Hmm, yes I am on Windows. On the Windows side, BooleanDifference can be used on the command line, and is also available through the Solid menu. Boolean2Objects lets you select two objects to Boolean, then you can left click to iterate through all the possible solutions, when you get the one you want right click or enter completes the command.
Over here on your model, BooleanSplit fails, but BooleanDifference and Boolean2Objects work (as does trim ).
On Windows, when in the Dir command, you can click the surface, or hit the ‘f’ key.[quote=“Ashley_Dell, post:10, topic:44197, full:true”]
what object am I trying to ‘dir’? the green front? or the cutting object?
From the original file you posted, you need to flip both of them.
I would think of Booleans as nothing more than intersect / trim shortcuts. They can save a few moments when they work well, in certain situations, but you shouldn’t feel like you have to use them, and often times (like this case) they take a lot more effort that finding an easier route. When Booleans fail, almost always the first diagnostic should be using Intersect to be sure the intersection is complete. If the resulting intersection curve is good, you can use that to trim, if not, it can show you where the point of failure is.
