    Adding manufacturer's rep relationships to consulting business

    I'm a consultant. My expertise is in precision machine design and optics. I primarily serve the semiconductor and aerospace/defense industries, although I've found increasing interest for the same but involving extreme conditions such as refractory furnaces. My projects typically involve new...

    Keyboard shortcuts for principal views

    The following thread explains how to set up keyboard shortcuts: http://www.eng-tips.com/viewthread.cfm?qid=220591&page=5 The original poster wanted to set up Ctrl+1 through Ctrl+7 to toggle between model views, like in SolidWorks. Coming from SolidWorks, I wanted to do the same, but there was...

    TeamCenter & NX: Recover earlier version of a revision

    We use NX 7.5 with TeamCenter 8. Our system is set up to maintain a rolling backup of the last three saves of the current revision. The assembly I'm working on has become corrupted, so I'd like to recover the previous save of the current revision. My understanding is that this is done in...

    Constraints failing - is this an NX 7 problem?

    This is infuriating. I constantly have constraints - usually between datum features, sometimes between geometric features - go bad. The latest case is a simple assembly: 1 - Top Level Assembly 2 -- Coordinate system created in assembly 2 -- Component inserted into the assembly 3 --- Coordinate...

    Using PSE like Parts&Vendors

    I'm relatively new with a company that has used I-DEAS with TeamCenter for years & has recently switched to NX. Like at many companies, I presume, TeamCenter is used as little more than a PDM system: check in, check out, a little bit of workflow. I'd like to use TeamCenter similar to how I've...

    Importing a STEP file FROM TeamCenter into an NX part

    I frequently receive 3rd party data, such as optical designs as STEP files, that I would like to control in TeamCenter. I would then like to create native NX part by importing that STEP file FROM TeamCenter. But I can't figure out how to do that. When I select FILE->IMPORT->STEP203..., however...

    Constraints between datums are way out of scale

    I use a lot of Touch Align constraints between datums of different parts, especially early in development & for optical components. Unfortunately, the resulting symbols that are displayed are often way out of scale and seem to point to random places in space. It makes it difficult to work with...

    Any way to make datums more easily selectable

    Even with the datum filter on, I find it difficult and sometimes impossible to select the specific plane of a coordinate system that I want. I need to orient the part so that that the csys "opens" toward me, because I can't pick a "far" plane "through" a near plane. Even when the csys is...

    Creating simplified & detailed versions of a part

    I've used SolidWorks for ten years but recently started working for a company that uses NX. The company itself has just switched from I-DEAS to NX, with everyone (including myself) going through a week of training. So we are all starting at about the same level of expertise. I would like to...

    Heat transfer for forced convection on a plate (NOT across a plate)

    I'm looking for relevant calculations for forced convection on the face of a finite plate. There is plenty of information about forced convection across a plate, like a PCB cooled by a fan. Definitely not what I'm looking for. The application is a vehicle-mounted optical window to be heated...

    Equivalence of XY and compound true position tolerances

    The hole-to-edge toelrance in an XY tolerancing scheme is roughly equivalent to the pattern locating (1st) part of a compound true position tolerance. And the hole-to-hole tolerance is roughly equivalent to the pattern (2nd) part of a compound true position tolerance. Assume the hole-to-hole...

    Did it take 8-12 weeks to learn your PE results?

    The PE exam materials say it will take 8-12 weeks to get your results. I'm hoping that that's a conservative estimate. If you've taken it, what's been your experience? Thanks, Rob Rob Campbell www.livejournal.com/users/robcampbell

    Publishing articles in trade magazines

    I've read that this is one of the best ways to promote your business, whether it is consulting or providing a finished product. I notice the byline when I read an article in Machine Design. Has anyone had success with this? Care to share your experiences? Thanks, Rob Rob Campbell...

    "Reference amnesty" for engineers in industry seeking PE licensure

    A lot is written about whether the industrial exemption from PE licensure in the US is a good thing. Regardless of whether licensure should be required, the requirement that applicants in industry have three references from PEs to sit for the exam makes it difficult even if they wish to. PE...

    Transforming thin sections to analyze with solid meshes

    Time didn't permit me to solve my last problem of extracting reaction forces from a shell model to use as an input in the solid analysis of the mating part. I will revisit it, so I know how the next time. I'm still accepting advice, however. While discussing a similar thin section/fat section...

    Extracting reaction forces from a shell model

    I am analyzing a thin-walled bellows that is welded to a thick ring; they are of different materials. The loading is due to the differential thermal expansion between the two. Because of its thin section, the bellows must (and should) be modeled as shell elements. I'm using CosmosWorks 2004...
