We always get excited here at Major Engineering Towers when engineering gets a specific mention. Listen to the whole thing, however at 13 minutes in there is some very interesting discussion on the link between the popularity of tinkering at home, and the shortage of good engineers.
When dealing with complex curves (such as aerofoils), one may see unexpected behaviour when trying to create a closed region. You insert an offset line perhaps (making two complex curves), close off the area with carefully positioned small lines, trim where necessary (normally a useful check in itself), and all seems well. Even when doing a “Select Chain” and checking the sketch relations, everything appears correct and present. Alas, the region cannot be used for an extrusion, loft, or any other similar feature operation, with SolidWorks insisting that the region is not closed. Get around the problem by closing the region with excessive overlapping lines, trim it back, and then it should work. Hope this helps somebody!
Always thoroughly enjoy the podcasts from The Infinite Monkey Cage, but particularly enjoyed the bias towards engineering in this one. I also couldn’t help but smile when the Eurofighter was mentioned, as I was working on its ejector seats components at that very moment.
I don’t mind admitting that I have never been hugely interested in this project. However, I think the arguments raised during the discussion are valid. Yes there are some useful technologies coming out of it – hybrid rocket engines for example. But if nothing else, this project has the potential to inspire the next generation of engineers. In my humble opinion, this in itself is worth far more than any new technology.
