Editing Library Features

You can change which features are included as part of a library feature in the library feature part document (.sldlfp):

  • To add another feature, right-click the feature to add, and select Add To Library.

  • To remove a feature, right-click the feature, and select Remove From Library.

  • You can edit an existing library feature and save it with a new name (and .sldlfp extension) to create additional, similar library features.

After the library feature is inserted into a part, you can edit a library feature in the following ways:

  • Use the same techniques that you would use to edit any SolidWorks feature, such as Edit Sketch or Edit Feature.

  • Move the library feature to a different location on the target part, by modifying the locating dimensions. Double-click the library feature icon in the FeatureManager design tree to display the dimensions.

  • You cannot edit the inserted library feature.


Edit References in the References folder of the library feature document (*.sldlfp).
