We have four boxed copies of AutoCAD 2008 Mechanical (individually licensed). We're adding a fifth person to do CAD, and now I need to source another seat. I'd like to keep everyone on the same version for a few different reasons, and upper management isn't convinced that we should upgrade...
Half way there:

A default member allows me to declare the value, but I still don't see how that would allow me to operate in a non-trivial fashion (such as with matrices or complex numbers).
Think of this small example.
Dim dblA as Double
Dim dblB as Double
Dim dblC as Double
dblA = 2
dblB = 4
dblC = dblA + dblB
MsgBox dblC
'Returns 6
I want to write my own data type class to handle numerical data of a different type, such as with complex numbers or high-precision floating point...
I'm going to propose an automated method of generating our annual product catalogs. A polished system ready for production would help my proposal tremendously.
In our primary catalog, we offer products of a few dozen types with tables of the available sizes. For each product type, we have 3D...
How about an o-ring seal below the threads? Putting the o-ring on its own shaft would prevent extrusion through the threads. The installation chamfer is important here too.

I'd go with either a PTFE cap seal energized by an o-ring or a single-acting rubber u-seal designed specifically for pneumatic piston sealing. Don't rely on seals to act as guide rings. There are guide rings available in PTFE, and depending on the size of your piston (and the resulting pressure...
What I may end up doing is making "fake" 3D plots by drawing the 3D views in 2D, either orthographically or by using trig. I can probably simulate polygon shading by making solid hatches. I was hoping to avoid this because we have a lot of drawings that would have to be converted in this...
I'm trying to put diagrams and pictures into a Microsoft Access report so I make a nice PDF for eventual mass publication (after some doctoring up in InDesign). The final resulting PDF will be widely used by customers and coworkers, and it will see many downloads from our website.
Right now...
I think my chances of passing the general test or the mechanical test are almost even, leaning a bit toward the general side. I've been out of school for about two and a half years now, but I'm a proficient self-learner, and I tend to read a lot of geeky stuff both in and out of my field. I'm...
If there's little profit in it, perhaps you can over-engineer it with an extra factor on top of what you're already going to use and just use the endurance limit. I'm more of a plastics guy to be honest with you, though...
We bought some cheap Asian parts machined out of steel, and since I was jointly responsible for the engineering, I drew the short straw to work on the first article inspections. The parts are made of chrome-plated steel. The machinists left quite a few shavings along with a lot of oil inside of...
The force required to accelerate a heavier con rod will balance the pressure load of the piston and help to eliminate failure in compression (but it will make the tension problem worse while the cylinder is being filled/emptied). Whether this is good or bad all depends on where your torque is...
If it stores electrical energy that was previously generated from renewable sources (i.e. solar, geothermal, etc.), it's already ahead of fossil fuels (to an extent). I don't see enough of an energy density to be worth a darn, though. This is competing with Hydrogen, methanol, and other carriers...
