Is this the correct usage of multiple Datum Reference Frames? I don't really want to use multiple Datum Reference Frames but I don't have a choice in the matter. I have to make the best of this. How can I best indicate the toleranced distance between the two datums? A PDF is attached if that...
I am self training on GDT. I need to use it so that I maintain that the two holes below line up. Is this proper use of GDT for non-opposed diameter of the same size. It has implied self-datum according to a GDT book I have but I am unsure if my interpretation is correct. Please verify...
KeyCreator and Cadkey do not output PDF files or any other file type that allows selecting of the text on the page or sheet. Is there a way to output a file of selectable text? Basically, it is like the text drawn rather a font.
If I can get to selectable text, I can make our 5000 legacy...
I am struggling with dimensioning and tolerancing especially as it relates to injection molded parts. I always strive to be one of the best at what I do. However, this area seems to keep causing me to stumble.
This is the process I go through and where I struggle:
1. Make a drawing of a 3d...
In 2d drawings, does a centerline always require symmetry in rectangular parts? Can you use centerlines in quasi-symmetric parts (see picture below)?

I am making building layouts of the interior space of warehouses. This show's us the available space for installing equipment. I have no background in doing this but I have background in CAD.
I walk into a warehouse with a tape measure and a pad of paper to make sketch the layout. What are...
I am an entry level engineer. As an exercise, I was asked to confirm an orifice plate sizing calculation using International Organization for Standardization (ISO) 5167-2. The gas is natural gas with the following composition:
Methane, CH4[tab] 98.26%
Nitrogen, N2[tab] .79%
Ethane...

The tank size and configuration is fixed. The inlet of the water is fixed. The water level needs to be maintained at 2500 gallons by a float valve or some other control. The float valve or control must be in the tank. The fluid is demineralized water at 180F +-20. See picture below...
I am trying to run a line body model with different members having different cross sections. Are any of you familar with the Line bodies and how to allow them to have different cross sections?

I have a sheet that calculates PV given the variable i. However, I need to run through many values of i. I need a marco that runs through a loop for given set of i values and calculates PV. Does any have suggestions on how to do this?

Does anyone have any suggestions on how I could get or make a hexahedral mesh of a helix?
I am currently using Comsol MultiPhysics 3.2b. The problem that arises in Comsol is that I have a helix with a thin cross section but the height of the helix is very large. So to get good resolution...
If time is not an issue, is there a way to get around the limits of winodws 4GB limit on virtual memory? I think there is. This link talks about increases virtual memory to 64GB.
Increasing virtual memory
However I did to do more research on the topic. What do all of you think?
I am working on a research project at Harvard. I have to measure the normal force created by a vine around a cylinder. It is interest problem posing many complications. See this video for a better understanding (requires divx and take a little while to load):
