Can you cut a bool

This should be our final result : A mesh with cutout and proper mesh flow. Search for: Search. Use Boolean Modifier. To keep the tutorial simple we will attempt to cut a hole through a simple cube. So lets get started.

Requirements: Time : minutes Software : Blender 2. In the mesh settings of the cylinder, change the vertices count from 32 to 8. This is what the Cylinder should look like. Now the select the cube always select the object you want the cut through. Use the Picker icon and select the cylinder. Now we can see the active cut out of the cylinder through the cube. To solve most Boolean problems, we can move the object a little in any direction.

Also, sometimes you may have multiple meshes in the same object cutting into a base mesh. Separating these and making sure that scale is applied and having normals facing outwards is a good troubleshooting start. Since version 2.

Note: I will call the object with the modifier on it the host object or base object. I will also call the object targeted by the Boolean modifier, target or Boolean object.

The following are the possible operations. We also have the overlap threshold value slider. This is one of our defenses against a misbehaving Boolean. We should keep this value at an all-time low.

The default value is 0. However, if you have faces that are just barely overlapping this value can be used to either ignore those parts or tweaked to just precisely leave them within range to be included. Having a too high value can sometimes cause loose edges being generated that shoots off in different directions. If you need to apply a Boolean modifier, check wireframe viewport mode first and see if you can spot any details or loose edges that float off.

According to the Blender manual , there are some limitations to the Boolean modifier. Booleans work best on manifold or watertight meshes. There are a handful of tricks we can try if we run into an uncooperative Boolean. I usually have a few steps that I go through whenever this happens.

The first steps make sure we have a watertight mesh. In later versions of Blender, there is now an exact solver, in the modifier settings switch from fast to exact if you can spare the speed loss. If not, there are plenty of actions we can take to make the fast solver work.

This just tells Blender that the scale of this object as it is right now is the new starting point. Related content: How and why do we apply scale in Blender? Then try to remove doubles. After recalculating normals on both objects I was able to boolean just fine. Here's the solved file:. Sign up to join this community. The best answers are voted up and rise to the top.

I would have recommended manually modelling one hole on a short section of the barrel and then using an array as long as the cylinders are equally spaced.

However, because the barrel gets smaller towards the end, I'm not sure this would work. It might be a starting point though. Please upload your file so we can inspect it and give a meaningful answer. But first I want to be sure that there's no way of fixing this dumb problem. Add a comment. Active Oldest Votes. For the modifier's Operation choose "Difference". For the Object field choose the object that will do the carving.

Apply the Boolean Modifier and delete your carving object. The solution for your case It was caused by conflicting normals, as I mentioned in one of the tips above. Improve this answer.
