There are multiple ways to initiate a CATScript macro in CATIA V5. Did you know that it is possible to invoke your macro through a tool bar icon? How do you create an icon for your macro? Go to tools >customize >commands > macros > show properties. Next, simply define a logo for your macro by picking one from the 180 plus icons to choose from (or browse to your own custom made icon) and then drag and drop it into the menu bar where you want it. It's that easy. So now you should have three ways to run your VBA CATScripts: going to Tools>Macro>Macros, hitting Alt+F8, or by clicking on your icon in a toolbar.
