Compute Watertightness Statistics Tool
![]() |
If you are still reading this section, even after the warnings in the section about Correction Realities, that must mean you are interested in learning how to turn non-watertight geometry into watertight geometry. The Compute Watertightness Statistics Tool is a good place to start.
This tool is a strictly informational tool. It counts all geometry in the current active Group (or in the entire model, if you are not editting any Group), distinguishing between watertight and non-watertight geometry; then it presents its finding to you through a dialog box similar to that shown in the following figure.

The results are broken down into Edges, Faces, Groups (including sub-Groups), and Components (including sub-Components). They are reported in the form [A] / [B], where [A] is the number of non-watertight Entities of the corresponding type found and [B] is the total number of those Entities. Therefore a return of "Edges: 4202/10960" means that the Compute Watertightness Statistics tool found 10960 Edges total, of which a little over 4000 were non-watertight.
Edges are considered non-watertight if they fail the Golden Rule of Watertight Geometry. Faces are never non-watertight (the number is displayed simply to give you a sense of how many Faces there are in the model). Groups and Components are considered watertight if every one of their composite geometries is valid.
