Bool Tool seems to union, difference, and intersect in the way that I expect. I later noticed this issue again even with the updated version. https://docs.blender.org/manual/en/latest/addons/object/bool_tools.html
END ANOTHER UPDATE
EDIT UPDATE Here is the .blend file
Two possible solutions
- Upgraded from Blender 3.0.0 to Blender 3.6.5
- Was not using Merge by Distance
I am trying to make a custom gear to attach to my 6V motor. In short, I could use help with the correct steps to use a boolean modifier on a gear in Blender so I can create the desired shape. I come from a openSCAD background and trying to learn Blender 3.
Using the Extra Objects add on I am adding a gear from the mesh selections. I am able to export this to an STL and I can slice this correctly in Cura.
When I import the axle shape to remove I use the boolean modifier on the gear and make sure to hit apply. If I hide the imported object the full gear shows as if the boolean was not performed.
I tried to solidify the created gear, thinking that might be part of it. However I am unable to get the boolean modifier to apply as I wish.
I decided to see if I could get the boolean modifier to work on a cylinder, I see the correct shape in both object and edit mode. Exporting to STL using selected items I am able to view the STL in Cura. And slicing works as expected.
So I decided to create a gear where the cylinder is the base. Remove the axle and apply the boolean modifier. Add the gear around the cylinder with enough base to overlap. Join these objects. Shows up in Cura with xray errors and slices incorrectly. I am pretty sure this is due to me creating the object in Blender incorrectly as I have seen this with other objects and been able to adjust my design.
