Advanced Boolean Engine and its Layers

The Advanced Boolean Engine (ABE) is a set of geometric processing commands to perform layer operations such as AND, ANDNOT, OR, XOR, TOUCH, INSIDE, and OUTSIDE. ABE can also do SIZE, GROW, and SHRINK operations.

ABE supports multithreading to run multiple layer operations in parallel.

Here are a few limitations of ABE:

• ABE does not operate on all-angle geometries. Only octalinear shapes (90 and 45 degree angles) are supported.
• ABE layers are flat, non-hierarchical layers.
• ABE layers do not preserve logical connectivity.
