- Blender 2.8 how to split a mesh into two parts using the bisect tool. This video will use the bisect tool to cut a mesh into two sections and then use separate by selection to break one piece off.
This method works in Blender earlier versions too.
Most people would’ve made this 15 to 20 minutes, you made it 4 minutes, thanks for this quick straight to the point quality tutorial!
I have literally been looking through long winded multi step videos trying to find a simpler way to bisect for an hour, this simplifies it greatly tyvm for the post!
2 years late but you helped me solve another problem I had which was the origin being in a completely different place to the object
Thank you. Was exactly what I was looking for and you went strait to the point. I used this to cut a pelican into smaller pieces so I can fit it onto my 3D printer.
You are gold! Thank you so much for this tutorial! It is so vital to modify mesh only by slicing in parts!
Breaking up is hard to do, unless, of course, you watch this very informative video.
THANK YOU! THIS IS THE FIRST ACTUAL TUTORIAL I ACTUALLY UNDERSTAND! Thank you so much
This is super helpful for mixing meshes with parametric models. Thank you!
a+ Tutorial! Crisp, no blabla (german for "useless add-on Information"), easy to adopt. You should do more of those!
The bisect tool isn't tucked in my knife tool, as far as I can see. Clicking on the knife just gives me the knife option 😰
Edit:
Just found it- you have to press and hold the knife icon
all you have to do is hold click
Thank you!
thanks so much yo
Pro trick: watch series at flixzone. Been using it for watching all kinds of movies during the lockdown.
@Rene Dominic definitely, I've been watching on flixzone} for since november myself :)
Kept getting stuck on either the bisect tool not working due to an error about not having selected faces/vertices, or when it did bisect, it only had selected half the model. Ended up fixing it by going select>select all, which let it cut through. Big props for giving a pretty straightforward video bro, even if 3.5 kinda janked it up a lil, haha.
Thanksss. Seeing tutorials like this are way better than reading forumns and trying to figure out screenshots and text instructions. This seems simple but i was not able to do it lmao UNTIL NOW
Stop right here and watch this if you are looking for a simple method to slice objects into parts. No intro. No merchandise sales. Clear, concise and straight to the point. Thanks for making the video! I really appreciate when it was over, I didn't have some god awful royalty free keyboard shit song looping in my mind. Usually it takes a good dose of Stevie Ray Vaughan to rinse that shit out.
Funny
Excellent tutorial - thanks for sharing!
I love you dude. My brain was explosing. Thanks so much
Perfect! This is going to save my hide. Super appreciate this tip.
Excellent video! Thanks for the info
clear and concise. THanks a lot
thank you so much for this great tutorial! :D
Wonderful and fast tutorial, thank you so much 🌹🏎
Did you make all this knowledge available for free? What person! You rock!
the last tip was a saviorrrr TY ! :D
ty dude. this is definitely what i need!
Very helpful video, appreciated.
Valuable tutorial, thanks Sir!
Thank you! This helps a lot!
Thank you, I’ve been struggling with this for a while. You’ve made it perfectly clear.
old video but the best and simple one for Bisect into two Parts👍
man thank you very much that helped to cut my topo to contours
This was helpful ty!
Simple and Useful Video
Excellent, love it.
Thanks for this you helped me out.
Very nice. Thank you
Good tut, dude. Thanks...
thank you. very useful.
Thanks for this!
This is a great tutorial! Thank you for describing the process for these types of straight cuts in such a clear and succinct manner! I do have an additional question, though: Is it possible to perform cuts like this using the knife tool along curved paths? I ask since I am conducting some work on surface scans of fossil skulls and I would like to separate the my models roughly along specific sutures, many of which have curved or sinuous paths. Any advice would be appreciated!
Thx you ahhhh this helped me so much
thancc epic tutorial helped me a lot
holy hell THANK YOU!!
im watching a speed run tutorial to create a street lamp and its hard keeping up with his steps. lol
Thx for the tutorial
THANKYOU!!!
I was missing the "select inner ..." and I knew that it needed to be separated but couldn't figure out how for the life of me.
*edit - also, I WISH Blender would just COMBINE the LOOPCUT and BISECT tools - life would be MUCH easier if one didn't have to go through ALL OF THESE STEPS in order to just cut AND separate a mesh ffs.
Perfect tutorial thank you for that explanation! Maybe I missed it in the video but is there any way to have the bisect tool default to leave clear outer and fill checked? Just trying to speed up the stylized rock modeling workflow ;)
Or...if your mesh is particularly bended inside (like a cosmonaut helmet for example) and the fill requires a little vertex cleaning first, you have to go manually and then use the "make manfold" from the 3D Print official Blender plugin module. That module complete your settings if you are into 3D print. However, great tutorial!
This tutorial was very helpful, its just when i go to click to cut the mesh the mesh subdivided right when i clicked the bisect thing
Thank you so much
Amazing tutorial, thank you so much I was struggling trying to find a way to do it by myself during a whole week
But how do you fill the both parts ? 😅😅
Amazing
thank you very much
Thanks for the very concise tutorial! But is there a way to bisect with specific measurements ?
thank you
Excellent thank you for making these videos, love it, helps people a lot.🥇🏆🚀🚀🚀🚀👍👍👍👍😁😁😁😁🎮🎮🎮🎮🌈
Nice Tutorial :)
Man, you've helped me like 4 times by now, I gotta say thanks!! +1 Sub +1 Like
So good!
Thanks
Awesome! How do I make a perfectly flat/level cut? Object is too big to fit on printer, I want to make a level cut to the x/y plane then add a cube insert and a cube hole so they fit together after printing.
Thanks!
is´nt there a way to fill and save both of the parts? when you did the bisect, one of the parts just dissapairs. i want to separate a part but i want to save both of them and have them both filled. i guess i can make a manually fill as you explained earlier in the video, but it feels like the funktion sould be there somewhere
Thank you.
Is it just for me or this in fact is the most stepped slice tool of all cad tools in the world?
is there a way to separate an item into more than just two parts? once its split in two bisect seems to stop working.
Can you slice on a plane? Like XZ or YX? I want to cut a symmetrical object that I sculpted to be non symmetrical down the original extruded vertices.
thanks :D
How do I fill both sides after the bisect. I can only get one filled. Thanks.
These blender tutorials are super helpful, thanks, but out of curiosity, are you ever going to make some more gamemaker studio tutorials?
Probably later this year I'll make a few. If you have a good topic feel free to suggest.
Thanks.
Thx moxy
one question. can i cut perfectly horizontal? i don't cann get tool to work on perfectly one axis.
thanks
your mouse sound very satisfying
If I had a dollar for every mouse click...
I found a better way of separating objects in two. It's not as intuitive but much more cleaner, and faster in the long run.
Create 2 boxes that touch on one face. Use that face as a separation plane. Move the boxes to a desired location. Now duplicate the mesh to bi cut in half. Use boolean modifier on one mesh and left box, and other mesh on the right box. Use difference, and boom. Super clean cut automatically filled in. While doing so with Bisect tool, I found out it's not clean at all. Often little triangles remain and edges are quite rough. Also if you wan't to use bisect and fill both sides automatically it's impossible. And punching in accurate coordinates every time is a bit booring. With boxes just grab and move them along axes or rotate along axes for quick adjustments.
Do you ever find that the boolean modifier fails on certain meshes (especially non manifold)? I know the bool tool add on works better. Also, instead of two boxes, would just one box used twice (once for difference and once for intersect) result in same, or not?
Or subtract one really really thin box. With one axis scale at 0.00001 it looks like a plane but it is still a box. It remove a slice so thin that it's invisible and we get two parts.
I think we can use the 3D print add-on to make the object manifold.
thanks for the long add
I feel like in some world a UI would be built to combine these steps. In the context of an object, I think the word "bisect" implies all of the steps shown here combined. Except in Blender the commands are spread out. If someone wanted the results output by the current "bisect" command, then maybe use another word for it, because this isn't "bisecting", it's the first step for bisecting.
is there also a way to do curved cuts?
btw good vid!
super
tysm
So I'm trying to do this to a car and I'm on Blender 2.9, Whenever I do the cut it will only cut out slivers and not the full half of the car, can you help me with this please?
I have a quick question, How do i undo my knife tool i want to turn it back to bisect
Thanks, is there a command that enables me to create a clean cut as when I import my cut halves into Cura for 3d printing the cut edge looks a little messy like the cut is not clean?
Thanks again.
You could try the Bool Tool plugin that does cuts too by using a cube and the Difference option
How do you get both shapes filled when bisecting? When I click fill it only fills the one selected
I know this is late but you could select all the vertices near the cut and then press F in the shape that needs to be filled. So if like you cut a sphere and one half is not filled just select the vertices near the cut in the empty one and then click F and it should get filled. Not sure if this is what you wanted or not.
Or if you look again starting at 2:46, you choose click on the bisect menu after you made the cut then check on fill.
@@mohamedelkayal8871 i have a model with more than thousand of vertices, i can’t find a way to fill both parts
@@dlpuppy7810 I think I did the cut, then save the outer filled part, then undo, keep the inner filled part with the same cut and save
I guess this is easier with a plan used for cut, easier that what I did (note the bissect attribute to made the same cut the second time)
Very useful video, thank you. And how to assembly two pieces?
You can J join two selected meshes.
is there a way to animate this? great video!
What is the key to have the submenu at knife ??
How would I cut it without it going all the way through the model/mesh. I was wondering ‘cause I am trying to make an arm come off a rig.
Dont use bisect tool. Use knife project instead and check the box to not go through entire mesh.
How do i get the rest of the tools I only have a few?
Great tutorial, I left blender for 3 years and they dont know how to act LMAOO
😂😂
My Bisect tool does not work is there a short cut for this because I am using laptop.
i have a car model that got from a website and i'm trying to separate the parts of the car(doors, bumper fender panels etc..) and add texture onto them. I'm doing it to see what the car would like after getting it wrap with the design i did. The person who made it, made the entire center of the car in one piece (fender, door, skirt, quarter panel. so when i try to add the textures it comes up like messed up and i can't get it to fit. so i'm trying to do it piece by piece but i can't get to separate the door from the main thing. When i try your way, it says " Selected edges/faces required
" idek what it means but i can't seem to find another way to separate them but your way, can you help me out ?
You separate parts of mesh by selecting the faces then press P to separate by selected. The new object created will still have origin at original car origin.
BUT you do not have to separate to put texture part by part. See my video on using UV Maps and Textures. You can just assign the texture to faces that are selected and adjust the UV Map to make it map out correctly.
0:32 how to tuck inside the knife tool? I spend hours and can't find a tutorial about how to tuck inside, help
What if i wanna cut along the edges. Say spit a cube in two diagonaly.
Yea, same question as Erby Walls, how do I bisect, fill and keep both of the pieces?
If you find out, post
When I bisect it adds a line around the object but when i do the select inner loop it only selects a couple of nereby faces but not half the object like yours.
sameeeeee did u find how to do??
Look in the bottom left there should be a box that says select greater or something similar click that.
@@WickedInsomnia I need more clarification.
When I click knife the menu does not show. How do I select bisect?
I want to cut something in half exactly at the Center so I have two equal halfs. I can’t figure out how to snap my curser to the grid so I can’t get the put the bisect tool at center. Can somebody please help me?
it doenst work.. it just takes a slice out but both sections left and right of the cut are still one moving piece together?
So happy i accidentally found this
As some have pointed out, depending on your mesh it might leave dirty mesh behind at edges. If this is a problem for your model, look at doing this with the boolean modifiers or the boolean tool plugin.
can you do this with planes? I've been trying to cut a video in half
How to cut the front part only?
Can you please help me? I have a bird model and successfully separated the left wing. I want to do the same thing to the righ]t wing, but every time I'm about to click with the bisect tool it gives me the error: selected edges/faces required. Please help I'm completely new to this.
Only thing i can think of: are you accidentally selecting the separated wing mesh instead of the body mesh? They share the same origin unless you re-center it and it might look like you have the body but you have the wing. Just a longshot.
I dont even have that many tools in the open edit mode. All that appears is "shear" How do I fix
