On time as always. I’ve been having some boolean problems recently, thanks for the video

[@ArtisansofVaul]

I hope this helps out. Its quite a specific situation but its a good "cheat"

[@imonseii1436]

Another important thing to note is that the slicer does not care if objects overlap, if you have exported two models in one stl file. The slicer will happily slice two boxes that are overlapping, that have not been booleaned together. Realizing this has saved me so much time avoiding cleaning up models after wonky boolean operations. You do, however, have to make sure your individual objects do not have errors in them, such as inverted faces, or non manifold geometry.

[@imonseii1436]

also be aware that this usually adds geometry complexity to a model, so if you are exporting a high vertex model with lots of parts you haven't booleaned together, the file size will balloon in comparison to having booleaned the things together properly.

[@ArtisansofVaul]

While that is generally true it can cause a lot of issues. If the files have faces that are on top of each other the impact can lead to voids in the STL and issues with printing. If anyone is serious about providing files for other people (especially selling those files) I would always recommend booleaning together objects and checking the files created. Its not a long process once you know what you're doing. For example this axe took less than 3 minutes to boolean and fully check over in a couple of different programs to check suitability.

[@imonseii1436]

@@ArtisansofVaul that is also correct. I just find that sometimes it takes a lot of cleanup after a union bool if you care about having clean optimized topology on your models.

[@ericman2323]

Solid.

Cheers 😁

[@sadhappy8860]

Lovely vid. I've had some fun issues with boolean in blender, lol

[@ArtisansofVaul]

Haha. I think we all have!

[@k4x4map46]

nice n quick!

[@ArtisansofVaul]

Thanks. I still haven't found a consistent video length that people prefer so its always good to get feedback on that.

[@k4x4map46]

@@ArtisansofVaul Surely it would depend on the depth of the subject? Ex. haven't fully captured constructive / destructive and it's significance in 3D printing, so def saved that vid and watch it often...sometimes not in a deep learning mood so a quick tip is always refreshing. None of your vids are ever too long (IMO) b/c having a vested interest makes time spent watching totally worth it--not in your case but having adjustable playback speed really helps on this end!! Also you dive right into the subject at hand with a quick overview. On the flipside, one youtuber stated that 3 minutes of viewing length is where the youtube algo's pickup (record) the likes--no way could verify this but definitely use it for your and other channels of interest e.g. hitting the like button 'after' watching minimum 3 minutes. Any-who, the readers digest version comment written here. Not sure who conducted the study, but college education was avg'd at 50 minutes of verbal instruction yet we can watch a movie at 2hrs plus!! I'm thinking it would be difficult to gauge the avg viewer vs. subscriber vs patreon or member? Would def make your videos a downloadable E-reference guide book of sorts!! excellent content!! Your voice and delivery style are totally welcomed!!! 😁

[@ArtisansofVaul]

@k4x4map46 All good points and I didn't know that 3 minute part. 👍🏻

[@MyronReimer]

Hey thanks, Can you explain how you get inside faces to show as yellow while in object mode? That would be very helpful.

[@ArtisansofVaul]

Of course. I have talked through the idea in this video: kzbin.info/www/bejne/paPUpWt8rJykbtE Its at around 8:25. Basically its leaving the face side showing and having turned the inside to yellow and the outside to transparent.

[@StudioHoekhuis]

For my understanding: to bolean two objects is different/better than joining them together?

[@ArtisansofVaul]

Yes. Joining just adds all the mesh to each other resulting in overlaps. Its not a good process unless you have a specific function in mind. People often do it to be lazy.

@@ArtisansofVaul Thanks, love your videos by-the-way 👍
