I'm hoping to create a macro that will let me manually select a sub-assembly in the tree and then run the macro through a hotkey to increment the sub-assembly to its next configuration. I've previously only created very simple macros or edited complex ones to slightly modify their function. Now I'm trying to use the online API help to try creating such a macro from scratch, but it seems quite difficult to find what I should even be searching for. I recorded a macro to start off with that basically does what I want, but it is too exact in it's funtion calls to allow me to run it again and again (ie; it keeps calling for the same configuration name). So far, it seems like CompConfigProperties4 is what I'll probably use according to my initial macro recording. I'm looking for some help/pointers on what functions I might want to use and any other tips you can give me. Any suggestions on other downloadable macros that might have pieces of code I an use would also be much appreciated.
