Hi , Dan

unfortunately , i've removed all the ".mm" in your code , if the diamter of the circle is 50 mm ,
this will hang , but it's fine if the diameter is 20mm , this is the reason why i said it seem to be related to the diameter of the circle instead of decimal place or array type.

Hi , TIG & Dan

thank you for you reply , to confirm this is not the problem of decimal place , i've removed all the decimal place from the array, but it still hang. I found the major problem is the diameter of cicle , if i change it to 50mm it will hang. (but if you run "followme" manually , it won't hang even you set the diameter to 100mm)

Hi , Dan

thank you very much , your script is work , but unfortunately , all the value i'm using is "inch" instead of "mm"

once i change your script to "inch" , it still hangs , but it's fine if i run "followme" manually.

Hi , Everyone ,

everytime i run the following script , my computer was hang (same in a few computers) , if i remove pts[5] to pts[9] , it can run properly , i found the problems is "followme" causing the issue.

I'm thinking this is the problem of Sketchup , is there anyone have the same problem ?
