Checking for Cavity Examples

In this example, three bodies will be checked for cavities. The left solid body is a shelled block, the faceted body in the middle is shelled with a Basic Hex Infill, and the right solid body is shelled with a 1 mm diameter hole through the top and bottom walls.

A clipping plane is used to show the interior details.

The Cavity tool gives the following results.

The left solid body has one cavity.
The middle faceted body has 42 cavities due to the Hex Infill.

The right solid body has a through hole so no cavities are found. However, the through hole is small (1 mm) and small openings can cause problems for draining the excess material.

Click the Max Opening option and enter "1".

One cavity is now found and the small openings are highlighted in red.
