thanks, it works for commands, but I can't find the right syntax for functions
i used a workaround, where i defined a command that just calls the function i need
in 2014, for the Case ObjectId,
this line is givng a run time error (unsupported type in command() method )"
resbuf.Add(New TypedValue(CInt(LispDataType.ObjectId), id)
Not sure if this case ever woked in previous versions. This is a for a new routine for civil 3d featurelines
Tony Tanzillo shared a wrapper for the undocumented runCommand() method which is safer the P/Invoking acedCmd.
Have a look here.
so actually my problem was that I was sending a 3d point object to the _aeccbreakfeatureline command, which expects a station, so it nothing to do with the code in question.
