I am trying to write a macro that does two things.

1.) A Control-Q rebuild

2.) Traverse assemblies and all sub-assemblies for nonread-only parts and rebuild any macro feature in them

I am doing this because calling a "full-full" rebuild (   swModel.ForceRebuild3(false)  ) takes a very long time for our assemblies because it is literally rebuilding every feature in every part and assembly. This "full-full" rebuild comes from: 2016 SOLIDWORKS API Help - Force Rebuild Example (VBA) and was the start of my macro.

This is currently the only way I know how to force a rebuild on lower level macro features. The macro I am trying to write now is meant to replace the control-Q rebuild and search out my macro features and will hopefully be faster than the "full-full" rebuild

I believe I am close and I think I am stuck on the last step, which is is running the SwComFeature regenerate method. 2015 SOLIDWORKS API Help - Regenerate Method (ISwComFeature)

I've already added the swPublished interface library, but when I try to call the regenerate rebuild I getting "Run-time error '91' : Object variable or with block variable not set"

I believe the problem is that I am not setting my ISWcomFeature object properly. I am still pretty green at writing macros so any help is appreciated. The line that is erroring out is bolded below.
