You can already edit a boolean operation in Maya, but there may be a new tool that will make that workflow easier.
Klaudio Ladavac posts a look at an Editable Boolean Tool he is working on for Autodesk Maya.
The toolset will allow you to easily change and alter the boolean after have completed one.
In actuality, Maya has this ability internally, and this is what Klaudio is tapping into for his workflow tools – His Boolean tools simply brings Maya’s less easily accessible stuff to the forefront.
Klaudio is planning to make the Editable Boolean Tools available when they are completed. For now he has posted a few work in progress videos showing off the progression.
