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.
