Hi everybody

I am wondering if there is a script around or is it possible to automate a repetitive task I have. I work in the aviation industry so a lot of the 3D parts we get from our CAD people are peppered with rivet holes. As i am not working in such detail i want to get rid of these, which i can do manually but it takes a long time and there are may pieces.
Attached is a screenshot of a typical piece and the 3dm file.

Currently i take a piece and run 'separate', then i can get a surface which has many holes in it, from here i manually select all the holes edges and delete. What i am looking for is some script which could delete all holes that are found within the outer boundaries automatically.

Any help anyone can offer on this would be greatly appreciated.

Matt
