How to getting access to and use features in other AddIns

I want to make some automated processes in a add in for solidworks called SigmaTube.

How do i get access to features in add ins?

You have to ask SigmaTube.

Okay Josh, I will try

You can use ISldWorks.GetAddinObject to access commands in another Add-In but, as Josh has commented SigmaTube would need to expose the commands to allow you to call them.

If you program, you already know that the only publicly available functions are the ones you make public.

Most likely someone with limited programming knowledge, sort of like me, that is able to create mini macros and sometimes correct minor programming errors.

Most likely he’s never developped something from scratch before and now is trying to.
