Actually, let me be more specific... I tried to pare down both a script and an add-in to the bare minimum to reproduce the problems I'm having (they are both supposed to do the same thing).
The first listing is a python "script" that mostly functions as intended. If you select a sketch curve, it selects ALL curves in that same sketch. There is one issue with this one that hopefully someone can answer: Why doesn't the ui.selectEntity function display the prompt as it's supposed to. (On my computer it shows nothing, although it does accept my selection).
The second listing is a python "add-in" with a command definition that allows the user to select that initial curve. The problem with this one is as I originally described: it doesn't keep the selections that are made. In addition, it seems to only select ONE of the curves, even though all of the "add" methods ARE being called within the loop (ie: it seems to only keep the LAST "add" since the message box shows 1 instead of the actual number of curves in the sketch).
Again, my 3 questions are:
- Why doesn't ui.selectEntity display the prompt as it's supposed to according to the api docs
- Why doesn't the add-in version of the script keep the selections after closing the messagebox?
- Why is it only selecting ONE of the curves instead of all of them (the loop is the same in both versions below)
Thanks for any help...
