Hello all,
complete vex noob here, I am trying to create a seperate group for each point selected via a group range, so that later i can use an add (by group) to join all the points in the created groups together...
Any ideas how to do this?
many thanks!

how do you expect the groups to be separated?
lets say your group is named range_group and contains points 5-7
if you have different group for each point of you end up with groups: group_pt5, group_pt6, group_pt7
then what do you expect Add By group to do?
since each group will contain 1 point it will not create any line
if you however use range_group in Add SOP directly then it will create line through points 5-7
so I guess my question is what are you trying to achieve?
also it's much more efficient to deal with attributes instead of a lot of groups, but also depends on the goal
but just to blindly answer the question on how to create a group for each point of another group in point wrangle:

string source_group = "range_group"; int pts[] = expandpointgroup(0, source_group); foreach(int i; int pt; pts){ string group_name = sprintf("%s_idx%d_pt%d", source_group, i, pt); setpointgroup(0, group_name, pt, 1); }
