Hello, community!
When I import a stl file, I have no way of knowing whether it is closed (other than the visual search for a green colored hole).
Is there a simple way to ensure that the imported STL file is closed?
I appreciate the responses in advance.
Thanks
Import data doctor has some tools to help identify and correct geometry of import features. Having said this, the quickest method to identify open quilts is to use a custom color scheme to increase contrast of open edges of quilts. I would typically use a black background and display the import geometry in wireframe and look for the open edges based on the color. You may need to zoom in on areas to see them.

Thanks @tbraxton @, but your answer does not meet my need at all. I'm asking about facet model, and IDD doesn't check stl.
Thanks
What version of Creo are you working in? Do you have a "bad" stl file as an example that you can post here? If the import data is not closed, is it not a surface model when imported? If it is an open quilt upon import then IDD should be accessible. In past releases that is my recollection of what happened when importing STL into part mode, perhaps that has changed with new versions.
To edit facet models, you need to use the Creo Restyle extension which is an optional add on. If you have this option installed, then you can access this functionality to close holes in a facet model.

Hi @tbraxton
I work with Creo 10. I've attached an example of an open stl (which I opened 😎).
I repeat, IDD does not support imported STL files.
The concept of using a dark mode is well-known, but it is a "nice to have," rather than a definitive analysis. The question of "where" is secondary.
IDD will not work with facet features in Creo 7+, I am not sure in what release this changed as IDD at one time did deal with STL import data. This shows how long it has been since I faced this issue of bad STL mesh.
For facet features REX module is required to work with them. I am not aware of any automatic validation tools to check the STL data on import and identify specific geometry issues. I am not well versed in the use of the REX module but maybe others here can offer some insight into workflows or best practices.
For stl files specifically, there are some online repair tools I have used on occasion. I don't remember which one(s) i have used but I just google for STL repair tool
