
Bill
Take my suggestion with a grain of salt as I am no SW or vault expert - but here is what I am trying with an assembly of mine.
The assembly is a 3D assembly of an electrical device. It was downloaded from a vendor as a STEP file. Via SW Explorer, I renamed the assy, but not the sub assy and...
My computer is an HP Pavillion laptop with an AMD Turion 64 processor. It has 1 gig of ram, Windows XP media center edition and an ATI Radeon xpress 200 IGP graphics card with 128 MB video memory.
I've had it for just over 3 years and it has been a great computer.
We're getting ready to load...
I'd like to do the home install, but the $$$'s for a suitable PC (and in my case a laptop pc) is a show stopper. That's why I use AD now.
What I'd like is something with a richer set of features than AD, but with an AD price and will basically work on a gaming PC.
Thanks & have a great...
I use SW on my day job and Alibre (AD) on the side. While I like AD, my opinion is they are slow to implement enhancements that have been in SW for years. Recently, they dumped a nice file management system for something I regard as very complicated for a one man operation.
Another nice thing...
I have an electric heating strip. Let's say the heater's watts is 1000. The voltage is 208. From W=(V^2)*R, I determine that the resistance for the heater is 43.26 ohms. Is this correct?
If I change the voltage to a higher or lower number, does the resistance on the heater stay constant...
"Is this to assess for potential hearing damage, or public nuisance?"
The sound measurements are to find out the decibel levels, compare them to known db levels and finally try to figure out some upper limit so as to not have a public nuisance with future outdoor concerts.
Thanks!

I need to know the basic differences between A vs C weighting when measuring sound. I am measuring sound for an outdoor event and in my searching I find a lot of stuff for A-Weight, but little on C-Weight.
When measuring sound with the above weighting, when would one use slow vs fast settings...
Back in my old days of Unigraphics, there was a command similar to SW's hide and show commands - except that all items that were hidden, at the click of a button, would be shown and all items that were previously visible were hidden. Sort of a reverse hide/show command. In UG, I believe it was...
I am considering the following refrigerants for a high ambient application - replacing R-22. This is a new design and I can select what ever refrigerant I want, so long as it is a non-ozone depleting refrigerant.
I gather R-410a is a suitable replacement for R-22 and better in performance than...
What are your opinions of using Schrader fittings on a R-410a system in general and more specifically for a place to mount pressure switches vs brazing. The idea is - in a tight package, it is easier to replace a defective pressure switch that's fitted to a Schrader fitting than tear the unit...
