I’m trying to build a wing model for a mold milling. The mold for the wing will be milled from one block and finally should look like below.
I placed a model of the wing at the top of flat block and tried to make a Boolean Union.
As a result I get
“Boolean union failed.”
Both (wing and block) are closed surfaces and have no Naked Edges nor Non-Manifold Edges.
For a week now I have been trying to get it work but no success so far
When I move block that it doesn’t reach a tip of the wing, then it is fine (look below)
If I move a blok that only left side is common with tip, Boolean Union works as well.
Same block moved 1 mm more to the left and Boolean Union doesn’t work.
What could be wrong?
Any support, advices are kindly welcome.
