    Mass Check-in in TeamCenter?

    Greetings! I am working with an assembly with quite a few parts. I notice that sometimes the parts do not get checked back in when I am done working with them. Consequently, when someone else tries to work with the assembly, they get a read-only warning. The only way to remedy this is to go...

    Unknown update? (!)

    I am working in an assembly with a ton of parts and a few subassemblies. I have an indication that there is a part or parts that are out of date and need to be updated. I go to update the session, and NX grinds away, updating what seems like every part under the sun. When it is done, I STILL...

    Material properties causing problems in UG?

    I have recently run into some memory error (violations) in NX3 that I have been able to trace back to some material properties I have assigned to parts. In digging through the file, I found that NX3 is loosing some of the materials from the library, and basically corrupts the entire part. Has...

    Order of Export?

    Greetings! I am trying to export a bunch of solids to a parasolid file which will be read into an FEA package. The guy doing the FEA work said that he would appreciate knowing the sequence up front so he can create a meshing routine based on the internal ordering of the solids. In short, he...

    Internal error: Memory Access?

    Greetings! I have recently started running into a problem opening parts from TeamCenter. I click on a part in TeamCenter, and while opening the part in UG, I get a "ugraf" error reading: The following error occured whilst responding to an iteroperation request: Internal error: memory...

    Sport Pilot Rule?

    OK, here is an interesting question, that on the front, does not exactly relate to engineering, but dig a little, and it affects EVERYTHING we do! Is the sport pilot rule a good move by the FAA? I know there are a lot of pilots out there that love it because it puts them back in the seat...

    Human Modeler in NX 2.0.4

    Greetings! I am looking through the "What's new guide in NX 2.0.4" and noticed that the recent release has incorporated a "Human Modeler". Supposedly, the tool is located under: Modeling-> Tools-> Human Modeling-> Create Human However, I do not see this tool in my pull-down menu. Does...

    Missing edges in drafting?

    Hi all, I have been searching through the posts on this topic, and haven't found exactly what I am looking for. Here is my problem: I have multiple parts (an airplane) in an assembly, all of which are surfaces (sheets). I have brought the assembly into drafting, and I am looking at a side...

    Turning flow through rotor blades

    Greetings! As I am not much of a helicopter guy, I thought I'd turn to the helo forum for help. I am doing work on a vehicle with a rotor mounted at a 45 deg. angle relative to horizontal. I have a lifting surface less than one rotor diameter down stream of the rotor, and I need to...

    Interogating a part for color and transparency properties

    Greetings! I am starting to get familiar with Solid Edge. I client of mine sent me a part file, and the part shows up in a particular color, and is semi-transparent. I want to interogate the properties of the part, to find out exactly what color it is, and how much transparency is applied to...

    Global Hawk Flaps?

    Greetings, I am setting up an aerodynamic model of the Global Hawk UAV. I have looked extensively for the type of flaps used on the Global Hawk, but haven't found anything definitive. Is there anyone that knows the flap type on the Global Hawk UAV? Regards, Grant Aerospace Engineer

    Protecting equipment from lightning???

    Hello all! A guy I work with just read a book concerning computer hardware/software, and how to protect them from lightning. The author suggested that if you tie the cord in three knots (between the outlet and the computer) it will protect the computer from an electrical surge from lightning...

    Roncz Airfoil Data?

    Greetings! I am looking for information on Roncz airfoils. Any information at all. Does anyone have a good source for his airfoil coordinates, aero data, etc? It is hard to believe this guy has designed so many airfoils, and there is not an iota of technical information on the internet about...

    ADAMS Software for Aircraft Equations of Motion?

    Greetings, I am looking at the ADAMS software tools, primarily the "Solver" utility to come up with the dynamic response of a tiltwing aircraft. I have all the equations of motion writen out (we have done it all by hand already)but we need a package to look at the dynamic response as a...

    MSC.ADAMS for aircraft dynamic modeling

    Greetings! My company is faced with developing the math model for a new vehicle. We are looking at the MSC.ADAMS software for the dynamic respose calculations and simulation. We might also be interested in their aircraft modules for other projects. Has anyone out there used the ADAMS...

    Are the Extension Packs worth the money?

    Hello all, I have been tasked to looking into the MathCAD extension packs for our company. In the very near future, we will be involved with a consulting project that will require the use of multivariable diff. equations, and partial differential equations. These equations would all be linked...

    The 3-sided surface plague

    Hello all, I am again running into a problem I've been battling for a long time. I have 3 sides, and I need to create a surface between one edge, and 2 curves. I need to create a surface between them, but need the surface to be tangent to the edge curve. Could someone educate me on how to do...

    Aircraft Fastener Properties?

    Is there a specific reference for fastener properties and allowables? Primarily AN type steel bolts, and corresponding nuts, washers, etc. I am looking for Military specs for properties... I am looking through the ASSIST Online site, and am not having any luck with their primitive search...

    Reverting Back to a Previous Revision

    Hello all, I have run into a situation where I have a dozen parts all put together to form an assembly. On one part, I have created a "Revision B" with updated changes. Now, it has been determined that "Revision A" is "better" and we want to replace the new...

    Constraining a Spline

    I have imported a spline (an airfoil), and want to constrain the entire spline to a point. The problem arises when I try to constrain the starting point of the spline to a datum or line. The single defining point moves, but the rest of the spline stays put, and consequently my airfoil is...
