Small change to threads tool

[benbrumbaugh]

Please consider having the “modeled” box checked on by default in the thread tool.

I can't speak for the modeling team (I'm a CAM guy), but I don't think that would be the preferred setting. With modeled threads comes increased calculation time, along with more difficult selection of surfaces in the CAM environment. It would be nice to have a user preference to save as your own default settings.
