I want to create a custom axis for a bone to rotate around, which won't be along any one of the axis X, Y or Z. I want to use it for a concept car which uses some body panels to use it as an active air brake. So they'll be operated in an angled way.  Can anyone help...
I've been modeling an F-15, but when I rotate the flaps on Y-Axis the Flaps offset from the wing and they look like they are about to fall out, so I end up correcting it by rotating in the X and Z-axis to align them correctly.  However when I rotate them back from the Y-Axis they look distorted again because I did rotations on the X and Z axis. I tried riding it, no help. I saw something about custom orientation to fix it but that was not clearly explained and it was done on an ideal plane that was (0,0,0); mine is pre-rotated on all axis.   I'll take scripts if needed and I'm using Blender 2.8.  When I rotate it on the Y-Axis:    Fixing it using X and Z rotation:    Rotating it back on the Y distorted it again:    Here's the wing with ailerons and flaps:
Require reason for post deletion and un-deletion? Could we have a method of explaining why we think a question or answer should be deleted?  It could work identically to closing a question, maybe with an additional text-input box (like the "Requires Moderator attention" flag option) to provide additional info because the reasons for deletion should really be more specific..  For example, "exact duplicate" doesn't explain to me the user has re-posted the same question, thus, it should definitely be deleted (not just left closed). Like with close-messages, these reasons would be listed under the deleted item (or answer).   I don't think comments are suitable, as they can be a pain to quickly.. "extract" deletion reasons from them - I have to scan through the comments, and they may all be irrelevant.  Equally, for un-deletion, it'd be useful to know why another user thinks a question should be restored. For example "new user deleted the question after they accepted an answer", or "Jeff went insane and started deleting any questions with the letter O in it".  I think requiring un-deletion reasons is possibly more important, since commenting is disabled on deleted questions - we have no way of explaining why we think it should be restored Union of a finite set and a countably infinite set is countably infinite I'm referring to the colored circles with numbers next to them on the top of the page, to the right of my reputation counter. What do they represent? I know it has been discussed that it is not possible to start an application from an usb drive upon connection due to limitations of autorun (or autoplay??) in Win 7. But it is possible to create a scheduled task having an event type trigger. Surely there must be an event occurring when the drive -- or any USB device, for that matter -- is connected.    Does anybody have the slightest idea which Event ID should I use? Or at least what type of event? Where can I find the event in event viewer? What is covered by CDIC savings deposit insurance?

My professor announced the grades. He told us in each part what grades we had. My oral presentation for the project was way better than other students. But he just gave me 89 for oral and gave others 88.  I think it is not fair at all, because most of the students were not clear or the did not consider timing. He also told me that "your presentation was very good".  Also, I performed very well on the final exam but he also did not give me the 100. I think it is not fair.  How can I make a complaint?

Counter with 4 flip flops jk synchronous from 3 to 13! I have to create a counter with 4 flip flops jk synchronous. The counter shall count in this order: 3 to 13 and then to 3 to 13 and so on..  I have to use logisim simulator.   Ok. So i think its solved. I realized that the circuit needs to start at 0 ou 1 and stabilize after the 13 and then it goes to 3. Thanks for your help.  Hope this will help for somebody else too.  Thank you all for your help! Anyone seen this one yet? Vote too old to be changed, unless post is edited My vote was only a few hours old.

See also: How do you distinguish between magic effects that bypass immunity and those that don't? This question was triggered by .  Basically, it goes like this: If you have a weapon with a certain magical effect, let's say the minor property unbreakable (can not be broken, requires special means) or temperate (no harm in temperatures between -20 to 120 F), it can bypass the immunity of something like a Werewolf because it is magical instead of mundane. This goes for any minor property because those properties are under the Magic Items portion of the DMG on pg.143.  How does this differ from a pair of gauntlets with the exact same effect being used as an improvised weapon (emphasis added for clarity) from dealing damage in the same manner to the same Werewolf? Or something that's clearly not a weapon like a Shield of Missile Snaring being used to bash an opponent? How to identify the process locking a file? Hypothetically, should I pay off the smaller + higher interest rate loan first, or the larger + higher absolute interest cost? I have this hypothetical situation on my mind and I am not sure which is the best solution. Given:  Loan 1: $340,000 at an interest rate of 1.69% per year Loan 2: $40,000 at an interest rate of  3.6% per year  I have a fixed amount available to pay these, let's say, $1,500 monthly and I can decide how much I want to pay each one (I could pay 750/750, 1000/500, 1500/0 for instance). I do not have a time limit to pay these. My question: What is the optimal way to pay these? What I always heard is: pay the debt that has the highest interest first. This would lead me to a solution: pay loan 2 as fast as possible. But the total amount of interest on 340,000 is higher (in this case, $5780 annually) than the amount over $40,000 (1440, in this case), so, to me, it feels I should pay the Loan 1 first. I would love to run some simulations, but I have no idea how to calculate these things (I don't even have a clue on how to research it). ps: this is really a hypothetical situation, I am not getting such loans without being able to calculate it, don't worry ;)
