Allow me to ask a question please, I want to use VEX to create a group of edges to cut seams for UVmapping later, I found the funcion:
int setedgegroup(int geohandle, string name, int pt0, int pt1, int value)
but can't find an example of how to use it, please I really need help here, thanks…

you use it by providing 2 point numbers that are connected by edge and specifying the value
if the value is not 0 an edge defined by those points will be added to it if it's 0 it will be removed
(simply very similar to setpointgroup() or setprimgroup() to which you can find plenty of examples)

the reason you can't find any examples for setedgegroup() is that the function was just added yesterday and as well if you are using build older than 16.0.597, you will not be able to use it

Ohhhh, thanks for answering I'll be downloading an update then……..
