I was trying out boolean modifier with simple meshes. Overall it works as described. For example if I choose a cube and a cylinder. However when I try to do a union between an icosphere and a cylinder it does not work.
To be really clear start a new file, insert an icosphere, insert a cylinder, rotate it 90 around X and then move the cylinder so that you have a circular intersection with the icosphere. The cylinder should be centered on a horizontal radius of the icosphere. Add a boolean to the icosphere, set it to union and choose the cylinder. Apply the modifier. Remove the cylinder. There is no union.
Anyone have any ideas?
mrorangekitty seems to work perfectly fine, if this is what you mean:
(Also Applying the Modifier and deleting the Cylinder works as it should.)
What Blender version are you using?
mrorangekitty, it seems to work ok for me too. Other than what spikeyxxx said, the only other thing I can think off is the Boolean is not applied before deleting the cylinder.
Thanks for your help. It is working now. Not sure what happened.
