About Suppressing and Resuming Features
Suppressing features is like removing them from regeneration temporarily. However, you can unsuppress (resume) suppressed features at any time.
You can suppress features on a part to simplify the part model and decrease regeneration time. For example, while you work on one end of a shaft, it may be desirable to suppress features on the other end of the shaft.
Similarly, while working on a complex assembly, you can suppress some of the features and components for which the detail is not essential to the current assembly process.
You may want to suppress features to:
Concentrate on the current working area by suppressing other areas.
Speed up a modification process because there is less to update.
Speed up the display process because there is less to display.
Temporarily remove features to try different design iterations.
 
* Unlike other features, the base feature cannot be suppressed. If you are not satisfied with your base (first) feature, you can redefine the section of the feature, or delete it and start again.
