Thanks for the quick reply.
I thought there was a leak in one of my components because the Cutlist plugin would not print it and because it had no volume. I tried installing Solid Inspector but it did not find any leaks. Once I invoked Solid Inspector, I could not do anything in Sketchup and had to exit the Sketchup application.
Eventually I figured out that my component did not display a volume value because I had used a subcomponent within the component. I removed the subcomponent and Cutlist was able to recognize my component.
I'm still wondering how you exit Solid Inspector.
Thanks,
Jim
