Using boolean on an object that contains several meshes

Support Modeling
1

i have an object with 2 intersecting meshes. i create a cylinder to cut a hole and place it over part of the main object. then i bool difference to cut the hole. it cuts the hole in the part of the mesh where i place the cylinder but the other mesh in the object just disappears!

any idea how to keep the mesh part that isn’t touched by the intersecting (cutter) object?

thx

i would try rotating the cutter slightly or move it around to see if its geometric related. Sometimes doubles caused by the boolean can cause disappearances. Also holes in the mesh can be problematic.
