    Hi. I have a question. When I traverse through the components, how can I get access to a custom property of the actual component?

    Thought this might be helpful to others using this for anything that will have more then 255 lines printed. This takes what would be printed to the Immediate Window and puts it in a text file. The text file needs to be saved and the location needs to be put into the string after Open.

    ‘Demonstrates how to traverse the feature tree of any SolidWorks document _
    in order using a single recursive function.

    ‘Preconditions: Document is open.
    ‘Results: Names and types of all features are printed in the order they appear _
    in the feature tree, with exceptions: _
    a. Lightweight components or any other type of component not fully loaded _
    into memory cannot have some or all features traversed. _
    b. Smart fasteners may be listed in the tree after the component they are _
    fastened to rather than after the Smart Fasteners folder. _
    c. This macro only traverses true features. Not all items listed in the _
    feature manager tree are true features. Use IFeature::GetSpecificFeature2 _
    to get access to a feature’s underlying items.
