Re: Autodesk Lawsuit - Non-Transferable Licenses

Hi Chris

Same old, same old...
Blaming software developers....
Now look what you have made me do...
Sake

Until you take responsibility for your own actions....

If the software is crap, dont use it. Tell the developers what you want; dont make them have to guess what you want. They will love you for it. Tell your engineering authority if you are a team player. Dont put up with it.

Between dysfunctional engineering institutions and piss-weak regulators, things are getting into a fine old state.

Just finished putting a new deck on my trailer. Increased the deck thickness which meant I had to relocate the headgate and tailgate upwards. This involved grinding out the hinge straps and re-welding to the gates. Forgot what a crap welder I am - call me Captain Birdshit (MMA). As a consulting mechanical engineer, I am occasionally asked about welding matters. Theoretically, I'm sound but practically I'm random. So I can talk the talk but cant walk the walk, and it bugs me seriously.

Tomorrow, I will be trying to revive my 1968 Honda CL50 street scrambler which I purchased to participate in a moped run near home in a months time in a misguided attempt to recapture something that never happened. I purchased it off the internet, gave it the obligatory post-urchase top-end looksee and it started first kick after probably 30 years hibernation. Wont start now, though, in spite of a healthy spark, a full floatbowl and clear jets. Oversight is the primary suspect.

A 450NB pipeline that I look after is about to have its operating pressure increased. Its flanges are currently rated for Table E (14 bar) but we will need a new rating closer to Table F (21 bar). I will probably accommodate the increased pressure by drilling out for larger bolts and possibly adding a backing flange. But I am unsure of the allowable deflection of the flange between bolts to prevent gasket blowout. By writing this question, I have realised that if I calculate the simply supported beam deflection between bolts of a table E flange at 14 bar, then by increasing the combined moment of inertia of the flange beam assembly by 21 over 14 and correcting for bolt spacing changes to limit deflection to the original value then I have overcome the primary design requirement and only have the secondaries (e.g. change in bolting pcd) to consider. So I no longer need to ask the question at this forum, but hopefully by tabling the above thought process, some members may realise that the solutions to many problems are within the abilities that they already possess.

More to follow...........

Cheers

Steve
