I'm learning to use Inventor 2008 and 2009 and I have a question concerning materials on both versions. I notice that you have pre defined materials that you can apply to whatever part you're working on but I'm not sure how does it actually works in the program itself specially on those cases...

I have a Dell Precision M6300 with a CAD certified NVidia Quadro 1600M and Windows XP. When I was shoping for a new laptop from a Toshiba Satellite I considered the HP M90 but changed my mind to the Dell Precision due to cost considerations. I haven't regretted it so far. First computer that I...

Is there a formula for calculating the thickness of a piping blind (i.e. Flange, Fig 8, line blind, etc) ? If so, what is the appropiate formula for each type? Carlos

gcomyn: I have used PIPE-FLO most of my piping design life. I have lived it from the DOS version 3.0 up to the latest version Professional 2007 and I´m very happy with it. It converges on large networks very fast and it´s very precise. It takes some time to get accustomed to its interface but...

Piping and plumbing design is based mostly on rules of thumb and careful analysis of the system operating conditions (pressure, flow). A good starting point is reviewing old drawings but that is not the answer to all the questions that you may have. Good piping design usually comes after some...

I'm trying to determine an Autocad drawing's creation date but I have a question: How can I determine the true creation date for a drawing created using imported drawings from a diferent file? I.E. If I copy some portions of another drawing and then import it into a blank drawing is there any...

Thanks, it worked!!! Carlos

I did what you suggested and I got Mathcad installed on my Windows 98SE desktop. But couldn't on my Windows XP laptop. I changed keyboard language and regional settings on the control panel for windows XP. Maybe if you tell me with some more detail what sections should I change in addition to...

I have Mathcad 2000 which I purchased on a trip to the US. Trouble is that since I live in a foreign spanish speaking country I can't install it on either my laptop with Windows XP Home nor on my desktop with Windows 98SE. It gives me the message that it is for sale only on the US and Canada. I...

I have a question: Are pipe flanged spools between the outlet/inlet tank valve and the tank itself allowed? If not, what is the reason? Carlos

What is the correct method in determining a pipe retiring thickness?

I do agree with you that some things require a monopoly and in the case of computer OS systems I do agree with you also. But the thing here is that whomever the monopoly might be in something like OS systems, the least that we could expect as customers from this monopoly, is a well finished and...

I have a question related to a welding procedure for welding the wall shell plates for a small 4000 BBLs water tank. Material of the wall plates is ASTM A36 1/4" thick 3 by 6 ft and the welding procedure calls for using welding electrodes A6010 for first pass and then A7018 for second and...

Is there any information (articles, freeware, worksheets, design data, etc) available on how to calculate a hot buried pipeline temperature profile? Your help is appreciated Carlos

What is the recommended piping deflection to assure adequate drainage of the piping? Is there a practical rule of thumb? Carlos

Microsoft has never in the life of Windows 98 given any decent software support (and neither for other software products as well). Basically all they have done is publish patches to mend all the loopholes and bad programming embedded in their products. Of course, they are really happy publishing...

Has there been REALLY any time that Microsoft has ever given appropiate support to ANY version of Windows? Lack of support for Windows 98 from MS probably will go unnoticed except for third party dwindling available software applications that will make use of it.

Where can I get a commercially made vacuum box test rig and what is the approximate price for it? Also what is what you call the chalk test? Thanks for your help Carlos

The idea of having one single source for your OS seems great if only the OS manufacturer behaves transparently and very strightforward in their support of their environment for developers of third party software. But the thing here has been a very predatory MS on everybody that dared to create...
