Issue:

Why is the bounding box larger than my implicit model?

Applies to:

• Implicit modeling

Cause:

This occurs because it isn't possible to create a guaranteed exact bounding box on all implicit operations. 

Solution:

There are two solutions for the error.

1. Use the 'Refine Bounding Box' with Grid Size value.

2. If you need an exact bounding box, convert the Implicit Body to a Mesh body. The Mesh part will have an exact bounding box.
