    Synthetic Gasoline is coming???

    Evelrod, you've hit on a big part that a lot of the people who promote widespread homemade bio-diesel always seem to gloss over - how much of their own time is spent making it. I like to make my own beer, and my friends always ask 'how much does it cost'? I tell them that for all of the...

    Education Improvements?

    I think one class that every single engineering program should teach is "practical problem solving". An Engineer's whole job is about solving problems, and many Engineers' first exposure to actually solving a problem is when they get their first jobs. If they have a good boss/mentor, or they...

    3D CAD of chassis and components

    "Has anybody had much experience with 3D scanning for this sort of end use..." "scanning would be a good start for CFD work as you are generally just concerned with the outer surfaces, but as I am interested more in the structure, 3D scanning will be a bit more difficult." Are you interested...

    3D CAD of chassis and components

    I assume by FE you mean Finite Element Analysis? This month's, or maybe last month's issue of Racecar Engineering has an article about using scan data for CFD. They were scanning an entire race car and using that to determine drag, downforce, etc. It should be a good starting point for seeing...

    what's the difference between the DTEXT and MTEXT command in AUTOCAD

    I haven't used Autocad in a long time, but isn't MText used for multiline text and DText is only single line text? Have you tried using Google or the Autocad help files?

    catia v5 drawing-dowel hole?

    I'm not sure, but could you add a custom hole to the "hole" creator that has all the callouts for the dowel you need? I haven't tried it, but that would be my guess. I think you just have to edit an excel file or text file. Bob

    'Educated' opinions on climate change part 2

    Unotec, Your argument doesn't hold much water because making an accurate prediction of the day to day weather for a week requires incredible amounts of precise and accurate data for a huge geographical area (local temperature, wind, humidity, cloud cover, solar inensity, and more data for the...

    'Educated' opinions on climate change part 2

    ElectricPete, To answer your question "why is it that this subject has not been revisted by Jaworowski in peer-reviewed literature since 1994", in an article about Jaworowski and his research: "Because of the high importance of this realization, in 1994 Dr. Jaworowski, together with a team...

    New Auto Manufacturer

    Ksor, yeah, all those companies I mentioned are low-volume sports cars. I'm betting that the profit margin on a "normal" car would be too low to justify the investment to set up the company (not to mention establishing a dealer network, etc). Besides, I'm betting that 99.999% of the people who...

    New Auto Manufacturer

    For the US market, look at the attempted comeback of Cunningham (was it Lutz or Iacocca who was involved in this - I can't remember), Shelby's Series 1 debacle, Qvale, and the myriad other failed small car companies and try to figure out why they failed and whether it was related to finances...

    Parts Missing after Step File Creation

    If DBezaire's recommendation about changing your settings doesn't work (although I'm betting that is the problem), how large is the STEP file? I've had problems importing into Ideas when the step file was larger than 40MB. You can read where I asked about it here...

    'Educated' opinions on climate change part 2

    Allow me to bastardize Mr. Newton's third law to show my view of the Global Warming debate: "For every argument, there is an equal and opposite argument". Petit et al (in ElectricPete's "picture is worth a thousand years" post above) say that CO2 is going up dramatically and have the ice core...

    'Educated' opinions on climate change part 2

    Here is an example of why I have trouble believing that man is the reason for global warming (ignoring the argument regarding whether warming is happening or not): http://www.canada.com/vancouversun/news/story.html?id=8ffa0bd4-2aa3-4c0e-82de-f45972f014cc Part 1 of the article details how the...

    Data migration from Ideas to Solidworks

    Hi Christophe, There are several companies that offer both feature based and non-featured based, automated 3D model translation software or services. The problem you may run into is that very few people offer support for native Ideas files. There's something about that software that has scares...

    What will the price of crude bring next....shale oil?

    I actually heard a US national news reporter mention "a new record in the current oil price bubble" last week. I thought it was interesting that a news program was going against the grain and called it a bubble instead of having the typical "oil prices will hit $113532/barrel by Christmas"...

    Drag vs speed curves available for modern cars

    Car and Driver magazine (I think that was the one) used to and may still include this in the 'specs' page of their road test reviews. Try looking in there. I'm not sure where they got this number from, whether it was from their own testing or from the OEMs. Bob

    Orientating model

    I've been using V5 for years and had no idea you could do that with the compass! Thanks Azrael. Bob

    Graduate School

    I'm 32 and am going back to school full time in the fall to get my MS. Do I wish I had done this many years ago? Yes. Do I wish I had done it straight out of university? No. While getting my BS, even with a lot of co-op experience (my school alternated 3 months classroom then 3 months work...

    lambda problems

    How does the specific output (hp/L) of an engine have any bearing on the need for a wide band lambda sensor? A wide-band sensor will allow you to get an accurate reading of your air/fuel ratio over a wide range of a A/F rations, unlike a typical lambda sensor which basically is only good for...

    Design of Adjustable Spoiler to Reduce Drag and Increase Downforce

    The Porsche Boxster also has a pop up aerodynamic device, I guess spoiler is maybe the best thing to call it. Going from memory its about 60mm across, and extends about 10mm up from the rear at about 100-120kph. It slides out from just behind the rear decklid rather than the 911's pop up wing...
