The issue is as desribed in title. I’ve got a first part of script (by Mitch Heynick - SimplifyCrv does not work) for simplifying near-circles coming from braille font of TextObject into real circles in order to make half spheres of real braille tactile font (2nd part of the script).
The problem is that after selecting near-circles for simplification and running the simplifying function, I want then to select next objects for simplification. The prompt runs to ‘Select Braille dots’ but I am not able to select any feature in the program.
I wonder if an issue is that I should somehow stop executing the first part of script so that I can freely proceed to 2nd part? What should I do? Hopefully the description is not too chaotic. Thanks in advance!
