I’m working on a model of an archtop guitar. After some reworking, I have the topology done to a satisfactory degree. Now the problem. Having mirrored and applied the top and bottom, I’m wanting to cut “f-hole” sound openings in just the top. The right and left F-holes were made with curves and converted to a solid.First one, no problem. But, I try to cut the second, and I lose half the body mesh. What gives? Just separating the top and bottom still didn’t make a difference. Copying just the top to a separate file worked, but rejoining it to the rest of the model looks like a Huge headache.
set bool to difference on both of the modifiers.
Already tried that. The top half then disappears. Set both on intersect, and the whole thing vanishes. bleah.
honestly id not go for a bolean workflow at all, but if you do wish to use boolean then id love to have a look at the blend file for further inspection.
Two “complex” objects used in boolean operations can result in mesh computing problems. I would think that the geometry is still there just flipped or distorted. The only real good fix is to then triple the geometry, but that can make future editing problematic at times, and there may be faceting that shows on the surface. Another approach is to go the long way around and model the geometry instead of using booleans.
Is the mesh being cut into with the booleans an n-gon? In my experience, grid filling a large open face (like the end of a cylinder) before doing an operation makes somewhat of a difference. Seems Blender gets a little confused on how to cap it otherwise.
In the end, I had to go ahead and separate the top bottom and sides, cut out the top, and then join everything back together, vert by vert. the problem I saw with just doing the geometry manually was keeping it consistent side to side. Since the model has a cutaway on one side I couldn’t just mirror two halves. However you slice it, it was still more work, and more time than I wanted, but now it’s where I want it. UV mapping is going to be another whole can of worms. The guitar neck is coming along in a separate file. Getting there.
Thanks for the input, everybody!
