Hi all.  I'm looking for some general feedback.  I am considering presenting an advanced API tips and tricks session at the 2015 SOLIDWORKS World event.  If you were able to attend, what topics would you like to see covered?  Keep in mind that it is typically seminar style for 60 to 90 minutes. 

What would peak your interest or be valuable?  What have you struggled with?  The language used will likely be VBA and/or VB.NET to relate to the largest audience.

Thanks!

Mike
