Im trying to mill " a thing", but Im having problems to keep my part inside the material. It looks like I only can create bridges when 2,5D profiling. All 3D toolpaths are removing the bridges. How can I keep the part inside my material... with bridges?
Use avoid (containment) regions if you must use 3D MOPS.
Will take some experimentation to get what you want but it can work for you.
