I want to know if there's a quick and easy way to copy and paste faces or geo in general like I could in modo. I literally would press control C, Control v and paste or copy to my hearts content quickly. Is that possible in blender?
Hi im new to Blender and i want to know when im in edit mode if i can copy or cut a selections of polygons faces and paste to another mesh.  Thanks in advance for any help
So, when I point a laser at a piece of wire (pointed at a specific angle), a circle of light appears on a wall behind it (see image below). I am trying to see why this happens and if there are any readings on this. Could anyone give some tips on what I should search for or any references?   ()  So this is a problem for a physics tournament, but I haven't tried it myself yet. However I have found a video depicting what I mean. How can I show that $n^2&lt;n!$ for all $n\geq 4$ Step 1 For $n=1$, the LHS=$4^2=16$ and RHS=$4!=24$. So LHS$&lt;$ RHS. Step 2 Suppose the result be true for $n=k$  i.e., $k^2&lt;k!$ Step 3 For $n=k+1$ $(k+1)^2=k^2+2k+1$ What will be the next step? What is the most portable method of launching a terminal emulator? Is it possible to use a MacBook Pro as a second monitor for my iMac? Both of them have a Thunderbolt port.  If not, is there any other way? I know to secure safety it is now not allowed anymore to open apps that were not downloaded from the mac app store.  But surely there is a workaround for this to open an app that you know is 'good' but just isn't in the app store. Preferably allowing only that app and not allowing all downloaded apps to be opened.    How do I open an app that is not downloaded from the app store in mountain lion? Is there any way you could revive Guest Sessions in a future LTS distro?  Guest sessions are good security - they give me just enough power to do what I need to do on a daily basis without risking my system. In short, Guest sessions save me from myself.  I had upgraded from 16.04 to 18.04, gotten a problem I couldn't fix and was all to happy to wipe and rebuild my hard drive and return to 16.04.  I can't be the only one who feels this way. blink code(escape code) has been removed? According to the Third Newton's law of motion:        For every action there is an equal and opposite reaction.   So, I understand that if I hit a brick wall with $50\, \mathrm{lbs}$ of force, the brick wall also hits me with $50\, \mathrm{lbs}$ of force (usually painfully). In this instance, Newton's third law makes sense. What I'm confused about is, if I hit a patch of drywall with $50\, \mathrm{lbs}$ of force, it's probably going to break, and due to the lack of pain in my hand, I can tell it did not hit me back with $50\, \mathrm{lbs}$ of force.   How does Newton's third law apply to situations when one object or the other is destroyed? It certainly seems like at that point it is incapable of delivering the full force of my blow back to me. What happens with the energy? Given a DateTime object, how do I get an ISO 8601 date in string format? Given:  DateTime.UtcNow   How do I get a string which represents the same value in an -compliant format?  Note that ISO 8601 defines a number of similar formats. The specific format I am looking for is:  yyyy-MM-ddTHH:mm:ssZ keep duplicates out of $PATH on source I have the following code that's source-d by my .shellrc  PATH="${PATH}:${HOME}/perl5/bin" PATH="${PATH}:${HOME}/.bin" export PATH   but if I make changes to other code and then source this file, my path continues to get longer and longer with each source, each time appending these when they're already there. What can I do to prevent this? How to recenter an object's origin? So, I'm working creating a lamp... yes, newbie here.  After modeling for a bit, I noticed that my point of origin was no longer the center of my object:    How to I reset an object origin point to the center of it's geometry? I'm trying to print types like off_t and size_t.  What is the correct placeholder for printf() that is portable?  Or is there a completely different way to print those variables? How to import footage in the VSE for optimal playback and organization? How to import footage in VSE for optimal playback and organization, using proxies and workarounds? I would like to restore LightDM to its default state, because for some reason /etc/lightdm/unity-greeter.conf is now an empty file.  Deleting /etc/lightdm/unity-greeter.conf and then running sudo apt-get install --reinstall unity-greeter doesn't create a new config file as you might expect.   How can I restore a missing config file? What exactly goes into a transformer's VA rating? At a fundamental level it seems that there has to be a limit to what the VA rating can represent.  For example if I draw 2 Amps-RMS from the secondary of a 30VA rated transformer at 15 Vrms this makes sense as the maximum Complex Power I can draw. Still, at a power factor of 1 my maximum current in the transformer would be sqrt(2) * 2 Amps.   But what if my power factor is abysmally low (ie in a DC rectifier) due to harmonic distortion and while I still draw 2A-RMS I have brief current spikes of 15 Amps? Surely the transformer's magnetics couldn't handle these spikes as I'd expect the core would saturate.  My question is what is the practical limit for VA ratings of transformers? Would brief current spikes that reduce to only 2A-RMS in this case be fine? Obviously the secondary/primary copper losses play a part in the rating but how do the magnetics factor in?  I ask this because I am designing a simple bench power supply using a 125VA transformer with a 24Vrms secondary and am trying to figure out how much power I can draw before the current spikes into the inductor are too much for the transformer. I also don't want to have to resort to active PFC as I don't want to risk messing up any HVAC PCB design.  Thank you How can I produce a 'ring (or wheel) chart' like that on page 88 of the PGF manual? Commutator subgroup and cyclic normal subgroup Every planar graph has a vertex of degree at most 5. I am trying to prove the following statement, any help!?     Prove that every planar graph has a vertex of degree at most 5. Values of $\sum_{n=0}^\infty x^n$ and $\sum_{n=0}^N x^n$ Why does the following hold:  \begin{equation*} \displaystyle \sum\limits_{n=0}^{\infty} 0.7^n=\frac{1}{1-0.7} = 10/3\quad ? \end{equation*}  Can we generalize the above to      $\displaystyle \sum_{n=0}^{\infty} x^n = \frac{1}{1-x}$ ?   Are there some values of $x$ for which the above formula is invalid?  What about if we take only a finite number of terms? Is there a simpler formula?     $\displaystyle \sum_{n=0}^{N} x^n$   Is there a name for such a sequence?    This is being repurposed in an effort to cut down on duplicates, see here: Coping with  duplicate questions.  and here: . What are good strategies for booster drafts? I know that doing a booster draft can be somewhat complicated, because to really be good you need to know a lot about the set you're drafting (or be really good at evaluating cards quickly) and to pay attention to signal cards.    Besides going into the whole complicated strategies of knowing the set and paying attention to signal cards, what are some relatively simple/basic guidelines for drafting?
