Great tutorial, just one question, I work as a design engineer, my computer at work has solidworks and edrawings 2018 installed, the thing is that i already tried doing this by inserting an object in the presentation wich shows me the edrawings 2018 control and an error always occurs, I´ve tried with the developer tool and the list does not shows the edrawings 2018 control, i have the option of looking for the controller in the windows explorer, do you know what kind of file is it? or should it be a problem with the installation of the software?... thaks
