Split Meshes In Two | Bisect Tool | Blender Quickie

today i'm going to be showing you guys how to cut an object in half with blender's bisect tool so this is blender 2.91 i'm going to keep it really quick really simple you can see here is one of the results here just cutting an object in half so if you want to learn how to do this keep watching tutorial and let's get started okay so i've got a fresh scene open up in blender i'm just going to delete all the default objects and to demonstrate this i'm going to go shift a go to my mesh options i'm adding in a monkey head here just to demonstrate this and i'm also just going to subdivide mine you don't have to do this just give it some more geometry and i'm just going to go to the modifiers and apply that modifier so now i've got this here now if you actually want to see the bisect tool you're not going to see it over here you need to be working in edit mode so select the object you wish to cut in this case it's the susan monkey head and you go up here to object mode and then change it to edit mode you can also hit the tab key to do that as a shortcut so make sure in edit mode over here now if we actually go over here you're going to see a tool here called the knife tool now to see the bisect tool you actually have to left click on this hold in the button and then come down and hover over the bisect and let go and now that bisect tool is selected so if for example if i were to deselect all this geometry here and were to click here nothing would happen for the bisect tool to work you actually need to have an active mesh so make sure to hit a and make sure all of the mesh is active and selected so once that's done make sure you're in your front orthographic view you can hit one on your number pad as a shortcut if that doesn't work for you just make sure to go to view viewport and then go to the front of graphic view over here so what i'm going to do is with this mesh active i'm going to just click somewhere here with my left button and i'm just going to pull out here and you can see this line now this line here is whatever you want to cut so wherever it's intersecting through it's going to cut on that plane okay so my front or graphic view is going to be perfectly head on if i did it from the right view it would be happening from the right if i did it from top that plane would be from the top perspective so i'm just going to go with something like that i'm going to let go now by the way this thing down here you can actually pull that around and rotate it and stuff and that can still give you some um a little bit of play so for example you didn't get it quite right the first shot so go ahead and mess around with that if you want but what i'm going to do now is i'm going to go over here to the bisect tool option so open this up and these settings here are super simple so what we're going to do here is i'm going to show you these first two so if we go to the clear inner so for example i clicked on it it'll get run rid of this half over here if i untick that it'll bring it back if i want it only the other part i can hit clear outer and then it gets rid of that outer part just like that which is pretty cool now for example if i wanted to fill this automatically i can also come here and click on fill and it'll fill that for me now i've got this cut the only downside is now we've lost the other part so i can do the same thing i can untick this one and go to clear inner now we have this part and that is filled because we have the fill button enabled but what i want to do is have both of them so what you can do is just enable untick both of them so you have both parts and then what you can simply do is with this um still active you can see that this cut here is still orange that's active if you hit the v key on your keyboard so hit v and right click click that it'll actually cut that for you so now what you have to do is with that edge still selected you can hit ctrl l or command l and it'll select the active mesh that it's connected to in fact also hold and shift and just select the eye here if you have another loose part and also hit ctrl l just so all of that loose geometry is selected and then we simply need to hit p so this is the shortcut hit p on your keyboard and i'm going to separate by selected now if we hit the tab key or we go manually here into object mode we have two pieces in our object mode now both of these are open as you can see here if i move that piece to the side so what i'm going to do is i'm going to select one tab into edit mode and just go shift alt and then click on the edge here and that'll loop select this whole edge and then if you hit the f key it'll fill that in for you so tab out of edit mode and then select the other piece and then do the same thing shift alt and then click here on edge it'll loop select the whole edge and then hit the f key and it'll feel it for you now tab out of edit mode and here we have two pieces you can play around with them see what you like now if you want to add smoothing to this so for example in shade smooth selected this piece shades move it looks a little bit messy in the edges one thing you can do to fix that is you can add in an edge split and then mess around here with the angle you can do the same for this one here add in an edge split so that is a little tip of the day something i hope is useful for you guys and that you can put into your workflow so i'll see you guys next time for another little tutorial and if you want to learn more stuff like character modeling and rigging i've got all that sort of stuff on my channel the whole nine yards
