Wow, this explains pretty much every single issue I have been having with bools for a while. I even got to the point where I just stopped using Exact because I thought it was broke. Can't thank you enough for this video.

[@UmNãoSer]

Same, thanks alot

[@jmh3d]

Every once in a while I'll see users post a boolean problem they are having and I just paste a link to this vid and say watch it. There is nothing else anyone needs to know besides this video to be confident in their boolean modeling. Much thanks!

[@near--zero]

dude I learned more from you in the first five minutes than in the last four videos about the same topic. THANK YOU~

[@backforblood3421]

Here's a checklist that will probably solve the problem for most people. Each step should be carried out on each object involved in the boolean operation after the objects are all rotated, scaled and positioned as intended for the application of the modifier: "Object Mode>Object>Apply>Rotation & Scale" or "Ctrl+A>Rotation & Scale" "Object Mode>Object>Set Origin>Origin to Geometry" "Edit Mode>Select>All" or "Edit Mode>A key on keyboard", "Mesh>Normals>Recalculate Outside" "Edit Mode>Select>All" or "Edit Mode>A key on keyboard", "Mesh>Clean Up>Delete Loose" "Edit Mode>Select>All" or "Edit Mode>A key on keyboard", "Mesh>Clean Up>Fill Holes"

[@dolphkawalec3527]

You are my hero, Chip. Been fighting with a job using multiple Boolean and Bevel modifiers. You solved every issue I had. Thanks sooooo much!

[@robinsquares]

Thank you so much! I've been treating the exact modifier as if it's basically broken.

[@RobKenning]

Face normals used to get me every time when I was learning Rhino. Brilliant vid on this subject.

[@dimpubora2088]

Oh my goodness, after 2 weeks of research, i found the solution. Thank you sir,

[@artekal3d]

Thank you so much for this! I was stuck on a thing for 1-2 days where i had to do engraving on a ring with text, i've done it several times before but this time i had to engrave chinese text and it wasn't producing the desired result! The very first tip about manifold tip really helped me figure the problem out and I already had a plugin to clean up the non manifolds! Thank you so much!

[@musikdoktor]

I was facing a problem with booleans and the problem was with the normals.. THANKS!! you've save me hours of time!

[@powersprouter]

hallelujah. the face orientation color adjustment is genius. now i understand Exact way better, thank you.

[@1963fram]

Thanks Chipp for the clarification! For those wondering, with Hard Ops, select an object with booleans then use the shortcut CTRL+SHIFT+b to get to the Hops Bevel/Boolean Helper - there you can set the Fast or Exact for all the booleans in your object in a single click.

[@dyshin123]

Thank you for the clear explanation! I suffered that issue like having a nightmare after i had modified a large .stl file. I know that might have issue in manifold, but after watching this video i decided to rework and make it better. I really appreciate this.

[@theDoomswitch]

Wow this was really amazing. You have a way of explaining things that is very simple, direct and easy to understand. Thank you!

[@CalmRelaxing.]

This video saved me omg ive been so confused with the boolean modifier, thankyou so much

[@rohteshmehta]

Absolutely AMAZING. Solved all of my problems with belnder.... thank you very much!

[@alexgram4345]

You are the MAN ! Thx a lot..... Thought is was too complicated for Blender to calculate! Had to give up 3D prints on the fly and complicated booleans too... Hours spend to try to solve it on my own - but hey..... Flip normals ;)

[@LostKitty64x]

super helpful video, my issues with bools were listed here, it's probably to do with normals plus the scale I'm working on my unit scale is 0.001 and i'm working in millimeters. I used bool modifiers on objects with a lot of strange and intersecting geometry, and it has been messing up my 3d slicer results to the point I won't even go ahead and print, holes everywhere, only on objects I did bool modifiers on..

[@happytimelogan]

I'm constantly flipping face orientation on and off, that tip alone is worth it's weight it gold, very yes chip, very yes.

[@memnok9980]

Proper scale saved me when doing exact union booleans. Almost walked away again. Thank you!

[@mixchief]

@ChippWalters This video is a pearl and an eye-opener. Thank you, thank you!!

[@Kharazm4th]

The best boolean tutorial and extremely useful.

[@PowerBiWithVivek]

We can use shift + ctrl + alt + Z to change from solid to wire, wire to bound

[@FilmSpook]

Many Thanks, my Friend!! You're Awesome, and I wish you your Best Year Yet. 🙏🏾

[@mastas7]

man i am so glad that i decided to make myself a coffee, sit down and take my time to watch this video! Thank you so much for explaining jesus christ i think all of my friends and collegues have no clue! ...this knowledge will stick with me for maybe the rest of my life hahaha

[@ChippWalters]

Glad you enjoyed it!

[@NoBrainerLanguages]

I admit I gave up exact boolean right off the bat. A procedure that gives maximum precision is crucial to me since I do some 3D printings of my own models.

[@Dainaccio]

This video is so dense of useful information 🤩 thank you very much!

[@garyrizzo7697]

Thanks for all of your hard work and shaing it with us !

[@infosham80]

Thanks from bottom of my heart. you help me bro. awesome

[@mubaraqohimeyi]

Bless you Chipp. this was a life saver

[@wickedinvi8466]

Amazing! just speachless so good explanantion.

[@kenw8875]

excellent content Chipp! another weapon is to install the native add-on [3D-Print Toolbox] in Blender. the Cleanup button...Make Manifold....is a one-step 'watertight' selector. btw, the Blender Bros (ryuu ponte, josh gambrell) highlighted that cool U/I setting....you discussed at e.t. 10min, for flipped normals where you only show Red for flipped normals and no color {grey} for proper normals.

[@wijoyosantoso759]

Thank you Chip, for the explanation

[@Pigjes]

Thanks, really helped perfectly!

[@OttrPopAnimations]

thank youu! you fixed my problem!

[@EHManjo]

Amazing- learned a lot! Thank you!!

[@sir_Mauser]

Great tips! Thank you, Chipp.

[@joonasmakinen4807]

Superb video! Inconsistent normals was my issue, thanks a lot! (I actually created special objects by from_pydata and didn’t realize that few polygon vertices were given in wrong order until now.) I had several months issue with the Boolean modifier, believing that it sucked, but actually my own work sucked instead. Thanks for giving credit to the author as well!

[@jmh3d]

Is it necessary to apply scale for boolean operations? It plays a huge role in other modifications to objects, so wondering if that's also a thing for booleans.

[@ChippWalters]

No, only in extreme scales.

[@SuperFreak117]

Thank you, flipped normals were killing me.

Synth is next on my list.

Super!

[@TheStrafendestroy]

Hello sir I'm trying to create a seam on a model i want to make for my fiancé to hide during assembly. When I use bool tool it says disabled and when trying to select the object with the eye drop it wont select the small plane i made and when i used the eye dropper on the model for some reason it only highlights the torso,neck,leg,arms, and leaves out the hands feet and head

Is there a way to make Boolean with a small gap?

[@ChippWalters]

See the booltools extension and the slice function.

[@ritzyfritzy5318]

Help me, I converted text to mesh, and when I boolean it, only half the text actually works, the other random letters just fuse to the block. I cant figure it out!

It works actually opposite for me-if the mesh is in red color, then the exact Boolean works, strange :)

No idea.

9:00 Ran into this one!

[@visualworx]

I surprised that many people don’t know about this…

[@wildmangeorgesrcchannel6916]

boolean is garbage in blender. i got an object perfectly manifold its just a beveled box the size of a iphone and it cant cut it. no matter what. followed the entire video and still no dice

[@ChippWalters]

Post it on my Discord and I'll take a look and perhaps identify what the issue is.

[@alexgram4345]

But that is not normal ? Why Blender flip normals on a copy, and what is normals ? :) Not an entirely rookie, just don´t get the fact!

[@ChippWalters]

You probably need to read up on normals.

[@alexgram4345]

@@ChippWalters I probably should ;) But now all my 3D prints works like a charm - thx again.

[@despiertateymotivate]

noup...I honestly hate when people don't explain every single command they type or at least show the command helper available on Blender...not useful at all since you went rushing on this video...

[@ChippWalters]

No, not rushing on this video, exactly the opposite. I typically have over 300 edits in a 10 minute video. This allows me to go quicker so that people who are following don't have to waste time. If you want to go slower, then just pause and review the video at your own speed. That said, when you edit a video that much the screen control commands get edited out and confusion ensues.

[@zanderalberto3576]

Every time I try to use exact booleans, the part im trying to apply it to just straight up disappears

[@ChippWalters]

Probably flipped faces
