alt f11 to open vba editor
at the top left there is a browser with application project and/or document project. there are lists of modules, forms, classes, etc.etc. and in a module there are your macros.
always use application project for your general macros so they are always available in all documents.
that I can't find anything anymore means that you once found them?
Do you remember where you originally copied them?
in application options>file>project vba by default find the file location (usually default.ivb) where macros are registered: check that there is and, in case you had the original blank also recovered from an old version of inventor or a colleague try to point to what maybe corrupted the file (I had happened sometimes).
no...I simply override the menu files...importing it from in 2016...first exported and then imported...I overwritten lxml...very probabbly was corrupt the ribbon file
