Blender Mesh Intersect Tool
Why Blender Stack Exchange recommends it
Blender Stack Exchange answerers point people to it as the canonical demo of Mesh > Faces > Intersect when asked how to cut, slice, or clean up intersecting geometry.
Recommended by 6 people across 6 different months, 2014 to 2021.
What it is
A short demo by Blender developer Campbell Barton of the Intersect tool he added in Blender 2.72. It shows the tool cutting intersecting faces within a single mesh in edit mode, as an alternative to Boolean modifiers.

You could use a couple different methods: Boolean modifier [LINK] : Add a boolean modifier on the object you want to cut a hole in, Create an object to "subtract" from the main object Set that object in the boolean modifier. You can press E while hovering over the object selection field to set the field by clicking on an object in the 3D view. [LINK] knife project tool [LINK] : Add a circle or some other object to define the outline of the hole With the circle selected, ⇧ Shift select the object you want to cut a hole in and enter edit mode ( ↹ Tab ) Select the faces you want to cut, then click knife project in the tool shelf . If you want to cut all the way through the mesh, enable Cut thro

There are two methods that are standing out to me. One is the boolean modifier. For this, you need to make the crystalline structures a separate object. Than add a boolean modifier to one of the objects and use the union type. This will actually join the objects, the downsides are that it can create sloppy topology so it really depends on how willing you are to have n-gons and triangles in your mesh. The other one is the intersect tool which is new with 2.72. For this you need to be in edit mode and have everything selected. The easiest way to find it is to use the spacebar search menu. Just search "intersect". Here's a demo on the intersect tool: link [this video] This won't join the two meshes

The new Intersect Tool added in 2.72 will cut up intersecting faces - this is for meshes that are part of the same object, not multiple intersecting objects and can be found in Mesh->Face->Intersect. Campbell explains it in this video [this video] There are a couple of addons that can help with boolean operations. One is Blender sculpt tools [LINK] - the name is a bit misleading as it also works outside of sculpt mode. Another is BoolTool [LINK]

Looking at your .blend I can't really make sense of how your meshes got like that or why the cube is ripped open and non-manifold. However, maybe the Intersect Tool ( [this video] ) could be used in your case to join the meshes instead of using a Boolean Modifier. Then any leftover internal faces could be found using Select Non-Manifold, and deleted. Might that be a solution for you?

For quickly cutting intersections in edit-mode, the intersect tool can be used for this. Simply add a plane in edit-mode, access from the Menu: 'Mesh->Faces->Intersect' ( demo video [this video] ) Advantages over bisect is you can intersect more complex shapes. Advantages over boolean is it doesn't have to calculate inside-outside, its an editing tool instead. Also its less hassle to setup then boolean. Although they are really intended for different purposes.

I am pretty new to Blender but I looked at some tutorials on how to build my own structure etc. I found one [this video] at about 2:05 minutes, where they select all inner vertices with some clicks and removes them afterwards. Can somebody help me to redo this on my objects? I have for example two cubes and they intersect each other. My next steps are joining these two cubes, I click in edit mode on Mesh > Faces > Intersect Then I choose Self intersect and now I am losing track of the video, where he does Link select and inverts the selection and then magically he just removes the selected parts... Can somebody help me on this a little. If I let the internal geometry stay, my printouts in the pri

Beginning from the very starting point, you asked about using **Mesh** > *Faces* > *Inetrsect* function described by Campbell Burton [this video] . To repeate these actions on your example, with those cubes *joined* select all and use the function [LINK] , that's all.

@a52 answer updated. This tool is present in Blender 2.72+ and it's located in *Mesh* > *Faces* > *Intersect* or you can press `Space` and type tool's name. See release video [this video] for more info on it.

I was trying to follow this tutorial made in Blender 2.71.x but I haven't figured out how it can be done in 2.93.x yet. He pulls out the self intersecting geometry but when I try and do it, it says no intersections found . His example: [LINK] My example keeps saing no intersections found .
