"just join these vertices" press J... " how on earth did i not know this until now ? lmao thanks
Haha we all feel silly once we learn something so obvious!
Don't worry my mind is blown as well lol!
J for Join, F for fill. P for part. Blender is logic!
I immediately ran Blender to test this shortcut key! O_O
Until today I used to K-nife them.
You're giving me the motivation to improve my blender abilities instead of playing video games all day during quarantine... I subbed
I'm so happy to hear that man! I feel the same; I can't enjoy video games anymore because there's so much to learn in Blender. I'm just working and learning every day. Shoot me a dm on Twitter (link in description) and I'll hook you up with my new hard-surface course for free so you can keep learning.
@@JoshGambrell Thank you so much! For some reason Twitter says that I can't DM you. My twitter name is TheBoomBoomKing if you wanna try to send me a DM instead
TheBoomBoomKing same! Im actually trying something in blender rather than just watching anime or playing games :D
@@chatter2765 ditto that!
OH GOD THE CASHES ARW MULTIPLYING
This is a day where hundreds of people have learned the power of J (me included)
The power of Josh? :D
I have learnt not only that, also a lot about what is "correct" or not regarding topology.
@@j.carlosmuro2435 No need to worry about what is correct or not so much, since there is not a "divinely true" or only one way to go about it. This is just a very good way to go about it.
Also, fun fact: in Edit Mode, "J" connects vertices together while also dividing faces. It's a way better form of editing already existing faces than deleting them then creating new edges or faces with "F", and it's an even faster "K" knife tool since we work directly with the vertices we want and nothing else, instead of worrying about foreground and bakground bleed and angles.
power of ctrl j too
This is why I like watching basic tutorial videos despite having used blender for years.
Every one I watch seems to teach me a new shortcut or feature of something I already use.
Thousands* :D
Thank you, I learned a nice set of shortcuts :) , the "J" , the "GG"
gg
GG is very useful... also try pressing 'E' afterwards to make the loop line up with the one next to it. You can then swap which side it will line up to with 'F'. You can cancel the operation again with 'E'.

@@bastoneliven8095 اهلا بك
Sorry, what's the actual key combination on 9:32?
All this time and I didn't know the J thing to bridge between 2 verts... Always resorted to knife tool.
Yeah J can be much quicker
Literally same. For as long as I've used Blender. I'm always learning new shortcuts.
I know J exists, but I still knife because I never remember about J when I have an use for it :/
@@tidiestflyer7570 Blender is Latin for OMG, I can't believe I never knew that shortcut!
CaptainFutureman lmao
Just a small note when creating faces: If you use Edge selection, you only need to click on two edges and press F, rather than having to select four vertices.
that will create overlapping edges
@@PixelBytesPixelArtist Why on earth would it do that?
@@PixelBytesPixelArtist what and no
BillRey he showed that exact feature in the video though ...
@@abaratien Yeah at 03:29
you can actually quickly dissolve verticies with Ctrl X instead of using the delete menu
Didn’t know that. Thanks!
I always just placed vertices on top of each other then merged by distance.
Vertices and Edges
ooohhhh thanks for the tip. I learned even more today.
Goddammit, blender is full of useful shortcut I didn't know
Pressing F repeatedly to fill in extra bits is the thing that makes this feel so easy, thanks for the tip
You don't even need to go to the hassle of adding a modifier.
Activate snap to surface.
Go to the magnet button above (shortcut shift+tab), change the ruler thingy on the side to face (shortcut ctrl+shift+tab) and check the "project individual elements" box.
Now align your view with your cylinder cutter, move and confirm.
All vertices will be projected to the other according to your view.
Don't even need to be a separate object if the "project to self" box is checked (current version is checked by default but older weren't).
I hope it helps.
Ps.: The "Snap to Vertex" is one of the greatest tools I use on hard surface modeling.
Someone mentioned this earlier and I didn't even realize there was a projection snap mode! That's super useful! Thanks for mentioning it. Had I known before this video I would've included it.
I tried but the circle stays tangent to the cylinder rather than wrapping around like when you use the shrinkwrap modifier. I have selected the "project individual element" box as you said. What am I doing wrong? I'm using Blender 2.82a. Also, where do I find the "project to self" box? Thanks.
@@davidesivolella5907 You probably did it in Object mode. You need to be in Edit mode though.
@@JoshGambrell You should also look up knife project. You can use an object to cut another and it ignores the cutter topology.
Create your cutter, select your object last, align your view, go into edit, on the upper menu click Mesh->Knife Project.
Works best in orthographic view.
You can check the "Cut through" to cut all faces, not just the visible ones. Checking the box will reset the cut, so if you don't want to align again, you can split the view and pan around in one while the other keep the "cut view".
I was going to recommend knife project, but this is so much better! I never had a use for surface snapping until this.
THANK YOU. I've been struggling with holes during my whole mesh modeling learning process. Coming from CAD, it's hell when you have to make holes in Blender. Pretty clear explanation, will try !
I always have issues with really messed up geometry and artifacts, I knew about the boolean modifier and used it but half the time it wouldn't actually delete anything it would essentially just cut the shape into the part and I would always end up with messy geometry that meant I couldn't subdivide it, but this is extremely useful and has made me a better Blender user. Thank you!
Finally getting away from 3DS Max that I've been using for over 15 years and learning how to perform the same techniques I used in Max is like a fresh breath of air, especially when also realizing that there are so many shortcuts in Blender that are time savers that would save hours of work.
I am just starting in anything 3D. Found out about the Amazingness that Blender is a few months back, & I've been hooked ever since. Your tutorials, I love the way you explain things & seem to KISS, if you know what that means. I dig it, makes it so much easier to learn this newfound love.
You can also use "bridge edge loops" to fill polygons around the hole (make middle loop cut for cylinder beforehand)
Thanks for this! Just got to say, I decided to properly learn Blender again a few weeks ago and I absolutely love it, the community is awesome and theres no shortage of great ideas to learn from. Thanks again.
Thank you!!! Thank you for telling us about the messed up normals, was having such a frustrating time trying to figure out why my circles looked like crap when I smoothed them out, just needed to fix the normals, oh so happy now!!
This saved about 2 weeks of learning curve in like 6 mins ! Thanks
I think your new stategy will help most when joining 2 weird shapes together, like an I beam on a cylinder or something. Circles on circles are easily done with booleans but this 'just extrude it inwards and then extrude the new faces out' technique only works when working with a perfect cube or circle. Scaling become a hell of an issue when applied to, for example, the letters G, Q, W etc... because their scaling will not be equal on all faces.
I am just starting to get more advanced with Blender but I was struggling with this very issue with my current project and I stumbled across this video looking for better ways than the boolean. Thank you this is just what I need
Hey Josh! Thank you so much for this video with several very useful hints around modeling in blender....Ctrl + Number adds automatically a subsurf modifier, edge select and F key create a new face, join two vertices on a subdived surface with the J key - incredible, I didn't know about this shortcuts before! Great job!
You can also cut in your mesh then select the edges of your hole and use the looptools Circle option.
hey josh. just so you know, when extruding or any similar type of operations, you can directly use the R/S/G shortcut to begin the desired operation without right clicking. so the shortcut combo would be E -> S (shift)X/Y/Z. a small thing but a really helpful tip to improve your workflow efficiency. there are other operations that are similar such as tear/rip. generally any operation that instantly edits the geometry (rather than applying after confirm. e.g loop cut and the knife tool do not instantly alter the mesh). keep in mind though that only one transform operation can be performed at a time like normal.
Please show us tear/rip.
@@AA-hg7xq google it yourself dude, these basic videos already exist, don't be a help vampire
Josh Gambrell Is there a video on this because I still do not get it.
I thank you for including the old Boolean method too. I'm a total blender n00b and I was attemtoing to cut an offset cylindrical recess into the surface of a sphere, and could not get your initial method to work, whereas the Boolean Method worked first time. Perhaps when I get more skilled at this I can give it another try. But thanks for this video! It was a big help.
Well done, thank you, Josh. Would love to see your take on architectural hard surface modeling (doors, walls ,roofs, etc)
Groboto is(was) a killer application for this kind of modeling with beautiful topology, basically parametric CAD modeler for mesh geometry... but unfortunately the developer stopped supporting it. Glad you are providing this valuable education for the community sir!
Thanks, man. Been using the second option for many years first in 3ds max, now - in Blender. Your way is much better. Sometimes I even opted to creating two separate objects not to cut holes in mesh. Now I won't have to do it. Thanks a lot.
Awesome man! Super glad I could help you. Always new things to learn every day!
I like the way you rotate the cylinder, it makes the original shape rotates in this angle so no need to apply rotation, keep the good work!
For flat sided objects, using the loop tools, circle function is also very quick, although it gives you some odd mesh patterns. So maybe only useful for certain applications. Top vid mate!
If you go to the add-ons preference, there's a a Loop tool where it automatically changes the loop cuts, lets say, a square into a circle. There are other shapes, but I use that to make a circle and then the subsurface modifier just makes it round.
Yes, this way is even faster
@@Elvera4art name please?
Name of add-on please 🙏
@@FnD4212 its literally in the comment, loop tools
@@ItsBittle Loop tools is default tools, but the add-on that make specific action like he describe is different. In add-on, it should be Loop Tool: "name of add-on".
Thanks dude, really useful. Just watched your hard surface modelling video before sleeping and I just woke up to find a new video of yours. Thanks!!
Awesome! Now you have a new skill set to add to the list
Great video. There are many different ways of achieving things in blender so it is refreshing to see side by side comparisons with explanation as to why one is more efficient than the other. Thank you 👍
This tip about fixing sides with "I" button was so helpful to me. Fixed like half of my work. Thank you so much!
3:48 Just a quick tip, in edge-select mode it only takes 2 clicks to select opposing edges to fill in a face, rather than 4 clicks on the vertices in vertex-select mode.
or Ctrl+RightMouse to lasso tool in one drag
Or alt click to select the border
Omg I was about to give up thanks!!!!
I actually didn't need to make a hole per se but this was still one of the best/useful tutorials I've done after making donuts and cars and random things for so long. Really love it when someone SAYS the shortcuts their doing quickly and what they do. I know I can read the screen cap of it but damn, I'm not Johnny 5 over here reading screens.
This tutorial has improved my consistency of the face between the fuselage and wing component. Thank you so much. Such as method can apply to extrude a complex shape from a surface. Such as the extrude the wing from aircraft fuselage.
Hi Josh, thank you so much for your video. I am new to blender and the 3D in general. 5 days in, but I am amazed what it can do and even what an amateur like me can do with Blender just after few days. Your video helped me a lot to discover some workflow and ways how to do things. Big thanks to you!
Awesome man! I’m so glad I could help you! I’m excited to have you as a part of the community :)
Josh Gambrell i thank you! Just did your “tutorial” 3 times with several variations. The basic is super easy, it becomes more complecAted when I start rotating the main cylinder or if I try to move the circle around the cylinder (it will start deforming). So if I was creating this for 3D printing I would need way more information how to make things 100% accurate. Thank you again. I will keep commenting on your tutorials as I will be going through them 👍
Dude, 27k views in just 2 days. Didn't I tell you channel is gonna blow up one day? Congrats. I love your content. In a day or two, after finishing my ongoing 3D Explainer video, I'm gonna purchase your Hard Surface Modelling Course on Udemy. But before buying it, wanted to ask, do you teach right topological modelling in it as well? Because that's what I am aiming for in my next videos.
Thanks man! I'm not sure why that one did so well but I'm guessing it's because it's valuable content the community needs :-)
Message me on Twitter @josh_gambrell and I'll hook you up with the course for free.
The course mostly covers boolean modeling and takes in topological considerations when adding booleans, but doesn't focus solely on mesh cleanup. Hope that makes sense!
@@JoshGambrell Thanks man. Messaged on twitter!
gotta say you really called something there. Still the best hard surface blender tutorials without contest (that I have found at least)
I had so many problems when using boolean operation but from now everything is so much easier and makes much more sense. I will restrinct booleans as much as possible so I have proper topology and no other issues at all.
I learnt about filling quickly, and joining verticies, on top of ways to make holes in objects. Awesome!
4:35 BlenderGuru gave a tip of noticing badly oriented normals.
In the viewport top-right (just left of the shading options) open up the overlays and there's "Face Orientation" under the category of Geometry. Blue is facing the camera and red is the opposite.
tahnk you
Nicely done Josh, keep bringing those cool and good tuts.
Thanks Richard, will do!
Wow, thank you from a Blender beginner. I learned so much from you in just 10 minutes! I going to try what I just learned and then I will watch more of your tutorials.
Both strategies are great, I was doing something that was basically a rectangle with a circle cut in the middle, didn't know about that Boolean cut, and the first strategy I'll use a lot, thanks!
"...And then just join these vertices here with the J key..."
Wait what?? Whaaaaaat???
You can do that??????????????
If you focus on these types of videos, not only will you help a lot of people on the construction, but I'm sure your channel will be very popular.
Found it easier to fill, if you do the central loop cut before (or do 3 loops from the start). Select two edges to fill, select one of the edges like you did and press F until everything is filled.
Great video, thank you, looking to get into Blender again!
Using the bridge command I think will correctly fill, between the large and small cylinder under most circumstances and is quicker than manually adding the geometry, for all quads topology you do have to make sure that there are the same number of vertices in the inner and outer edge loops.
I've always did it with boolean and then I cleaned clean all ngons
*sees comment section full of people talking about J*
Me: how did they not know the join function?
Josh: 7:56
Me: O.O
Best blender teacher ever, you explain it down to the root of cause. Great work man!
Thanks! This video has been extremely helpful. I have recently used this technique multiple times and it works great. Also, using the F key to create the faces has saved me heaps of time as well. I also use F to join verts, for some reason J doesn't work for me.
one other thing you can do here is use the loop tools addon that comes within blender (go ahead and activate that, it's great and has saved me a lot of time) and select the edge loops after you cut out the square (or rectangle) shape. Then you just have to right click to bring up the menu, and select loop tools > circle, and viola, you have your circle.
if "j" blew your mind, look at the F2 add-on (included in blender, just activate it)
remeshing is so good with this
Thanks for the advice. I’ll definitely be using this in my future projects.
The first way is how I always worked in modeling to create great topology. Then I was introduced to HardOps and Boxcutter which changed my view my first method a bit. Mainly when it comes to concepting and a non-destructive workflow. I found it's much easier to make client changes that way. I would love to hear your thoughts on both methods.
you should have done two booleans: One adding a cylinder as the extrusion, and another making the cut through both. Then bevel the edges. Would have been much quicker.
That "J" Shortcut... how.. HOW could I miss that :D
Thanks for doing this! Helped me out of a tricky bind.
I being looking for this for about 3 days.
I wasn't looking how to do a hole, but how to do a boolean.
haven't used blender in a loooong time, but thanks to you I found how to do it again
0:32 I like your instinct to do transformations in Edit mode rather than Object mode. ;)
6:27 Except translations. Those I normally do in Object mode.
I've had to apply scale one too many times hahaha
is it better to do it in edit mode?
@@pladselsker8340 It just saves some time because the rotation/scale is automatically applied when you transform in edit mode. In object mode, it changes and in the future you may have to apply it, meaning a small extra step is required. No biggie either way though :)
I'd just boolean it out and that's it, so both strategy is long :D Looks good though..
Thank you for this tutorial, super easy and explained really well!
What comes after perfection! This is trendsetting; Thank you very much for your time and sharing your know-how presented in a pleasant voice.
Watching a tutorial for something as simple as this makes me feel like blender was created by eve online players.
Yup. There's got to be an easier method.
7:25 this cracked me up ngl
Just tried the first way, it worked like magic ! Thank you 🙌
Thank u so much, interested in starting so soft during quarintine and just need a place to get started, thx for the support
Excuse me, "double-tap G?" Gonna start using that now.
Don't forget about "Alt S"
Intended tutorial: How to properly cut holes into surfaces
Actual tutorial: THE COLOSSAL MIGHT OF THE J KEY
In seriousness though, thanks for the tutorial, really helped!
My pleasure Xandru!
This video is old, but still really helpful! I'm trying to learn blender and seeing simple and short videos like this really do help a lot! Not only with modeling, but also with motivation!
Hey bro... Why did he cancel the extrude , in order to scale afterwards (like in 9:23)??? why do we have to do this before scale???
Great video. I was doing it this second way for sure. The way you created the polygons with the verts I didn't actually know it was possible in blender.
"just join-" WAIT WHAT
The fastest way is to get box cutter and mesh machine, bool it bool clean it and normal transfer
Well of course but I think it’s super important to understand alternative, vanilla methods as well so that way addons will be intuitive and truly improve your workflow.
I am a beginner and this helped so much! Thanks for all the useful shortcuts keys and tips. Well deserved sub and like
Very helpful video, thank you so much for including your hotkey history in the video!
I thought, this is another 2-minutes tutorial expanded to 10 mins. But for real, these 10 minutes worth it, because there is pretty deep review of the problem. But honestly, 1-2 minutes author has lost in very obvious and basic manipulations, like long intro, rotating cylinder or choosing view axis. Probably, people who think about clean topology, already know how to rotate cylinder.
Anyway, liked.
TH-camr: "Let me show you the most efficient way to cut a hole."
_[Proceeds to show the most inefficient way to create a circle loop and fill topology.]_
To speed up creating the same circle loop, do the following:
• Hit *[Shift]-[A]* then *[M]* for "Mesh", then choose *"Circle"* .
• Once the circle has been created, hit *[Tab]* to enter edit mode and hit *[F]* to make the circle a flat circle mesh without inner edges.
• Hit *[I]* TWICE to enter per-face inset, and change to desired width.
• Hit *[X]* then *[F]* to delete inner face, leaving polygon ring.
To speed up the filling of the gap between the circle and the surrounding rectangle, do the following:
• Hit *[Ctrl]-[R]* to add the center loop cut on the large cylnder.
• Select the outer loop of the circle by *[Alt]-clicking* on an edge, then add the selection of the inner loop of the rectangle by *[Shift]-[Alt]-clicking* on an edge.
• Hit *[Alt]-[F]* to fill the gap with an auto-triangulated mesh.
• Hit *[Alt]-[J]* (with "Max Shape Angle" set to 70°) to change triangle faces to quads.
You should also place the middle loop cut on the large cylinder before doing this operation.
That would have also allowed you to just keep hitting [F] until the gap was completely filled.
Hope this helps!
Oh my god! You saved my life there mate! This was one of the most frustrating things I've done when it comes to making some Minimalist room stuff, God bless ya!
Insanely helpful and articulate, thank you very much Mr. Gambrell
Everytime I see a tutorial with booleans, I cringe
Even though some experts recommend it, I just had too many bad experiences with it
It depends how you use it. Once you understand non-destructive boolean-bevel techniques, weighted normals, and topology considerations booleans can make you a much more efficient modeler.
@@JoshGambrell
Weighted normals modifier can really be good for a fast and good shading that stays after a subdivision modifier, but I would've like to have as many face strengths as I'd like instead of only 3.
What I end up doing is applying the modifier and then adjust manually.
For modeling, I already use "the correct method" that you showed in the video :)
But I don't blame beginners for using booleans, I learned myself modeling in Roblox Studio, where there is almost no mesh manipulation possible, except for booleans. (there isn't even an intersection feature)
When I look back at my old work, I'm proud, but when I toggle the wireframe mode, my eyes bleed...
Got to this video because last night. I made a very bad boolean
@@GUMMY_MKII Haha the beautiful outside but nasty inside that is the Wireframe mode...

Nothing but love for you man! I genuinely hope you can get out of whatever negative spot you’re in that influenced you to leave such a distasteful comment.
I looked on your channel and didn’t see that you’d uploaded any videos where you spent your own spare time explaining something in detail plus offering an alternative to give a balanced view?!? But you can spend time trolling someone who did 🤔 don’t bitch on other people’s tutorials, they take time and they aren’t as easy as they seem. Now fuck off you prick.

Thanks this was very helpful, I always hated how messy the Boolean version was. I also never knew you could double tap G to do a sort of Vertex Slide, I only knew about Edge slide which has its limitations.
Thank you! I was able to get a nice result. Great lesson.
Thanks so much for the explanation, this is very helpful.
This is a really smart method! I'm adding this to a playlist.
Thanks, Josh, for another great tutorial. Straight and to the point, just the way I like it.
Really nice, especially the 'fit & finish' tips. THANKS.
I'm starting a personal playlist for blender workflows, and this is the first video I'm putting in it. Thanks.
I'm gonna start using this method, thanks for this
That "shift+n" just honestly made my head explode. THIS is what I was searching for this whole time as someone new to blender. Holy.. I got so frustrated at weird sharp edges appearing especially when I created the neck for one of my first humanoid creations. Same for the bevels. Thanks so much man.
ooh thank you, I always had trouble with the boolean tool on round objects, but this is much nicer
This is exactly what I needed to know. Thank you so much!
This was incredibly helpful! I spent a good few hours trying to figure out how to create an eye hole for an awkwardly shaped object, and this worked perfectly
Hey bro... Why did he cancel the extrude , in order to scale afterwards (like in 9:23)??? why do we have to do this before scale????
Quite an important one for this workflow would be bridgeing, so you can just select the inner and outer "circle" verts and it will bridge them together perfectly
more like this would be good. RIGHT Short & sweet thank you Josh
I love this kind of small tidbit tutorial because it's most likely useful for any project.
Great work flow. I tried it with the LoopTools add on, worked a treat. Needed to make sure "flatten" was turned off in the settings and use insert instead of extract and scale :)
Excellent video Josh, thanks for sharing your knowledge
I'm about 6 months into learning Blender. Didn't know about the Shrinkwrap modifier! Thanks.
