Reveal (display or delete) all feature hidden in the SOLIDWORKS Feature Manager tree

This VBA macro helps to reveal all features in the active SOLIDWORKS model which are hidden in the feature manager tree.

There are may be various reasons for the features to be hidden in the SOLIDWORKS files. In some cases those feature are invalid or dangling. This could cause unpredicted behavior of SOLIDWORKS, including performance problems or instability such as crashes or hanging.

Create a new macro and paste the module code into the macro
Add new user form into the macro and name it FeaturesForm and paste the code. The macro structure should look similar to the image below

Add controls to the form and name according the to image below. Optionally specify more attributes to controls such as caption.
- List Box named lstFeatures
- Button named btnShow
- Button named btnDelete

As the result of running the macro all hidden features will be populated in the list. Select (or multi select) features in the list and click Show or Delete button to either show or remove features from the model.

Hidden features displayed in the Feature Manager Tree

!IMPORTANT: use delete option on your own risk. In some cases the hidden feature is a valid feature created by SOLIDWORKS or 3rd party applications. For example attributes can be created as a hidden features and can contain important information. Removing this can have unexpected results.

To hide the feature use the following macro macro.
