Hi @berry.lejeune. Here is a link to the SolidWorks online help website for their API (Application Programming Interface) related stuff. Keep in mind that an application's API being exposed so that users can access it through exterior programming means is not the same as iLogic. In Inventor, iLogic is a free, built-in ApplicationAddIn of Inventor, which provides tons of its own built-in shortcut ways of working with Inventor's API through one specific coding language...vb.net. The API can also be accessed through the VBA Editor in both programs, but again, that is not iLogic, and uses a different programming language, although very closely related. You can see within the help documentation listed at the link I provided, that it makes mention of 'Lisp', which you might find is familiar. I am not 100% sure at this point, but that is likely the same coding style that has been used to help automation efforts within AutoCAD for a really long time. Inventor also has an SDK package that can be installed to aid you in working with its API through the use of Microsoft Visual Studio (a massive, external, standalone coding platform), but again, that is a completely different than iLogic.
