With the Defeature tool, you can remove details from a part or assembly and save the results to a new file in which the details are replaced by dumb solids (that is, solids without feature definition or history). You can then share the new file without revealing all the design details of the model.
The Defeature PropertyManager provides tools for manual and automatic selection of details to keep and remove.
To open this PropertyManager:
