Boolean with offset does not work on complicated fillet surfaces

In this document there are two Boolean. The first leaves out the two surfaces that cause a failure. The second only has the two surfaces that cause the failure.

The offset of 0.015" is being used. Without the offset it works.

Initially I selected 0.015" offset all given that is the desired result.

Why doesn't this work?

    I don’t know why the boolean with offset failed.


    But if you’re interested in a workaround,
    see the document below.

    Thanks for your feedback. Interesting solution. I've submitted a bug report to find out what the issue is before moving forward.

    I got it to work by using a single boolean — the way you wanted it to work

    I used REPLACE FACE to eliminate the lines shown below. Then I was able to use a single boolean with offset on ALL THE FACES.

    I saw that the no offset worked but did not realize there was a second step that could be used to add the offset. So one would ask this question. Why not break it into two processes? No offset followed by adding the offset. A hack perhaps but it eliminates future head scratching and hides it from the users.

    This solution worked just fine so Ill be moving on. :)

    It did not quite work after all.
